6-10 Troubleshooting the SynchLink Module
Configuration Pop-Up Screen
This pop-up screen provides information on what module service to perform
and where to perform it. For example, you must use this screen to retrieve
diagnostic counters (module service) from the 1756-SYNCH module (where
to perform service).
The configuration portion of a message instruction requires specific
information in the fields shown above to ensure that the correct service is
performed at the module. In the case of the 1756-SYNCH module, the most
common use for a message instruction is to use diagnostic counters to
recognize a problem on the module so you may correct it.
After correcting the problem, you probably will want to reset the counters for
future use. Table 6.4 shows the values necessary on the configuration pop-up
screen to retrieve counter and to reset counters.
