Technical support / Re:Corrupt EEPROM
« on: January 08, 2009, 09:47:20 AM »
Actually, we have been burning in the same PLC for another three days after having to reload the program.  This morning we found the PLC energized, but the watchdog timer had tripped out.  We couldn't get it to respond to any command, even IR* using TLServer.

When we cycled the power it went right back to normal operation.  We've pulled that particular EEPROM and are downloading a program into a new one and commencing with burn in.

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?

Technical support / COMM3 LED useful for diagnostics?
« on: April 15, 2007, 11:39:08 PM »
Can anyone tell me if the COMM3 LED has some useful diagnostic purpose?  I have a system that has always funtioned and has two slaves connected to a single MD2424 processor.

Thanks.

Can you tell me if the TL5 Uploader program uploads the Save_EEP information as well as the machine code?
