"(S44) PLC requested action has failed"
Result when WRITE the RAM program to the EEPROM.
No pre-confirmation message first.
VERIFY fails too, seems to not hit EEPROM either.
Changing broken clip modules on 10slot backplane IC693CHS391N
Prepared workbench with spare backplane/PWR321 & NEW CPU331 IC693CPU331-CE FW=8.4 WIN98PC+LM90 6.01+IC690ACC901 cable.
At OEM machine, I can WRITE to EEPROM successfully.
CPU331 FW=8.4 also.
But on workbench, failure.
New EEPROM XICOR X28HC256P-15. JP1=2-3
Confirm, resetting fault table for missing I/O after transfer Not assigning a SNP-ID either.
Some initial thoughts or direction? I could appreciate.
Thinking try another type EEPROM or migrate the old one.
But would like to succeed at the workbench.
