I have a PLC 5 with a 1771-IFE analog input. I have a temperature transmitter wired to it. It converts 1000 ohm RTD signal into an analog output and has a range of -58 to 122 F. I am not sure what instruction(s) to use in my logic to get a farhenheit reading, which I will display on an HMI using Factory Talk. I tried a CPT instruction in which I multiplied the output value with a max range and divided that by 4095. No luck. I tried different max values with no luck. Thanks for any help. I am not a trained programmer, just an electrician moonlighting.
