6 REPORTS
This log shows all the history of events that have taken place on the loop since the application was
started (or the log was manually cleared.) It is possible to only select certain event types to reduce
report size and improve readability. This report is available from the “Communication history” pane.
6.1.1 Communication
This is a very low level log of all communication between the PC and the loop tester hardware.
Its verbosity makes it useful only for diagnosing faults and producing very large reports.
6.1.2 Event
This will show a summarised version of the communication log indicating the beginning and
end of operations, such as retrieving analogue values. It can be mixed with the communication
log to provide an indication of what operation produced what communication data.
6.1.3 Device status
These log events simply show when a device changed state and can be used to provide a
history of the loop status over a long period of time, perhaps while a visit it each device took
place.
6.1 History log
Two flavours of log are available depending on what details you need.
The loop overview simply provides a report of all devices found on their loop along with current
status, a count of how many times each device has been in any given state and finally a summary of
the loop.
