Hi guys,
I have recently moved jobs and I now find myself working with antique PLCs (Modicon 984s). It's a huge jump from Allen Bradleys super ControlLogix PLCs. Anyway, I have connected the Modicon up to a PC via the Modbus network and I am now communicating to the PLC using Wonderware Intouch version 7.0. I can do most things but I am struggling with one aspect and that is the time setting. Every time that I write to the registers that contain the time, the Intouch fails to overwrite the PLC time with the time that I have entered via intouch. Has anybody out there come across this before? Are the time registers read-only?
Thanks,
Colm
