Q. I connected a two wire RTD to the F2-04RTD but the temperature reading is way off or it reads burnout, what's wrong?
A. The F2-04RTD requires a third connection for lead length compensation. Short the CH-terminal to COM.

Q. I have programmed the multiplexing logic into my 240/250 but the data is never changing and the channel ID bits are not changing. What's wrong?
A. Most likely the pointer data for the slot your RTD module is in is not zeroed. If your F2-04RTD is in Slot 0 make sure V7660 and V7670 contain zeros, then power cycle the PLC.
