Re-Scan and Change Coupler/Slice Associations

Coupler or slice associations must be updated after the following actions.

  • Changing the physical network topology by adding, moving, or removing I/O slices attached to an EtherCAT coupler
  • Changing the associations between physical and project I/O slices.

To update the associations:

  1. Re-scan and re-discover the physical network topology.
  2. Click the Modify button to expand the Discovered Devices and Modules view.
  3. Drag-and-drop the project coupler and/or slice(s) to associate them with the physical couplers/slices.

  • After changing the association of an EtherCAT device, you have to recompile the project and download this new version to save your modifications on the target.
