Description

FIELD OF TECHNOLOGY

The following relates to a field of engineering of computer assisted programming, and more particularly a method and system for generating engineering programs which are compatible with a specific engineering environment.

BACKGROUND

Typically, an engineering project comprises a plurality of engineering programs. The engineering project is configured to control operation of a plurality of devices in a technical installation. Examples of the plurality of devices include but are not limited to, programmable logic controllers, computers, motor drivers, control units, microcontrollers, human machine interfaces, edge servers, and industrial control systems. Each of the plurality of engineering programs are configured to control operation of one or more devices of the plurality of devices in the technical installation. For efficient control of the plurality of devices, the plurality of engineering programs may have to be coded based on specific conventions and constraints that are aligned with one or more requirements of the plurality of devices of the technical installation.

Thus, the plurality of engineering programs of the engineering project may be designed to be compatible with a first engineering environment associated with the technical installation. The first engineering environment comprises information about conventions and constraints associated with coding languages, coding conventions, hardware configuration, software configurations, processing speed restrictions and memory restrictions which must be adhered to, by the plurality of engineering programs in the engineering project. In a case where a program of the plurality of engineering program does not adhere to the constraints dictated by the first engineering environment, then the engineering project becomes incompatible with the first engineering environment.

In a case where the engineering project is not compatible with the first engineering environment, the engineering project may not function in the technical installation associated with the first engineering environment. Thus, prior to deploying the engineering project on the technical installation, a code developer may have to manually modify the engineering project, to make it compatible with constraints of the first engineering environment.

Typically, the code developer manually modifies the engineering project to make the engineering project compatible with the first engineering environment. In order to modify the engineering project, the code developer may have to modify several thousand lines of code in the plurality of engineering programs in the engineering project. Thus, it becomes very difficult and time consuming to deploy the engineering project in the first engineering environment.

Further, to determine an erroneous code that is causing the engineering project to be incompatible with the first engineering environment, the code developer may have to analyze a huge portion of the engineering project, line by line. Such an endeavor may consume a huge amount of time for the code developer. Conventional engineering systems fail to automatically determine the erroneous code that is causing the engineering project to be incompatible with the second engineering environment. Hence, there are no mechanisms to automate engineering involved in generating engineering projects.

Currently, the engineering projects comprise a huge number of engineering programs, each of which are enormous in code length. Each of the plurality of engineering programs may have data and control flow interrelationships with other engineering programs of the plurality of engineering programs. Any modification of any program of the plurality of engineering program may result in a disruption in the data flow and the control flow interrelationships between the plurality of engineering programs of the engineering project. Further, the plurality of engineering programs may not be readable and understandable. To make the plurality of engineering programs readable, the code developer may have to manually enter comments, annotations, and modularize the plurality of engineering programs. It is almost humanly impossible to go through millions of codes present in the plurality of engineering programs to modularize the plurality of engineering programs.

Further, the engineering project may have a huge number of programming elements such as variables, classes, and functions which may be defined in the engineering project. In existing systems, the code developer may have to study a gigantic number of such definitions and references of the plurality of programming elements and also the control and data flow interrelationships between the plurality of engineering programs, before modifying any one of the plurality of engineering programs. It is difficult for the code developer to manually go through the huge number of engineering programs and the huge number of programming elements, as well as identify the interrelationships between the plurality of programming elements and the plurality of engineering programs in the engineering project. Furthermore, it is very difficult for the code developer to migrate the engineering program from the first engineering environment to a second engineering environment for the aforementioned reasons.

SUMMARY

An aspect relates to an efficient method and system for generating engineering projects which are compatible with a specific engineering environment.

Therefore, it is an aspect of embodiments of the present disclosure to provide a method and system for generating engineering projects which are compatible with specific engineering environment.

An aspect of embodiments of the invention is achieved by a method of generating engineering projects compatible with a specific engineering environment. In embodiments, the method comprises receiving by a processing unit, a request to convert a first engineering project which is compatible with a first engineering environment, to a second engineering project which is compatible with a second engineering environment. The first engineering project and the second engineering project comprise a plurality of engineering programs designed to control operation of a plurality of devices in a technical installation. Examples of the plurality of devices include but are not limited to, programmable logic controllers, computers, motor drivers, control units, microcontrollers, human machine interfaces, edge servers, and industrial control systems. The first engineering environment and the second engineering environment comprises information associated with a plurality of constraints associated with coding languages, coding conventions, hardware configuration, software configurations, processing speed restrictions and memory restrictions which must be adhered by the plurality of engineering programs in the engineering project. The plurality of constraints enable the plurality of engineering programs to efficiently operate the plurality of devices of the technical installation. The technical installation is at least one of an industrial manufacturing plant, an industrial processing plant, or an industrial power plant.

