Configurable mode model

A method for configuring ownership arbitration for an industrial control system, comprising:

• receiving, by an industrial controller comprising a processor that executes an industrial control program, mode model configuration input defining a modification to a default mode model used by the industrial controller to arbitrate between program requests generated by the industrial control program and operator requests received from a human-machine interface for control of an aspect of the industrial control program, wherein
• the mode module configuration input comprises an indication of one or more ownership modes to be included in the modified mode model and transition conditions for transitioning between the one or more ownership modes, and
• the ownership modes comprise at least one of a Program mode that allows program control of the aspect of the industrial control program, an Operator mode that allows human-machine interface control of the aspect of the industrial control program, a Program Locked mode that locks program control of the aspect of the industrial control program, and an Operator Locked mode that locks human-machine interface control of the aspect of the industrial control program;
• modifying, by the industrial controller, the default mode model in accordance with the mode model configuration input to yield a modified mode model;
• receiving, by the industrial controller during runtime, one of a program request generated by the industrial control program or an operator request from the human-machine interface for control of the aspect of the industrial control program;
• and
• arbitrating, by the industrial controller, between the one of the program request or the operator request based on the modified mode model, wherein the arbitrating comprises assigning control privileges for the aspect of the industrial control program to a selected one of the industrial control program or the human-machine interface.

A non-transitory computer-readable medium having stored thereon executable instructions that, in response to execution, cause an industrial controller comprising a processor to perform operations, the operations comprising:

• executing an industrial control program that facilitates control of industrial devices;
• in response to receiving mode model configuration data defining a change to a default ownership mode model, modifying the default ownership mode model in accordance with the mode model configuration data to yield a modified ownership mode model, wherein the mode model configuration data defines ownership modes to be included in the modified ownership mode model and commands for transitioning between the ownership modes, and the ownership modes comprise at least one of a Program mode that allows program control of a portion of the industrial control program, an Operator mode that allows human-machine interface control of the portion of the industrial control program, a Program Locked mode that locks program control of the portion of the industrial control program, and an Operator Locked mode that locks human-machine interface control of the portion of the industrial control program;
• and
• arbitrating, during runtime based on the modified ownership mode model, between program ownership requests for the portion of the industrial control program and operator ownership requests for the portion of the industrial control program received from a human-machine interface communicatively connected to the industrial controller,
• wherein the arbitrating comprises selecting one of the industrial control program or the human-machine interface for control of the portion of the industrial control program based on the modified ownership mode model.
