receive and process P1 request messages from an APOGEE tool, such as WCIS,
connected to the HMI port.
See the section Minimum Firmware Revision Required for information on the firmware
revision required to implement PXC Compact operation on P1 FLN.
P1 Mode Operation
● Since an ALN network connection is not present in P1 mode, PXC Compact
applications that support point access across the ALN are limited to local points
only.
● In P1 Mode, the PXC Compact, since it emulates an FLN device itself, does not
communicate with any other FLN devices. Thus, all of the FLN device prompts at
the HMI will be hidden. See the
Field Panel User's Manual (125-3000) for more
information.
● HMI prompts have been added to display APOGEE P1 point information. When in
P1 mode, the HMI prompts to display APOGEE P2 point information are still
available.
● If switching from P2 to P1 mode, or changing the active P1 Application, the PXC
Compact deletes its database in flash.
● Because the point team and hardware capabilities are different, applications
created for a PXC-16 cannot be used on a PXC-24 and vice-versa.
● PXC Compact on P1 displays as a TEC to ALN field panels and Insight software. It
is compatible to all APOGEE revisions of firmware and software.
● Firmware Revision 2.8.5 and later displays the hand/override/auto status of HOA
subpoints at the ALN panel (*
x *). The HOA status will be reported to the ALN level
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.
