Is the 1762-OF8 configured for "Raw Proportional"?
If so a "MOV" instruction is all you need
Source N7:4 (value 31176 = 20ma)
Destination O:2.0
A "MOV" instruction is all you need for the 1762-OF4 also
Source N7:4 ( value 31206 = 20ma
Destination O:2.0
Mickey, I used your MOV instruction suggestion. The less math calculations the better for faster execution. Please see attached screenshot. The first MOV, moves the selected speed to N7:4, the second moves the N7:4's value to 1762sc-OF8 module (did not work) and the last MOV instruction moves the value to 1762-OF4 module, which worked perfectly.
What could be wrong for module OF8 module? the module now shows a blinking indicator LED. Before including the OF8 MOV instruction it was a steady indicator LED, meaning it was fine.
