Thanks for the replies; so far we have been unsuccessful finding anyone locally with Omron experience. Schneider/Square D/Modicon are very popular here, due to the longterm French influence. I understand Omron offered nonvolatile EEPROM memory cassettes for these C200HG PLC's? Is it possible to do a program dump from the battery backed RAM to one of these nonvolatile cassettes in order to get a backup? And if so, where could I source one of these cassettes? I have an OEM P/N (C200HW-ME32K), but received no hits when it was Googled, and nothing on eBay. TIA, John
