So a few weeks ago I had an issue with the PLC clock and HMI clock going balistic and resetting to strange values on the HMI.
I now believe these issues have been resolved.
However the site have now contacted me and claim that the time has lost two hours in the three weeks since the visit! Think I have worked out roughly 30 minutes a week.
Can anyone explain this? I am using wallclock etc. etc. and as I was unsure if time was being altered at the HMI by operators I wrote a simple routing to sync the clocks at 6am and 6pm each day.
The operative who contacted me also said the PLC clock (at HMI) appeared to freeze for approx. 20 seconds...although am sure this is nothing to do with issue.
Any thoughts as I am now baffled.