In an embodiment, the plurality of devices function together in the technical installation to achieve one or more objectives of the technical installation. Each of the plurality of devices comprises a processor and a memory. The memory is configured to store one or more engineering programs of the plurality of engineering programs. The processor of the plurality of devices is configured to execute the one or more engineering programs to achieve one or more key performance indicators associated with the one or more engineering programs. Examples of the one or more key performance indicators includes a processing speed, a memory requirement, and a process efficiency of the one or more engineering programs, when the one or more engineering programs are executed by the processor of the one or more engineering objects. The one or more engineering programs may be compatible with one engineering environment and incompatible with other engineering environments.

In other words, the method further comprises determining, by the processing unit, the plurality of logical blocks from the plurality of engineering projects. The plurality of engineering projects are automatically split into meaningful and logical blocks based on the data flow and the control flow between the plurality of code statements in the plurality of engineering projects. Thus, the plurality of engineering projects are thereby modularized into the plurality of logical blocks. The readability and maintainability of the plurality of engineering project is improved.

The ontology schema comprises information about relationships between the determined plurality of logical blocks, and information about data flow and control flow between each of the plurality of logical blocks of the plurality of engineering projects. In one example, the ontology schema comprises information about a correspondence between a logical block of a first engineering project of the plurality of engineering projects, and a logical block of a second engineering project of the plurality of engineering project. The ontology schema further comprises information about functions performed by each of the plurality of logical blocks in the plurality of engineering projects. The ontology schema further comprises information about compatibility of each of the plurality of logical blocks with each of the plurality of engineering environments. The ontology schema further comprises information associated with interrelationships between the plurality of logical blocks, the plurality of engineering environments, and one or more key performance indicators of the plurality of engineering programs of the plurality of engineering projects. Advantageously, interrelationships and dependencies between the plurality of logical blocks in the plurality of engineering programs are integrated into the ontology schema.

The engineering system 102 is communicatively connected to the technical installation 106 via the network 104 (such as Local Area Network (LAN), Wide Area Network (WAN), Wi-Fi, Internet, any short range or wide range communication). The engineering system 102 is also connected to the one or more client devices 120A-N via the network 104.

The engineering system 102 is connected to one or more engineering objects 108A-N.

The communication interface 208 is configured for establishing communication sessions between the one or more client devices 120A-N and the engineering system 102. The communication interface 208 allows the one or more engineering applications running on the client devices 120A-N to import/export engineering project files into the engineering system 102. In an embodiment, the communication interface 208 interacts with the interface at the one or more client devices 120A-N for allowing the engineers to access the engineering programs associated with an engineering project file and perform one or more actions on the engineering programs stored in the engineering system 102.

The input-output unit 210 may include input devices a keypad, touch-sensitive display, camera (such as a camera receiving gesture-based inputs), etc. capable of receiving one or more input signals, such as user commands to process engineering project file. Also, the input-output unit 210 may be a display unit for displaying a graphical user interface which visualizes the behavior model associated with the modified engineering programs and also displays the status information associated with each set of actions performed on the graphical user interface.

The set of key performance indicators associated with the plurality of logical blocks are key performance indicators achieved by the one or more engineering objects 108A-N, when the one or more engineering objects 108A-N executes the plurality of logical blocks of the plurality of engineering projects. In one example, the ontology schema is a knowledge graph-based representation comprising a plurality of layers.

Further, the object behavior model generation module 304 is configured for determining one or more engineering object properties associated with each of the classified one or more engineering objects 108A-N. The object properties are object's domain context, association and relationship with other engineering objects, object size, object identifier, type of engineering object, and the like. Such object properties are determined for each of the one or more engineering objects. Such determination using ontology enables engineering object elicitation & generalization, defines property & relationship between the engineering objects.

Furthermore, the analysis module 306 is configured for identifying deviation between the retrieved data and control parameters associated with the set of programming blocks and the data and control parameters stored in the object behavior model. The deviation indicates a difference between the retrieved data and control parameters, and the data and control parameters stored in the object behavior model. Also, the analysis module 306 is configured for determining type of behavior of the one or more engineering objects 108A-N corresponding to the identified deviation. The type of behavior comprises normal, abnormal, steady, and require maintenance and the like. Furthermore, the analysis module 306 is configured for analyzing the behavior of the one or more engineering objects 108A-N based on the determined type of behavior.

