:(

We have a Harland Simon PLC(CPU modle:Intella120) system that contains 4 PLCs.The PLC program use the user instruction named 'PID' to perform PID control. We have a spare CPU, but how can I transfer the source code(x80086.asm, a asm file contains user instruction ) to spear CPU? Is anyone kown? Thanks

Any suggestions? Please...

A simple search on the internet reveals that Harland Simon company used standard PLCs and relabeled them. They have a support email as follows:
