I know I deleted NC-MD, PLC-MD, etc. and I need to do that restore, but now when I turn on the machine I have nothing on the monitor, the red LED on the COM-NC is lit. I can't enter intial mode to do restore data. Intial mode it's system software, and it's in EPROM, why can't I run intial mode?

It needed a 511 card to perform the plc clear down. Pee

Programmers usually had one only and moved it around machines as necessary. Have you tried to clear the plc using the switches on the front?. It looks like a 130wb Pee
