Error messages and codes

To troubleshoot Gateway Communication Driver problems, use the following error messages together with the OI Server Manager Diagnostics data. Use the Log Flag data to customize the messages logged to the Log Viewer. See the Log Viewer online documentation for more information about using log flags.

Gateway Communication Driver processes write requests by receiving them from a client, doing any necessary type conversions, and then forwarding them to the data source. The write request from the Gateway Communication Driver to the data source succeeds or fails.

In the case of write success, the Gateway Communication Driver informs the client that the write succeeded through write acknowledgement support provided by the client side protocol.

In the case of a write failure, the Gateway Communication Driver informs the client that the write failed through the same client side protocol support. In the case of write failure to items on ArchestrA, DDE, SuiteLink and InTouch data sources, OPC_E_BADRIGHTS is reported regardless of the failure reason.
