Firmware Revision 2.8.5 and later displays the hand/override/auto status of HOA
subpoints at the ALN panel (*
panel.
–
Firmware revisions prior to 2.8.5 will recognize the PXC Compact on P1 as an
FLN device and will not display the override status.
●
Firmware Revision 2.8.4 and later provides the ability to backup and restore the
PXC Compact database from the flash memory, in the event the PXC Compact is
reset or loses power.
–
When the PXC Compact is set to P1 Mode, database restoration from flash is
automatically enabled and 128K of memory is reserved for ISB files.
Figure 5:
P1 Mode Enhanced Field Panel Point Team
The field panel point team is a team of subpoints that are automatically created when
the field panel starts up. The point team provides a defined set of points for consistent
communication across the network.
All points in the field panel point team may be monitored by the PPCL program in the
PXC Compact on P1. The field panel team ADDRESS point (read only) is used as the
P1 address in P1 mode, and the P2 ALN address in P2 mode.
The following additional subpoints are automatically added to the field panel point team
when the PXC Compact is in P1 mode:
●
APPLICATION, DAY.NGT, and OVRD TIME, must be present in every P1 FLN
device.
●
APPLICATION is the currently active P1 application at the PXC Compact on P1.
DAY.NGT and OVRD TIME are available for user-defined use with PPCL.
●
BATT reflects the status of the lithium battery.
●
BATT2 reflects the status of the Real Time Clock. If it has lost time, the coin cell
battery is dead or missing.
●
P1 TIMEOUT reflects the current communication status between the PXC Compact
on P1 and its P1 Master Field Panel.
●
P1 TIMEOUT is the number of minutes that need to expire with no field panel
polling of the PXC Compact on P1 before the P1 COMM point is changed from
YES to NO. PPCL in the PXC Compact on P1can monitor the P1 COMM point, and
perform user desired operations.
●
YEAR, MONTH, DAY, HOUR, MINUTE, SYNC HOUR, and SYNC NOW, are used
to set and sync the time for the PXC Compact on P1.
–
These points can be commanded to set an initial time for the PXC Compact on
P1.
–
The PXC Compact on P1 clock can be synchronized with the network time by
using the SYNC HOUR and SYNC NOW points in a PPCL program and the
CRTIME resident point in the field panel that has the PXC Compact on its FLN.
–
When the SYNC NOW point is commanded to YES, the SYNC HOUR value is
copied to the HOUR point, and the MINUTE point is set to zero.
