Error messages, trace messages, error codes, and warnings

In addition to the SIDirect Communication Driver error and warning messages, S7 Trace messages and generic Communication Driver error codes are supported. Use these messages together with the OI Server Manager Diagnostic root data to troubleshoot SIDirect Communication Driver problems.

Note: The logger messages use the following codes: %s to represent strings, %d to represent numbers (integer), %x to represent the address of the object, and %ums to represent time in milliseconds.

You can also use the Log Flag data to customize the type of messages logged to the Log Viewer. For more information about using log flags, see the Log Viewer online Help.
