DETAILED DESCRIPTION

One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

Certain energy sources (e.g., electrical, mechanical, hydraulic, pneumatic, chemical, thermal) may be controlled and/or distributed using various types of equipment. Oftentimes, to properly perform maintenance operations on these types of equipment, technicians may place the equipment offline. Placing equipment offline may include removing the equipment from a larger system or circuit by opening a circuit breaker on a supply side of the equipment. However, it should be noted that although the equipment is placed offline, control circuitry of the equipment may remain powered on (e.g., 120 volts) for configuration, communication, and the like. To ensure that the offline equipment is not altered or placed online by another technician, the equipment may be placed offline according to a lockout-tagout protocol. The lockout-tagout protocol may specify certain practices and procedures that technicians should employ when placing certain equipment offline. For example, the lockout-tagout protocol may specify that the operator placing a piece of equipment offline may place a physical lock on the piece of equipment that physically blocks the piece of equipment from being placed back online. With the foregoing in mind, in some instances, the technician may use a computing device (e.g., electronic device), such as a tablet computer or the like, to track equipment that have been placed offline using the lockout-tagout protocol. The computing device may include software that guides the technician through the steps of placing a certain piece of equipment offline according to the lockout-tagout protocol. In addition, the software may track data related to placing the equipment offline when lockout-tagout protocol does not apply.

Generally, equipment is placed offline according to the lockout-tagout protocol when the equipment or another related (e.g., downstream) piece of equipment may not be operating as desired. As disclosed, the lockout-tagout software may guide the technician with regard to properly placing the equipment offline and may also maintain various statistics (e.g., time offline, number of maintenance operations) regarding the equipment being placed offline. In certain embodiments, equipment may be placed offline for reasons other than service procedures that require following the lockout-tagout protocol. For instance, certain pieces of equipment may be placed offline for seasonal maintenance, for security purposes, or the like. In this case, the lockout-tagout software may receive information from the technician regarding a reason for placing a piece of equipment offline. In some embodiments, the software may determine the reason for placing the piece of equipment offline based on the type of maintenance or service done to the equipment. The reasons may include a scheduled maintenance, a routine seasonal machine change, a diagnostic analysis, or the like. In some embodiments, after receiving or determining the reason for placing the piece of equipment offline, the software may determine whether the lockout-tagout protocol should be observed when placing the equipment offline. For example, certain governmental regulations specify that the lockout-tagout protocol should be followed when placing certain types of equipment offline for particular reasons. However, the lockout-tagout protocol may be unnecessary when placing the equipment offline for reasons not specified by the governmental regulations. As such, in some embodiments, if the software determines that the reasons that a piece of equipment is being placed offline do not correspond to certain governmental regulations, the software may present instructions indicating that the operator may not have to use lockout-tagout locks and/or tags when placing the equipment offline. In addition to providing instructions to assist the operator with properly placing equipment offline, the software may also track the reasons for placing the equipment offline and various statistics regarding the equipment being placed offline. These statistics may be helpful in keeping track of the health of the equipment and overall state of the facility in which the equipment operate.

Additionally, in some embodiments, the software may also be used to secure a respective piece of equipment or block the respective piece of equipment from being placed in service. As such, the software may be used as a security feature to block a piece of equipment from being activated remotely. The software may perform one or more operations that result in the piece of equipment being incapable of activating in a normal manner. For example, the software may remove a power supply (e.g., open a circuit breaker) from a piece of equipment or a controller associated with the piece of equipment, delay reactivating the piece of equipment until desired updates are installed, send a command to a lock device that may physically lock the piece of equipment, and so forth. Additional details regarding the above-described embodiments will be discussed in detail below.

