Hi All I purchased a new V1210 for a customer and have been developing a chunky bit of code to drive 64 pumps in various modes. The date time is becoming reset to 1st Jan '06 It also only happens on power cycle, not on reset or when downloading new code. I've checked all the obvious stuff: 1. Put in a new battery 2. Checked the battery status bit is fine (in fact I've built in a small piece of code that checks it if is set and the plc starts beeping and a battery icon flashes) until the user presesses confrm at which point I do a reset. Either I hadnt noticed or it has only started happening recently (about a month into development) - I reckon its the first option though; I have just started working on the shcedule bit that triggers on time so ony now am I paying attention to the time. Any thoughts anyone? Could I somehow be inadvertently triggering some state that resets the date/time? Many thanks Mal
