Free connection string
To use a database with ODBC interface that is not supported by the TwinCAT Database Server by default, you can select "Unknown Database" as ODBC type.
Declaration in the TwinCAT Database Server Configurator
ODBC Free Connection String database | |
|---|---|
Database Type | "Odbc_Database" |
ODBC Type | Select "Unknown Database" from the drop-down menu. |
Simply find the connection string for the ODBC database and remodel it in the configuration window of the TwinCAT Database Server.
Two commands are available in the context menu for this purpose:
- Add additional Parameter
Adds a general parameter for the connection string. This can have any name, as required by the connection string. - Add additional Password Parameter
Adds a special password parameter, the value of which is not readable (encrypted) in the configurator and in the configuration file.
 | Operating principle with Free Connection String To ensure that the TwinCAT Database Server can work with a Free Connection String, the corresponding driver must be installed on the target system of the TwinCAT Database Server. Only "SQL Expert mode" can be used! |
