Appendix B.1. 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.
