Create a Mainline Program to Update Time-Date Local Variables on
each Pass Through PPCL
NOTE:
• The PXC Compact on P1 YEAR, MONTH, DAY, HOUR, and MINUTE resident
points can be used to read and set the current time from the host field panel.
• In P1 mode, these points can only be commanded to the following ranges: YEAR
(2000 to 2058), MONTH (1 to 12), DAY (1 to 31), HOUR (0 to 23), and MINUTE (0 to
59).
• The host field panel does not itself have year, hour or minute resident points. Its
CRTIME is evaluated only once per pass to prevent rollover errors.
• There is not a SECOND point to avoid generating too many COV’s as the time
changes at the PXC Compact on P1 every second.
• Local variables are assigned for clarity instead of $LOCn.