FIG. 1 is a diagrammatical representation of an exemplary control and monitoring system 10, in accordance with embodiments presented herein. In FIG. 1, the control and monitoring system 10 is illustrated as including a human machine interface (HMI) 12 and a control/monitoring device or automation controller 14 adapted to interface with devices that may monitor and control various types of industrial automation equipment 16. It should be noted that such an interface in accordance with embodiments of the present techniques may be facilitated by the use of certain network strategies. Indeed, an industry standard network may be employed, such as DeviceNet, to enable data transfer. Such networks permit the exchange of data in accordance with a predefined protocol, and may provide power for operation of networked elements.

The industrial automation equipment 16 may take many forms and include devices for accomplishing many different and varied purposes. For example, the industrial automation equipment 16 may include machinery used to perform various operations in a compressor station, an oil refinery, a batch operation for making food items, a mechanized assembly line, and so forth. Accordingly, the industrial automation equipment 16 may comprise a variety of operational components, such as electric motors, valves, actuators, temperature elements, pressure sensors, or a myriad of machinery or devices used for manufacturing, processing, material handling, and other applications.

Additionally, the industrial automation equipment 16 may include various types of equipment that may be used to perform the various operations that may be part of an industrial application. For instance, the industrial automation equipment 16 may include electrical equipment, hydraulic equipment, compressed air equipment, steam equipment, mechanical tools, protective equipment, refrigeration equipment, power lines, hydraulic lines, steam lines, and the like. Some example types of equipment may include mixers, machine conveyors, tanks, skids, specialized original equipment manufacturer machines, and the like. In addition to the equipment described above, the industrial automation equipment 16 may also include controllers, input/output (I/O) modules, motor control centers, motors, human machine interfaces (HMIs), operator interfaces, contactors, starters, sensors 18, actuators 20, drives, relays, protection devices, switchgear, compressors, sensor, actuator, firewall, network switches (e.g., Ethernet switches, modular-managed, fixed-managed, service-router, industrial, unmanaged, etc.) and the like.

In certain embodiments, one or more properties of the industrial automation equipment 16 may be monitored and controlled by certain equipment for regulating control variables used to operate the industrial automation equipment 16. For example, sensors 18 and actuators 20 may monitor various properties of the industrial automation equipment 16 and may adjust operations of the industrial automation equipment 16, respectively.

In some cases, the industrial automation equipment 16 may be associated with devices used by other equipment. For instance, scanners, gauges, valves, flow meters, and the like may be disposed on industrial automation equipment 16. Here, the industrial automation equipment 16 may receive data from the associated devices and use the data to perform their respective operations more efficiently. For example, a controller (e.g., control/monitoring device 14) of a motor drive may receive data regarding a temperature of a connected motor and may adjust operations of the motor drive based on the data.

In certain embodiments, the industrial automation equipment 16 may include a computing device and/or a communication component that enables the industrial equipment 16 to communicate data between each other and other devices. The communication component may include a network interface that may enable the industrial automation equipment 16 to communicate via various protocols such as EtherNet/IP®, ControlNet®, DeviceNet®, or any other industrial communication network protocol. Alternatively, the communication component may enable the industrial automation equipment 16 to communicate via various wired or wireless communication protocols, such as Wi-Fi, mobile telecommunications technology (e.g., 2G, 3G, 4G, LTE), Bluetooth®, near-field communications technology, and the like.

The sensors 18 may be any number of devices adapted to provide information regarding process conditions. The actuators 20 may include any number of devices adapted to perform a mechanical action in response to a signal from a controller (e.g., the automation controller 14). The sensors 18 and actuators 20 may be utilized to operate the industrial automation equipment 16. Indeed, they may be utilized within process loops that are monitored and controlled by the control/monitoring device 14 and/or the HMI 12. Such a process loop may be activated based on process inputs (e.g., input from a sensor 18) or direct operator input received through the HMI 12. As illustrated, the sensors 18 and actuators 20 are in communication with the control/monitoring device 14. Further, the sensors 18 and actuators 20 may be assigned a particular address in the control/monitoring device 14 and receive power from the control/monitoring device 14 or attached modules.

