I am using 1794 equipment. I have a P13 power supply as the first module, a ASB mooule then a 1794 IF4FI analog input module. My question is, in the AB scheme of things, R/G/M, which is the input module, 0, 1 or 2?
Think of things from the 1794-ASB's perspective: The analog input module is Group 0, Slot 0.
The power supply isn't addressable.
You're going to need to understand the configuration and data block transfers for this module based on which controller you've connected it to. Are you using a PLC-5, an SLC, or a ControlLogix ?
