I wish to be able to change the PLC time clock from a screen. There is a function available to set time and date in the screen but cannot find one to either set the timeclock in the PLC or at least automatically synchronise the PLC clock with the screen so they are both the same.
Have I missed something?

Hi Bob,

There are 2 SAPs, one to set time PLC >> NS and one NS >> PLC.
Check my email.

Another approach is to disregard the PLC clock and use the NS time/date registers in the PLC for any calculations. This removes the potential situation where they get out of sync.
