Rob84 0 Posted Wednesday at 07:19 PM Report Share Posted Wednesday at 07:19 PM 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 post Share on other sites
Flex727 279 Posted Thursday at 01:01 PM Report Share Posted Thursday at 01:01 PM 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. Quote Link to post Share on other sites
Joe Tauser 357 Posted Thursday at 09:20 PM Report Share Posted Thursday at 09:20 PM If you've already started on a program upload it to your post and we can see how you've done the I/O mapping and what model numbers you are working with. Joe T. Quote Link to post Share on other sites
Rob84 0 Posted Friday at 09:20 AM Author Report Share Posted Friday at 09:20 AM 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 post Share on other sites