Input/output (I/O) modules 22 may be added or removed from the control and monitoring system 10 via expansion slots, bays or other suitable mechanisms. In certain embodiments, the I/O modules 22 may be included to add functionality to the control/monitoring device 14, or to accommodate additional process features. For instance, the I/O modules 22 may communicate with new sensors 18 or actuators 20 added to monitor and control the industrial automation equipment 16. It should be noted that the I/O modules 22 may communicate directly to sensors 18 or actuators 20 through hardwired connections or may communicate through wired or wireless sensor networks, such as Hart or IOLink.

Generally, the I/O modules 22 serve as an electrical interface to the control/monitoring device 14 and may be located proximate or remote from the control/monitoring device 14, including remote network interfaces to associated systems. In such embodiments, data may be communicated with remote modules over a common communication link, or network, wherein modules on the network communicate via a standard communications protocol. Many industrial controllers can communicate via network technologies such as Ethernet (e.g., IEEE802.3, TCP/IP, UDP, EtherNet/IP, and so forth), ControlNet, DeviceNet or other network protocols (Foundation Fieldbus (H1 and Fast Ethernet) Modbus TCP, Profibus) and also communicate to higher level computing systems.

In the illustrated embodiment, several of the I/O modules 22 are configured to transfer input and output signals between the control/monitoring device 14 and the industrial automation equipment 16. As illustrated, the sensors 18 and actuators 20 may communicate with the control/monitoring device 14 via one or more of the I/O modules 22 coupled to the control/monitoring device 14.

In certain embodiments, the control/monitoring system 10 (e.g., the HMI 12, the control/monitoring device 14, the sensors 18, the actuators 20, the I/O modules 22) and the industrial automation equipment 16 may make up an industrial application 24. The industrial application 24 may involve any type of industrial process or system used to manufacture, produce, process, or package various types of items. For example, the industrial applications 24 may include industries such as material handling, packaging industries, manufacturing, processing, batch processing, and the like.

In certain embodiments, the control/monitoring device 14 may be communicatively coupled to a computing device 26 and a cloud-based computing system 28. In this network, input and output signals generated from the control/monitoring device 14 may be communicated between the computing device 26 and the cloud-based computing system 28. Further, the computing device 26 and/or the cloud-based computing system 28 may be communicatively coupled with a regulations database 29 and may query the regulations database 29 to determine when certain protocols should be performed for certain operations. For example, the regulations database 29 may include government regulations that specify that certain protocols (e.g., lockout-tagout) should be followed when certain operations (e.g., placing a piece of industrial automation equipment 16 offline) are performed for certain reasons (e.g., scheduled maintenance, abnormal behavior). As discussed in detail below, appropriate instructions to carry out the desired operation may be displayed on the computing device 26 when the operation is being performed for a reason specified in the government regulations stored in regulations database 29. Additionally, the regulations database 29 may include industry regulations, proprietary regulations, or the like.

FIG. 2 is a schematic representation of a communication network 30 that enables devices to communicate with each other within an industrial application, in accordance with embodiments presented herein. As such, the communication network 30 enables devices that are part of the industrial application 24 to communicate with each other and with other devices that are not part of the industrial application 24. As mentioned above, the industrial application 24 may be in the material handling, packaging industries, manufacturing, processing, batch processing, or any technical field that employs the use of the industrial automation equipment 16.

The cloud-based computing system 28 may be a cloud-accessible platform that may include one or more servers, one or more computing devices (e.g., general purpose computers), and the like. In any case, the cloud-based computing system 28 may include a number of computers that may be connected through a real-time communication network, such as the Internet, Ethernet, EtherNet/IP, ControlNet, or the like, such that the multiple computers may operate together as a single entity. The real-time communication network may include any network that enables various devices to communicate with each other at near real-time or such that data is communicated with each other at near instantaneous speeds. In one embodiment, the cloud-based computing system 28 may be capable of communicating with the industrial automation equipment 16 and the computing device 26. As such, the cloud-based computing system 28 may be capable of wired or wireless communication between the industrial automation equipment 16 and the computing device 26.

