I am working on a 15 year old SLC500/04 system.
It is about 40 minuets slow on its internal clock, and this is displayed on the connected PV900 panel.
The customer has asked for the clock to be put right, not really an unrealistic expectation.
So have been on line, and in the 'Processor Status' , and clicked the 'SET TIME AND DATE' button.
Sure enough it pulls the correct time from my lap top, but then after a few seconds, it reverts back to its old time.
With the Key IN PROGRAM , the clock will stay updated, until the Key is switched back to RUN, at which point again the old time values are being displayed.
Is there a way of resetting and maintaining the clock ?
Thanks Richard
