Diagnostics reports

There are two Diagnostics reports designed to show the communication performance of the

devices on a loop.

Comm Retries report

This report lets you 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” on page 176 for more information.)

Response Quality report

This report lists the devices that are communicating at or below a quality percentage that you

specify. 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 “Addressable device loop wiring” on

page 12 for more information), loose connections, and intermittent wiring breaks and shorts.