FIG. 5 is a flow chart of a method 50 employed by the computing device 26 for providing instructions for the placing industrial automation equipment 16 offline based on defined rules (e.g., governmental regulations), in accordance with embodiments presented herein. The method 50 may be implemented as computer instructions stored on the one or more tangible, non-transitory computer-readable medias (e.g., memories 37) and executable by the one or more processors 36. Although the following description of the method 50 is provided with reference to the processor 36 of the computing device 26, it should be noted that the method 50 may be performed by one or more other processors disposed on other devices that may be capable of communicating with the cloud-based computing system 28, the control/monitoring device 14, the industrial automation equipment 16, or other components associated with the industrial application 24. Additionally, although the following method 50 describes a number of operations that may be performed, it should be noted that the method 50 may be performed in a variety of suitable orders and all of the operations may not be performed. It should be appreciated that the method 50 may be wholly executed by the computing device 26 (e.g., tablet) or the execution may be distributed between the cloud-based computing system 28 and the computing device 26.

Referring now to the method 50, the processor 36 may receive (block 52) some input data related to placing a piece of the industrial automation equipment 16 offline. The input data may be entered by a user and include an indication of a particular industrial automation equipment 16 that the user intends to perform a maintenance operation, examine, or inspect. The input data may be received from a sensor 18 of the industrial automation equipment 16. The sensor 18 may send the input data, which may include a request to place the industrial automation equipment 16 offline and a parameter or property of the industrial automation equipment 16. The parameter or property of the industrial automation equipment 16 may be indicative of a potential fault. For example, the input from the sensor 18 may be sent to the processor 36 when the industrial automation equipment 16 has a temperature measurement above a threshold, or the like. Thus, the input data may also include parameter data that involves data that details certain properties (e.g., temperature, pressure, speed) of the industrial automation equipment 16.

The processor 36 may receive (block 54) one or more reasons for placing the piece of industrial automation equipment 16 offline. In some embodiments, the reasons may be entered by the user via a graphical user interface (GUI 45) displayed on the display 42 using the touch screen or one or more input peripherals attached to the computing device 26. The reasons may include a scheduled maintenance, a routine seasonal machine change, a diagnostic analysis, security purposes, or the like. It should be noted that, in some embodiments, the processor 36 may determine the reason for placing the industrial automation equipment 16 offline by analyzing one or more factors, such as the type of maintenance performed, the date/time at which the request was made, and so forth, in relation to historical data stored in the memory 37 and/or storage 38. Additionally, the cloud-based computing system 28 may determine the reason for placing the industrial automation device 16 offline by analyzing the factors mentioned above and comparing them to information stored in the databases 44.

In some embodiments, the processor 36 may determine (block 56) whether the defined rules (e.g., government regulations) stored in the regulations database 29 specify that the industrial automation equipment should be placed offline according to the lockout-tagout protocol based on the one or more reasons. For example, certain governmental regulations specify that the lockout-tagout protocol should be followed when placing certain types of equipment offline for particular reasons. The certain types of equipment may include particularly complex equipment (e.g., large engines with downstream systems) and/or equipment that produces high voltages (e.g., transformer), among others. If the reasons that were provided by the user or determined by the processor 36 and/or the cloud-based computing system 28 match a reason specified for placing the particular equipment offline according to the lockout-tagout protocol in the defined rules, then the processor 36 may provide (block 58) the instructions (e.g., a first set of instructions) for placing the industrial automation equipment 16 offline according to the lockout-tagout protocol. In some embodiments, the lockout-tagout protocol may specify using lockout-tagout locks (e.g., lock device) to physically prevent the industrial automation equipment 16 from being placed online when placing the equipment 16 offline and/or using lockout-tagout tags. For example, one step of the first set of instructions may include actuating a lock device that physically prevents the industrial automation equipment 16 from being placed online In some embodiments, the instructions may be displayed by the display 42 via software executing on the computing device 26.

