I am on a quest to find an accurate clock in a PLC- by accurate I mean a minute or two a year. I currently use Unitronics PLC's which are accurate to +/- 1 minute per month at room temperature. Every other small PLC vendor has the same spec if they even have a clock at all. I don't have a way to communicate with the installed units so we can't reset the clock that way.
I'd like to throw this topic out and see what experience others have had.
