I made an emergency visit to a customer who has a Click PLC connected to a Maple Systems touch screen. Since my software is newer than the software that was originally used I had to update the program when I read it from the PLC. I had to make a minor change. When I went to write the program back into the PLC I was forced to upgrade the firmware. No I don't get any values on the Maple system OIT and I can't set any setpoints. Did my MODBUS addresses get changed with the newer version of software and/or firmware?
