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.