However, in some embodiments, the lockout-tagout protocol may not be relevant when placing the equipment offline for reasons not specified by the defined rules or regulations. Accordingly, if the software determines that the reasons that the industrial automation equipment 16 is being placed offline do not correspond to certain regulations, the processor 36 may provide (block 60) instructions (e.g., a second set of instructions) to place the industrial automation equipment 16 offline without using the lockout-tagout protocol. For example, the instructions may instruct the user to not use lockout-tagout locks (e.g., lock device) and/or tags when placing the equipment offline. However, it should be noted that the instructions may still take care to instruct the user regarding how to place the equipment offline while omitting certain steps specific for lockout-tagout protocol.

The processor 36 may track and maintain (block 62) various statistics regarding the industrial automation equipment 16 that is placed offline. In some embodiments, the statistics may be sent to the cloud-based computing system 28. The statistics may include an amount of time the industrial automation equipment 16 is offline in relation to an amount of time the industrial automation equipment is online, the number of maintenance operations performed on the industrial automation equipment 16, the reasons for placing the equipment 16 offline, whether placing the equipment 16 offline was scheduled or unscheduled, and so forth. The statistics may be used to keep track of the health of the industrial automation equipment 16 and the overall state of the facility in which the industrial automation equipment 16 operate. For example, the statistics may indicate that a particular industrial automation equipment 16 has been placed offline more than a threshold number of times within a certain time period, has been placed offline for a particular reason, and the like. In one example, the processor 36 may determine the overall state of the facility is satisfactory when a threshold number of industrial automation equipment 16 have not been placed offline more than a threshold number of times in a certain period of time. In another example, the processor 36 may determine the overall state of the facility is unsatisfactory when a threshold number of industrial automation equipment 16 have been placed offline more than a threshold number of times in a certain period of time. The processor 36 may display an alert on the display 42 based on the statistics. Further, the statistics may be analyzed to predict when certain events regarding the industrial automation equipment 16 may occur in the future. For example, warnings may be displayed via the computing device 26 that suggest that a certain event may occur in the near future when the industrial automation equipment 16 is placed offline for a recognized reason based on the statistics, which may contain historical data and analysis regarding approximate timeframes for events occurring relative to when the equipment 16 is placed offline for certain reasons. In some embodiments, the processor 36 may control the operation of the industrial automation equipment 16 based on the statistics. For example, the processor 36 may prevent the industrial automation equipment 16 from being placed in service if the industrial automation equipment 16 is placed offline more than a threshold number of times in a certain time period. After collecting data (e.g., statistics), any user may observe the data regarding various equipment 16 by using a computing device 26 to retrieve the data from the cloud-based computing system 28 and to display the data on the display 42 of the computing device 26.

For example, in some embodiments, the processor 36 may retrieve the data (e.g., statistics) from the memory 37 or receive the data from the cloud-based computing device 28 and generate a visualization to be displayed by the display 42. The visualization may include a graphical user interface (GUI 45) that may include a flat layout of the facility and objects representative of the industrial automation equipment 16 in the facility. In some embodiments, the GUI 45 may include a virtual first person view of three dimensional (3D) industrial automation equipment 16 objects that are within a certain proximity to the location of the computing device 26. The industrial automation equipment 16 objects may include one or more selectable links that retrieve the statistics for the particular industrial automation equipment 16 object and display the statistics on the GUI 45. For example, a user may select a link associated with a particular industrial automation equipment 16 and the GUI 45 may display the amount of time the industrial automation equipment 16 is offline in relation to an amount of time the industrial automation equipment is online, the number of maintenance operations performed on the industrial automation equipment 16, the reasons for placing the equipment 16 offline, whether placing the equipment 16 offline was scheduled or unscheduled, and so forth.

