If the user leaves the expert operating mask 70 and returns to the basic operating mask 10, the user can automatically be logged out. After a certain time (adjustable), the device can also automatically return to the basic operating mask 10 or to basic mode. The operating device can be configured to switch into basic mode after a restart of the machine or an interruption of the power supply.

FIG. 8 shows a list 140 with possible notifications that comprise messages triggered by the system to the user and appear if a user interaction or information of the user is required. There are three significant types of notifications. Alarms are triggered in the event of severe problems, which possibly require or cause a machine stop. Warnings are triggered in the event of problems that may cause an alarm if no action is triggered. Information relates to non-critical notifications that may inform the user about future intervention requirements.

The handling of notifications functions similarly on the basic operating mask 10 and on the expert operating mask 70; only the level of detail varies. Notifications may be handled via four elements. A first element relates to an in-context notification symbol (e.g., warning symbol on the machine model, see FIG. 2). A click on the symbol opens the notification detail as an overlay. A second element relates to a notifications button 83 in the header 80 with the last or most important notification. A click on the region opens the notifications list 140. A third element refers to a notifications list 140 that contains all pending notifications that require user assists (i.e., alarm, alerts, service). A click on one of the notifications opens a notification detail as an overlay. A fourth element relates to the illustration of a notification detail as an overlay with detailed information on the notification (e.g., HTML extract from the user manual for this type of notification) along with options for solution and direct access to the full user manual.

The elements of the basic operating mask 10 and/or the expert operating mask 70 may depend on an authorization of a user or an authorization level of a user.

In one embodiment, it can be provided that only one user can be authorized to operate a textile machine T1, T2. A read-only mode can nevertheless be available for other users. The read-only mode can be displayed in the relevant operating device on the basis of a coding, e.g. via a colored frame and/or by marking a switch area.

In one embodiment, a handshake procedure can be provided so that a user can take over the authorization of an authorized user. For example, a corresponding message that another user wishes to take over the authorization can be displayed to the authorized user. The authorized user can respond by confirming the authorization of the other user and sending his own authorization or by denying the authorization of the other user and maintaining his own authorization. It can be provided that, after a predetermined time interval, a user can take over the authorization even without reaction of the authorized user, for example if the authorized user is no longer found in the operating device. The handshake procedure can be dependent on the authorization levels of the users concerned, wherein a user with a lower authorization level being able to trigger the handshake procedure against a user with a higher authorization level can be blocked. A user who triggers the handshake procedure can be shown the user by whom the authorization is taken over, wherein the user can cancel the handshake procedure if necessary. If necessary, a user can reject the taking over of authorization for a certain period of time or for a certain number of requests, after which the taking over of authorization can no longer be rejected.

In one embodiment, it can be provided that a higher priority is assigned to an operating device 91, 92 of a relevant textile machine T1, T2 than other operating devices 91, 92, 9Z, 9M, wherein a user of the relevant operating device 91, 92 takes over the authorization of a remote user originating from another operating device 91, 92, 9Z, 9M even without the specified handshake procedure. It can be provided that it is displayed to the local user that a remote user is authorized and that a confirmation to cancel the authorization of the remote user is required by the local user.

In one embodiment, it can be provided that the operation by remote users is restricted or blocked. This can be designed in a configurable manner and can be dependent on the following: which operating devices 91, 92, 9Z, 9M are involved, whether the local or remote user has selected basic mode or expert mode, etc. For example, it can be provided that a cleaning control such as UNlcontrol can be operated only by a local user of an operating device, while this is blocked for a remote user. For example, it can be provided that alarms may only be confirmed by a local user, while alarms may be displayed to a remote user, but a confirmation for the remote user is blocked. For example, it can be provided that alarms may be confirmed only at the operating device 9Z of the control center, but not on the operating devices 91, 92 of the first or second textile machine T1, T2. For example, it can be provided that the transfer of predetermined settings / files from the operating device 9Z to the spinning mill control center Z on an operating device 91, 92 of the first or second textile machine T1, T2 or on control devices S1, S2, S3 of the textile machines T1, T2, T3 is independent of the authorization of a user, wherein the activation of relevant settings / files requires an authorized user. Such settings / files may refer to user settings, shift settings, recipe settings, etc.

In one embodiment, it can be provided that the remote transmitting function and/or the remote receiving function of the operating devices 91, 92, 9Z, 9M can be deactivated. For example, in the case of service work on the first textile machine T1, the remote receiving function of the operating device 91 of the first textile machine T1 can be deactivated in order to prevent a disruption of the service work by a remote user. By way of example, the deactivation of the remote transmission function and/or the remote reception function can be dependent on the operating devices involved. Thus, for example, the remote receiving function of the operating device 91 of the first textile machine T1 can be deactivated for the operating device 92 of the second textile machine T2, while the latter is still activated for the operating device 9Z of the spinning mill control center Z.

In one embodiment, it can be provided that a remote user is assigned a higher authorization level than the local user, such as a shift supervisor, wherein the remote user can put the local user, for example a less experienced operator, into read-only mode or basic mode, and enable operation in expert mode, whereby mutual warning messages may be provided.

In one embodiment, it can be provided that a local user can reset all other authorizations of other users after authorization, for example, so that an urgent action detected on the machine can be taken or a malfunction/faulty setting that may not be detected by a remote user can be corrected.

In one embodiment, it can be provided that the spinning mill control center can be assigned a highest priority and the authorization of a local or remote user of an operating device can be reset to completely take over the operation of a textile machine.

In one embodiment, it can be provided that a user is granted access to extended information / settings of a relevant machine after the authorization, wherein the change of information / settings can be restricted or can be completely released.

In one embodiment, it can be provided that the operating devices may assume a standby mode, for example after a time interval has elapsed without operation by a user, wherein no or limited information / settings of the machine are displayed. After a user is authorized, access to information / settings of the machine may be dependent on an authorization level of the user, in particular also depending on whether the user selects basic mode or expert mode, wherein advanced access can be granted in expert mode to make changes to information / settings.

In one embodiment, it may be provided that the operation of a textile machine is taken over by a software application, such as ESSENTIAL, wherein a local or remote user is warned if necessary or is offered the option of preventing or restricting operation by the software application.
