MASTER COMMS DIAGNOSTICS
Master Comms Diagnostics appears as an additional item on the System Menu. For details of the other
items see
section 4.6.
Most items are self-evident.
The Total requests and Bad requests totals both exclude retries. The numbers in parentheses are excep-
tion code numbers as described in
table 8.2.1b
.
The Initiate Comms Test is a loop-back test that sends a message to the selected slave and waits for it to
be returned. If the test is successful, the ‘Successful Comms Test’ is incremented. If not successful, one
(or more) of the error box values is incremented.