FIG. 6 is a flow chart of a method 70 employed by the computing device 26 for physically locking out devices when placing the industrial automation equipment 16 offline, in accordance with embodiments presented herein. The method 70 may be implemented as computer instructions stored on the one or more tangible, non-transitory computer-readable medias (e.g., memories 37) and executable by the one or more processors 36. Although the following description of the method 70 is described with reference to the processor 36 of the computing device 26, it should be noted that the method 70 may be performed by one or more other processors disposed on other devices that may be capable of communicating with the cloud-based computing system 28, the control/monitoring device 14, the industrial automation equipment 16, or other components associated with the industrial application 24. Additionally, although the following method 70 describes a number of operations that may be performed, it should be noted that the method 70 may be performed in a variety of suitable orders and all of the operations may not be performed. It should be appreciated that the method 70 may be wholly executed by the computing device 26 (e.g., tablet) or the execution may be distributed between the cloud-based computing system 28 and the computing device 26.

In general, the method 70 may be used by the computing device 26 to secure a piece of industrial automation equipment 16 or block the piece of industrial automation equipment 16 from being placed in service. As such, the method 70 may be used as a security feature to block the piece of industrial automation equipment 16 from being activated remotely (e.g., from a connected device) or locally (e.g., by the user interacting with the industrial automation equipment 16). This may function as an integral part of a lockout-tagout procedure.

Referring now to the method 70, the processor 36 may receive (block 72) input regarding a request to place a piece of industrial automation equipment 16 offline. As previously discussed, the input may be a request from the user and/or triggered by the sensors 18 based on detected data. In some embodiments, prior to the user entering the input, the processor 36 may have authorized the identity of the user by verifying credentials, scanning a badge, reading fingerprints, using facial recognition techniques, or the like. The processor 36 may determine (block 74) whether the industrial automation equipment 16 is placed offline. If the industrial automation equipment 16 is not already placed offline, the processor 36 may remove (block 76) a power supply from industrial automation equipment or a controller associated with the industrial automation equipment 16. To achieve this, the processor 36 may send a signal to a power source coupled to the equipment 16 to turn off or remove power (e.g., open a circuit breaker, contactor, switch, or relay). It should be noted that, in some embodiments, the signal from the processor 36 may cause the power source coupled to the controller to supply low voltage to the controller. Further, in some embodiments, the processor 36 may monitor the industrial automation equipment 16 and/or controller associated with the offline industrial automation equipment 16 and permit the power to be reactivated via a signal from the processor 36 (e.g., prevents reactivation commands from other devices from reactivating the power).

After the power is removed from the industrial automation equipment 16 in block 76 or if the industrial automation equipment 16 is already offline at block 74, the processor 36 may determine whether the firmware, software, and/or hardware of the industrial automation equipment 16 is updated (block 78). In some embodiments, the processor 36 may check the revision history of the industrial automation equipment 16 being placed offline and any associated industrial automation equipment and/or controllers. For example, the processor 36 may obtain the versions of the firmware, software, and/or hardware included in the industrial automation equipment 16 and consult the cloud-based computing system 28 or the Internet to determine whether the current versions are the latest versions available. If the versions of the firmware, software, and/or hardware are not updated, the processor 36 may retrieve the update (e.g., download files), prompt the user to install the update, and/or install the update when the processor 36 receives installation confirmation from the user (block 80). In some embodiments, the updates may be automatically installed if the update is related to main functionality of the industrial automation equipment 16. Also, in some embodiments, if the hardware is outdated or begins to suffer from declining performance, the processor 36 may prompt the user to install a newer version of the hardware (e.g., processor, hard drive, or memory). In some embodiments, the processor 36 may prevent the industrial automation equipment 16 from being placed back in service until the firmware, software, and/or hardware updates are installed. That is, the processor 36 may deny input from the user and/or sensors 18 to reactivate the industrial automation equipment 16 until the updates are installed. Additionally, in some embodiments, the processor 36 may run various tests after the installation is completed to verify that the installation was performed correctly and successfully before the industrial automation equipment 16 is reactivated.

