Synchronizing System Time in a PXC Compact on P1

● System time in the PXC Compact on P1 can be synchronized daily by the host field
panel.
● The resident P1 points SYNC HOUR (value of 0 to 23) and SYNC NOW (value of
ON or OFF) can be commanded by the host field panel over the FLN.
For example, if the SYNC HOUR point is commanded to 2.0, when the SYNC NOW
point is commanded to ON, the time at the PXC Compact on P1 will be set to 2:00 a.m.
Note that the SYNC NOW point is automatically reset to OFF by the PXC Compact on
P1 once it syncs its time.
Add Mainline PPCL to Call a Subroutine for each PXC Compact on P1
Hosted to Synchronize Time Once Daily
