I have Siemens S5 6ES5 942-7UB11 fitted with a 6ES5 375-0LA21 EPROM, Analog I/O card and 6 digital I/O that crashes recently. I reboot the controls and it's ok for a few minutes then crashes again.
Since the machine was originally from germany, we have no backup copy of the program. I plugged in my computer running S5 v7.17, to upload the program and download it again, still theres error.
I've tried "Overall default/reset" procedure alot of times with the Eprom connected and still i can't get the error to go away. I tried overall reset w/out the eprom and the RUN led turns green but the programs still not responding. I called up Siemens technician and give me advice in how to transfer Eprom program to CPU ram but still theirs error.
My questions are
1. How can i get to transfer EPROM program to the CPU RAM?
2. Why my pc running STEP5 cant upload program from Eprom? The siemens tech told me that i have to upload program from eprom using the PG programmer?
3. When i uploaded the program using S5 and save it, then downloaded it again, i get memory full error during downloading? Why is that?