After the updates are installed or if the firmware, software, and/or hardware are already updated, the processor 36 may determine whether the industrial automation equipment 16 is in a protected mode (block 82). One such protected mode is when the industrial automation equipment 16 is placed offline. If the industrial automation equipment 16 is in a protected mode, the processor 36 may send a command signal to a lock device to physically lock the piece of industrial automation equipment 16 (block 84). In some embodiments, physically locking the equipment 16 may prevent the equipment 16 from being placed back in service. For example, a power switch of the industrial automation equipment 16 may be physically locked in the off position and incapable of being moved to the on position. Also, physically locking the industrial automation equipment 16 may prevent the equipment 16 from being activated remotely (e.g., from another device besides the computing device 26) or may prevent technicians operating on the industrial automation equipment 16 locally. Additionally, when the industrial automation equipment is not in a protected mode, the processor 36 may send a command signal to the equipment 16 to enter a protected mode (block 86). Then, the processor 36 may send the command signal to the lock device to physically lock the piece of industrial automation equipment 16 (block 84). As may be appreciated, the various operations described above may enable the software executed by the processor 36 to prevent the industrial automation equipment 16 from returning to service until desired. The data related to a status of the lock device, the version of the firmware, software, and/or hardware installed in the industrial automation equipment 16, and/or the mode (e.g., protected mode) of the industrial automation equipment 16 may be stored in the memory 37 and/or sent to the cloud-based computing system 28.

As such, in some embodiments, a status (e.g., locked or unlocked) of the lock device, the version of the firmware, software, and/or hardware installed in the industrial automation equipment 16, and/or the mode (e.g., protected mode) of the industrial automation equipment 16 may be visible to the user via the GUI 45 described above. The processor 36 may retrieve the data from the memory 37 and display the data associated with particular industrial automation equipment 16. Further, any user may use a computing device 26 to access the data from the cloud-based computing system 28 and display the information on the display 42 of the computing device 26. As discussed above, the GUI 45 may include a flat layout of the facility including the industrial automation equipment 16 objects arranged in the layout in their relative locations in the facility. The objects may include selectable links that show the data described above. For example, selecting a particular industrial automation equipment 16 may show the status of the lock device as being locked, the mode of the equipment 16 as being the protected mode, and the versions of the firmware, software, and/or hardware installed in the equipment 16. Further, in some embodiments, a message may be displayed indicating that the versions of the firmware, software, and/or hardware are up to date or are outdated.

FIG. 7 is a flow chart of a method 90 employed by the computing device 26 for performing operations when placing the industrial automation equipment 16 online, in accordance with embodiments presented herein. The method 90 may be implemented as computer instructions stored on the one or more tangible, non-transitory computer-readable medias (e.g., memories 37) and executable by the one or more processors 36. Although the following description of the method 90 is described with reference to the processor 36 of the computing device 26, it should be noted that the method 90 may be performed by one or more other processors disposed on other devices that may be capable of communicating with the cloud-based computing system 28, the control/monitoring device 14, the industrial automation equipment 16, or other components associated with the industrial application 24. Additionally, although the following method 90 describes a number of operations that may be performed, it should be noted that the method 90 may be performed in a variety of suitable orders and all of the operations may not be performed. It should be appreciated that the method 90 may be wholly executed by the computing device 26 (e.g., tablet) or the execution may be distributed between the cloud-based computing system 28 and the computing device 26.

Referring now to the method 90, at block 92, the processor 36 may receive an input to place a piece of the industrial automation equipment 16 online. The input may be received from the user entering the request via a graphical user interface (GUI 45) shown on the display 42 or one or more input peripherals and/or the input may be received from a sensor 18 based on certain detected conditions. The various conditions that may trigger the sensor 18 to send the input may include the sensor 18 detecting that a temperature of the piece of the industrial automation equipment 16 has reduced below a threshold temperature for a duration of time, the sensor 18 detecting a reduction in air pollutants, the sensor 18 detecting vibrations that exceed a threshold, and the like.

