180 EST iO64 and iO500 Technical Reference Manual
Diagnostics reports
There are two Diagnostics reports designed to show the
communication performance of the devices on a loop.
Comm Retries report
This report allows you to display a list of devices that have required
two, three, or four consecutive communication poll retries. It lists the
devices that could potentially generate a communication fault by
showing the maximum number of retries for the current hour and a
summary of the past 24 hours.
The report can be used to identify devices with intermittent
communication faults. A device appearing in this report is an
indication that the wiring to the device is suspect. To investigate
problem devices, inspect the wiring between the problem device
and another device not in the report. Inspect this section of wiring
for problems such as loose connections and intermittent wiring
breaks.
Note: The current hour retries can be cleared and updated by
running the Loop Comm Check diagnostic (see "Loop comm check"
for more information).
Response Quality report
This report allows you to enter a quality percentage value, which
then lists the devices that are communicating at that level or below.
By entering different percentages, you can troubleshoot device
communications on a loop.
The panel periodically stores the measurement of the response for
individual devices during communication polling. The report displays
the result of the latest poll as a percentage, where 100% is the best
response (maximum possible pulse strength) and anything less than
44% means that the device failed a communication poll and could
potentially generate a communication fault.
Devices appearing in this report are an indication that the wiring to
the devices is questionable or that the devices themselves are
questionable. To investigate problem devices, inspect the wiring
between the problem device and another device not in the report.
Inspect the wiring for problems such as exceeding wiring
specifications (see "Device loop wiring" for more information), loose
connections, and intermittent wiring breaks and shorts.
Notes
• You must have a printer connected to your panel to print a
report.
