Troubleshoot

This chapter describes troubleshooting tools you can use to deal with the ABTCP Communication Driver problems you may encounter.

The OI Server Manager provides access to diagnostics and other statistical data, and the Log Viewer provides access to event messages logged during the operation of a Communication Driver. Also, your client (for example, InTouch) can monitor connectivity with the PLC through the $SYS$Status item. Use these tools together with the information in this section to troubleshoot your ABTCP Communication Driver.

Note: In order to determine the version of your Communication Driver, the following steps need to be performed. Search for DASABTCP.dll, right-click on the File Name, select Properties on the shortcut menu, and select the Version tab on the Properties dialog box. The version of your Communication Driver is listed under File Version.

• Monitor connectivity status with the PLC

• Monitor the status of Communication Driver conversations

• Error messages
