Commissioning
The search field facilitates finding specific devices (since TwinCAT 2.11 or TwinCAT 3).
Fig. 68: Selection dialog for new EtherCAT device
By default only the name/device type is used as selection criterion. For selecting a specific revision of the
device the revision can be displayed as "Extended Information".
Fig. 69: Display of device revision
In many cases several device revisions were created for historic or functional reasons, e.g. through
technological advancement. For simplification purposes (see Fig. "Selection dialog for new EtherCAT
device") only the last (i.e. highest) revision and therefore the latest state of production is displayed in the
selection dialog for Beckhoff devices. To show all device revisions available in the system as ESI
descriptions tick the "Show Hidden Devices" check box, see Fig. "Display of previous revisions".
