I need help with serial comms from a PLC5 to an Adaptive Alpha 7120 message display. I need to know how to build the proper strings to send out of the PLC serial port to the display. Been sorting through the user manual and it doesn't look that tough but I can't seem to get it to work. I want to build the message strings in the PLC and send them to the display so it will not be necessary to go out and hook up to each sign to change canned message text. Any help will be sincerely appreciated!
