Error Diagnostics
There is – even with all coverage – always the possibility, that a connection doesn´t “work”. In most cases, these are not real errors, but only trivia, which can show while connecting foreign systems. In the following we collected several snares – and are always thankful for additions and hints.
Hardly any problems show, if router, OPC- and data base server run on the same computer. In the distributed system the right DCOM configuration is important for the OPC server, data base server allow or forbid even the remote access.
Note: Use in any case the tests offered in the management: “Test Connection” for the data base access data and “Test” for the mail server access. The OPC link works, if you can browse the OPC server in the management (see below). Please note, that configuration and service may run under a different user context and act differently.
In the Basic Set Ups the log levels “Error” and “Warning” should be activated as recommended. In case of a runtime error, call the log data with the tray icon and analyze the error message.
