I made some ladder changes at one of my customers with PLC2/16 (ser B).
I knew that EEPROM was in so I did EEPROM write porcedure using KEY SWITCH: PROG>MEM>PROG>MEM - Green or Red light supposed to come but nothing happened.
Memory protect jumper was in place.
I removed battery and old program came back - so no EEPROM writing was perfomed.
I took this EEPORM out - it is better to loose program that run old one.
Any ideas what was missing?
Just don't offer to upgrade to PLC5 - he will not do it.
Thanks.
