Analog inputs direct to analog output in ladder


Recommended Posts


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!

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.
