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 CitectSCADA 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.