The processor 36 may determine (block 94) whether power is supplied to other connected industrial automation equipment and/or controllers. If power is not supplied, then the processor 36 may send (block 96) a command signal to reconnect the power supply to the other connected industrial automation equipment and/or controllers. After the command signal is sent and power is supplied or if the power is already supplied, then the processor 36 may determine (block 98) whether a lock device is physically locking the piece of industrial automation equipment 16. For example, the lock device may physically lock the piece of industrial automation equipment 16 by using a physical restraint (e.g., cable, bar) to physically keep a circuit breaker, contactor, relay, switch, or the like, open. If the lock device is physically locking the industrial automation device 16, then the processor 36 may send (block 100) a command signal to the lock device to unlock the industrial automation device 16, thereby enabling the industrial automation equipment 16 to be placed online. After the lock device is unlocked or if the lock device is already unlocked, the processor 36 may send (block 102) a signal to a power source coupled to the industrial automation equipment 16 to supply power to the equipment 16.

The lock device (e.g., electronic lock) may be electronically controlled by the computing device 26 and/or the cloud-based computing system 28. As such, the lock device may include communication circuitry to receive and send signals, a processor to execute commands sent in the signals, and a mechanical lock that is actuated based on commands from the processor. In some embodiments, the mechanical lock may be engaged (e.g., locked) when a circuit included in the lock device is closed and may be disengaged (e.g., unlocked) when the circuit is opened by the processor of the lock device based on signals sent from the computing device 26 and/or the cloud-based computing system 28. That is, the processor of the electronic lock may receive a command signal from the computing device 26 and/or the cloud-based computing system 28 and cause the circuit to close, thereby actuating the mechanical lock into a locked position. Also, the processor may cause the circuit to open, thereby actuating the mechanical lock into an unlocked position. In some embodiments, the command signals may be sent to the lock device according to the lockout-tagout protocol.

It should be noted that the methods 50, 70 and 90 are performed using the processor 36 that is part of the computing device 26 and the cloud-based computing system 28. The computing device 26 and the cloud-based computing system 28 are configured to execute software applications that enable each device to interact with the industrial automation equipment 16. As such, the computing device 26 and the cloud-based computing system 28 are tied to particular machines, such that a tri-partite system is created to assist in the management and operations of the industrial automation equipment 16, and thus the industrial application 24. Moreover, it should be noted that the data received by the computing device 26, the cloud-based computing system 28, the industrial automation equipment 16, or the control/monitoring device 14 may be transformed when being transmitted, analyzed, or depicted for view by a user of the respective device. For example, the input received by the sensor 18 and/or the processor 36 from the display 42 or an input peripheral of the computing device 26 may be transformed into instructions displayed to the user to place the industrial automation equipment 16 offline according to the lockout-tagout protocol.

Technical effects of the embodiments described herein include coordinating the transfer of data between the computing device 26, the cloud-based computing system 28, and the industrial automation equipment 16. By efficiently sharing data between these components, operations and maintenance of the industrial application 24 may be performed more efficiently. Further technical effects may include displaying instructions to guide a technician in placing the industrial automation equipment 16 offline according to the lockout-tagout protocol when the reason provided for placing the equipment 16 offline is specified as a reason to use the lockout-tagout protocol in government regulations. Also, the embodiments disclosed herein include tracking statistics of the industrial automation equipment 16, and providing software restraints to returning the equipment 16 back to service. Although the above system and techniques are described with regard to the industrial application 24, it should be understood that the system and techniques may apply to any regulated industry, such as pharmaceutical, oil and gas, food and beverage, and so forth.

In the preceding specification, various embodiments have been described with reference to the accompanying drawings. It will, however, be evident that various modifications and changes may be made thereto, and additional embodiments may be implemented, without departing from the broader scope of the invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative rather than restrictive sense.
