Troubleshooting Device Communications

Debugging device communications involves the following processes:

• Gathering system information about current communication status

• Analyzing the available information to identify problems

The information needed to facilitate this is available from the following resources:

• Hardware alarms

• Driver errors

• Log files (system, trace, debug and driver logs)

This information can be analyzed directly to identify problems, or you can use the Plant SCADA Kernel to perform low-level diagnostic and debugging operations.

There are also procedures you can follow to debug low-level communications protocols, such as COMx and TCP/IP.
