TwinCAT driver
Observe these guidelines when working with TwinCAT driver.
Supported controllers
The driver supports these controller families:
- TwinCAT® runtime
- Beckhoff ® TwinCAT® systems

The driver has been tested with TwinCAT® runtime and CX5130-0155.
Controller tags import
IMPORTANT:
Before importing tags from Beckhoff ® TwinCAT® controllers, perform Configure controller routing.
You can import tags in these modes:
- Online mode
- Use online mode to import tags directly from the controller at design time or runtime.
- Offline mode
- Use offline mode to import tags fromTPYfiles.For more information, refer to the product documentation.
This communication driver supports importing custom data types defined in the controller project.
