ABSTRACT:
A controller can process an instruction directed to the controller itself to access data in the memory of the controller dynamically at runtime, where the data can be indirectly accessed by referencing a tag name, associated with the data and a memory space in memory, which can be included in a string tag associated with the instruction. Multiple tags, each tag associated with a respective item of data, can be located or referenced dynamically at runtime to access the respective items of data where one tag can be associated with a first structure, array, and/or scope and a disparate tag can be associated with a disparate structure, array, and/or scope, via an instruction.
