Hi,
We have an S5 plc with cpu 944B and CP535 communication processor.CPU has EEPROM and CP535 has an EPROM.Everytime we download our back up program from our PG, 0 blocks transferred appears at the PG screen.So we pull out the EEPROM and download the program and from there the program was downloaded.We put back the EEPROM and run our plc.Now, our problem is we cannot read any message in our control console when we activate any command button just like a SAFE STOP button in our machine.Normally it sends message to our console monitor when we press SAFE STOP button at our machine.What could possibly be our problem?We checked already our cpu, cp, ethernet bus, 3com and it is working.The only thing we did replace was the EPROM because it was corrupted.When we replaced the EPROM,of course with a program in it and our plc is in run mode,still we have no communication between our machine and the plc.Also where can we find a COM 535 software english version wherein we can read and transfer programs of EPROM? PLs help..thanks.
