Figure 8-19: Message counters dialog box
The message command appears in the left column, followed by
the number of times it has been issued, the number of errors
received after the message was issued, and the percentage of
correct responses. During normal operation, the percentage of
messages received correctly should exceed 99%.
Intermittent device or wiring problems are indicated by a low
successful message rate. If successful message rates are tracked
over time, one can generate base line information for each
circuit. From the base line information, any changes from the
norm can be quickly identified, and preventive measures taken,
before a communication problem develops. Table 8-36 lists the
messages sent and received by the Signature driver controller
module.
