I am trying to use the Siemens S7-300 PLC system to monitor temperature changes using a two wire 100ohm platnium RTD. I am using a SM331 AI 8x12bit Analog input card, model # 331-7KF01-OABO. I am having trouble getting the PLC to read any value from the RTD, I am pretty sure that I have the connection made properly but I am completely stumped. If anyone can help please let me know.
