Rob84 Posted April 7, 2021 Report Share Posted April 7, 2021 Hello I am kinda new with ladder diagrams. So i'm am trying to read myself into the ladder functions but i can't find how I can connect a analog input value directly to a analog output, 4-20 ma measures temperature -40 to 60 degrees Celcius. Can anybody help me with this. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted April 8, 2021 MVP 2023 Report Share Posted April 8, 2021 If both the analog input and the analog output are 4-20mA and have the same bit resolution (check datasheets for the I/O modules), then simply perform a "Store" function from the integer assigned to the input to the integer assigned to the output. If there are any differences between the input and output (type of input or output, bit resolution, etc) then perform a Linearization function between the two.

Rob84 Posted April 9, 2021 Author Report Share Posted April 9, 2021 Hello Flex727 and Joe, Thanks for your reply. I managed to connect the AI to the AO, and it works properly. See attached document. Maybe you have some remarks and tips you can share. Rob Start.ulpr Quote Link to comment Share on other sites More sharing options...
