Customer has a machine circa 1988 with a Cutler-Hammer MPC1 controller that he intends to resell. He's OK with changing the PLC but wants to extract the program if at all possible. I'm trying to determine if the memory was lost. At power up, the battery and power lights come on, and the run light flashes continually. It does not seem to actually be in run as none of the outputs function. All I know is that a handheld programmer is required to access the logic, which we don't have.
Can anyone help me diagnose the meaning of the lights, or perhaps point me to a manual for this antique?