The modifier module 308 is configured for modifying the plurality of logical blocks based on the outcome of analysis of the ontology schema. The plurality of logical blocks is modified based on the analysis of the ontology schema. The modifications comprise any changes such as addition, deletion, update, replacement or revision of one or more variables, code lines, classes, functions, or comments in the plurality of logical blocks. In one example, an outcome of analysis of the ontology schema may be a behavior report indicating whether behavior or characteristic of each logical block of the plurality of logical blocks as defined in the ontology schema is acceptable, improvised, enhanced, optimized or the like. Thus, the plurality of logical blocks are modified based on the relationships between the set of variables corresponding to each logical block in the plurality of logical blocks, the set of Key performance indicators associated with the plurality of logical blocks, and an industrial domain of the technical installation 106. Thus, the plurality of engineering projects is generated based on the relationships between the set of variables corresponding to each logical block in the plurality of logical blocks, the set of Key performance indicators associated with the plurality of logical blocks, and the industrial domain of the technical installation 106. In other words, the plurality of logical blocks are customized based on the ontology schema, to generate a set of engineering projects which are compatible with one or more engineering environments of the plurality of engineering environments.

Further, the validation module 312 is configured for simulating behavior of the set of logical blocks in the simulation environment by executing the set of logical blocks on the generated simulation instance. The simulation environment emulates an actual technical installation, such as technical installation 106. Further, the simulation environment may be a virtual setup of the actual technical installation 106. Also, the validation module 312 is configured for validating the behavior of the set of logical blocks based on results of simulation. The results of simulation may indicate success or failure of the second engineering project if deployed in the second engineering environment.

The deployment module 314 is configured for deploying the second engineering project in real-time onto the second engineering environment based on the validation. The generated engineering program is only deployed after the determination that the generated engineering program is compatible.

The first engineering environment and the second engineering environment comprises information associated with a plurality of constraints associated with coding languages, coding conventions, hardware configuration, software configurations, processing speed restrictions and memory restrictions which must be adhered by the plurality of engineering programs in the engineering project. The plurality of constraints enable the plurality of engineering programs to efficiently operate the plurality of devices of the technical installation 106. The technical installation 106 is at least one of an industrial manufacturing plant, an industrial processing plant, or an industrial power plant.

The plurality of devices function together in the technical installation 106 to achieve one or more objectives of the technical installation 106. Each of the plurality of devices comprises a processor and a memory. The memory is configured to store one or more engineering programs of the plurality of engineering programs.

Examples of the one or more key performance indicators includes a processing speed, a memory requirement, and a process efficiency of the one or more engineering programs, when the one or more engineering programs are executed by the processor of the one or more engineering objects.

The one or more engineering programs may be compatible with one engineering environment and incompatible with other engineering environments. In other words, the plurality of constraints associated with the first engineering environment may be mutually exclusive with the plurality of constraints associated with the second engineering environment. Thus, the received request comprises an instruction to convert the first engineering project which is compatible with the engineering program to the second engineering project which is compatible with the second engineering environment. In one example, the first engineering environment is a single-user engineering environment, and the second engineering environment is a multi-user engineering environment.

The data flow indicates a transformation of values of a plurality of data variables in the plurality of engineering programs. The control flow comprises information about a sequence in which the plurality of code statements are executed by the processing unit 202. For example, the control flow comprises information about statements which will be repeatedly executed by the processing unit 202, because of the presence of looped and recursive statements in the plurality of engineering programs.

At step 408, a plurality of logical blocks is determined by the processing unit 202, from the plurality of engineering projects by grouping the plurality of statements into the plurality of logical blocks. The plurality of code statements are grouped based on analysis of the determined data flow and the determined control flow between each of the determined plurality of statements, by the processing unit 202. In other words, the plurality of logical blocks is determined by the processing unit 202 from the plurality of engineering projects. The plurality of engineering projects are automatically split into meaningful and logical blocks based on the data flow and the control flow between the plurality of code statements in the plurality of engineering projects. Thus, the plurality of engineering projects are thereby modularized into the plurality of logical blocks. The readability and maintainability of the plurality of engineering project is improved.

The ontology schema comprises information about relationships between the determined plurality of logical blocks, and information about data flow and control flow between each of the plurality of logical blocks of the plurality of engineering projects. In one example, the ontology schema comprises information about a correspondence between a logical block of a first engineering project of the plurality of engineering projects, and a logical block of a second engineering project of the plurality of engineering project. The ontology schema further comprises information about functions performed by each of the plurality of logical blocks in the plurality of engineering projects. The ontology schema further comprises information about compatibility of each of the plurality of logical blocks with each of the plurality of engineering environments. The ontology schema further comprises information associated with interrelationships between the plurality of logical blocks, the plurality of engineering environments, and one or more key performance indicators of the plurality of engineering programs of the plurality of engineering projects.
