ngoc vo Posted December 28, 2018 Report Share Posted December 28, 2018 Hello everyone, I'm writing a program for the PLC to read an input from pymodbus to turn on a button. So far I have succeeded on making the command prompt communicate with the PLC but I don't know how to make it so that the PLC will recognize that signal as a command and turn on the button. Below is the sample ladder logic code I used to set it up, and a screen shot of what command i used in the command prompt. My apologies before hand for my bad writing.
