PLC-5 Analog Inputs/Outputs

You need to identify the rack/slot/module of the actual module and then search your program for "BTR" instructions that reference that rack/slot/module. Then double-click on "Setup Screen" in the BTR instruction to open the setup dialog. The address associated with each channel should be listed there. You can then do a cross-reference or find-all for that address. For example, if I wanted to find the "ch1 vollmer" data, I would just search for N7:54:

Of course, this is the example I have handy. Your experience may vary.
