Appendix C.2.
Driver Stats
Cheetah panels produce data messages for slave devices to consume. The type and frequency of the messages
depends on the Cheetah firmware revision.
The driver counts all incoming messages of interest as the PLC_READ_MSG_RECD statistic. Other legal messages
which do not contain the data this driver is interested in are discarded and are counted as the MSG_IGNORED
statistic.
The PLC_READ_MSG_RECD statistic is incremented once by each Map Descriptor which extracts data from an
incoming message. Thus, one incoming message and three associated Map Descriptors would cause the statistic
to increase by three (when viewed from the connection's point of view.)
The driver ignores messages 0x0100 from Cybercat panels. These lagacy messages contain contradictory
information. If the node is configured as a Cybercat panel then the driver ignores the messages and increases the
Ignored Messages stat on the connection.
Appendix C.3.
Map Descriptor Specific Errors
Some errors produced by the driver are Map Descriptor specific. They can only be seen when using the Ruidebug
program and looking at the Map Descriptor debugging screens. For more information on how to do this please
refer to the FieldServer Utilities manual.
Appendix C.4.
Multiple Cheetah Panels
Some of the broadcast messages produced by the Cheetah panel are node-less. This means that these messages
do not identify the node of origin. Unfortunately, the message this driver uses to determine zone and device
alarms is a node-less message. This limits the number of Cheetah panels per port to one. (If there were more than
one the driver would not be able to determine the node of origin.)
