Scan card in TwinCAT

This step shows how to scan an FC1028 EtherCAT card in TwinCAT and how to create the EtherCAT masters automatically. For the scan to be successful, active EtherCAT slaves must already be connected to the interfaces of the card. Otherwise the EtherCAT telegram from an inactive slave is not answered and the EtherCAT master is not created in TwinCAT.

You should have completed the hardware configuration, so that the scan runs successfully and all EtherCAT masters and the EtherCAT slaves connected to them are created in TwinCAT.

Proceed as follows:

1. Start TwinCAT and open an empty project.

2. In the tree view on the left, right-click on I/O Devices.

3. Click in the context menu on Scan.

In this example two EtherCAT masters are found because active EtherCAT slaves are connected to them.

Devices that are actually available are always available for selection.

5. Confirm the request with Yes, in order to look for boxes.

6. Confirm the request whether to enable FreeRun with Yes.

The FC1028 card has been scanned successfully in TwinCAT and is displayed with the available EtherCAT masters.
