Appendix A.4. Panel Synchronization
Manual synchronization is required. Push the reset button on the panel. This transmits a
reset message to the FieldServer, which clears the data in the FieldServer. After a reset the
panel sends messages to report all abnormal states. When all these messages have been
processed the FieldServer and panel will be synchronized. This process can be repeated at
any time.
Appendix A.5. What happens when the panel sends a Reset Message
When a panel sends a reset message the driver processes every single Map Descriptor,
looking at the ‘Clear on Reset’ parameter (See section 4.4.2). If the parameter is set to yes,
then the driver sets all the Data Array elements referenced by the Map Descriptor to zero by
looking up the DA Name, the Data Array offset and the length. The driver also clears the
relevant sections of a Data Array specified with the DA_Bit_Name parameter.
The process can take some time. For this reason, it is suggested that you take care not to
set MD length to a value larger than necessary.
Additional considerations apply when panels are connected together in an FCI network. See
section ??????????????
Appendix A.6. Networked Panels.
The driver can processes messages and store data from multiple panels provided that:
• The panels are connected in an FCI network and the panels are configured to report
their events to the main panel
• The main panel is configured to send the node of origin in a message preceding the
event message. Consult with FCI for information on how to achieve this.
Example of message sent by a panel that is networked. The driver is dependent on seeing
the node of event origin included in parenthesis before each event message.
F.S.E.C. (Node02):
MISSING: PROJ MANG OFFICE Thermal Det L1S02 00:40:18 01/01/99
F.S.E.C. (Local):
RESET: 00:40:18 01/01/99
The main panel is identified as ‘(Local)’. The driver interprets this as Node_ID=0.
To capture events from multiple networked panels you need one Node Descriptor for each
panel with the appropriate Node_ID. Each node requires a set of Map Descriptors.
