Technical support / Corrupt EEPROM
« on: January 05, 2009, 12:37:56 PM »
My company has been using your PLCs pretty successfully for years now and have never encountered corrupted EEPROMs. We're using the 2018 eeprom and the code is VERY large. Again, we've done every trick in the book to reduce the size of the program. As of right now, the EEPROM is at 8159 words.
Now recently we've been encountering this problem. We've always been using the same power supply and same I/O. The EEPROMs have not been damaged, we've only had to reload the programs. But we can't allow this to happen with our customers. Is there some link between the size of the EEPROM program and the frequency of program corruption? Should we really be staying below some number other than 8191 to avoid this problem?
