PLC Assembly Instance 113 (0x71) - 240 Registers (iVu Inputs/PLC Outputs)
Data transfer direction: Originator (PLC) to Target (iVu Plus). Assembly Instance 113 (0x71) has more registers than
Assembly Instance 112. This allows for more comprehensive control of the iVu Plus, including Command Channel
functionality.
