I have a PLC5 5/15 that use to read a level probe (4-30mA) signal from a 1771-IFE analog input card. The probe has been out of use for probably 10 years (if not more). I'm trying to reclaim the life of the AI card, but can not seem to get anything to read on the input side. Now trying to read a 4-20mA signal for IR thermocouple.
I think the configuration is right for the BTR & BTW instructions, but I'm going by the I/O configuration in the PLC. The rack is actually 7-slot rack with all the I/O in the rack. Not worried about the previous configuration (like I said, the other device died, and was never replaced).
I've done similar instruction moves with the Generic Block Transfer as the Module Type and BT registers as the Control Block, never as that 1771-IFE analog card and an integer file as the control block. Pretty sure that I have the data file set up properly (although the max scaling is a question).
I've attached the PLC I/O configuration that I found, and a shot of the PLC ladder (PLC5.JPG) that is being used. I'll attach a picture of the rack on the next post. Does anyone see my issue?
