Systems and methods that facilitate management of add-on instruction generation, selection, and/or monitoring during execution

摘要

The subject invention relates to systems and methods that facilitate display, selection, and management of context associated with execution of add-on instructions. The systems and methods track add-on instruction calls and provide a user with call and data context, wherein the user can select a particular add-on instruction context from a plurality of contexts in order to observe values and/or edit parameters associated with the add-on instruction. The add-on instruction context can include information such as instances of data for particular lines of execution, the add-on instruction called, a caller of the instruction, a location of the instruction call, references to complex data types and objects, etc. The systems and methods further provide a technique for automatic routine selection based on the add-on instruction state information such that the add-on instruction executed corresponds to a current state.

主权项

1. A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause at least one device including a processor to perform operations comprising:
obtaining a value of a state parameter associated with an add-on instruction called by a user program executing via an industrial device in relation to an industrial process, wherein the value is a post-scan state to establish post-conditions associated with the execution of the add-on instruction; determining control logic to execute by the add-on instruction based on the value of the state parameter; and initiating execution of the determined control logic; and creating respective contexts associated with each execution of a plurality of executions of the add-on instruction, wherein the each context tracks a call to the add-on instruction, an initiator of the call, a location of the call, a passed reference to a complex data type associated with the add-on instruction, a passed reference to an object associated with the add-on instruction, and an instance of data of the add-on instruction.
