Can someone direct me in the right direction about the ladder code needed to ad an ADU-204 RTD to a Modicon Micro. I have done this in the past, but it a has been a few years. Modicon used to offer all sorts of good programing example via Modfax. They still have a few good documents there but not like 4 years ago. If someone can help, it would be much appreciated.

Thank you

There is no card setup (programming) required when using the ADU204 card with a Modicon Micro and a PT100 RTD. The card has (4) 3x input registers which have a normal decimal value of 2049 to 6143 which corresponds to an input range of -200C to +850C.
