If the device name is entered in the search mask (A) the overview is reduced in size. Activate the check

Select this device. The configuration now consists of the "EtherCAT Device" and the single slave CU2508.
Now ensure that the function is correct by restarting TwinCAT (B) in ConfigMode and carrying out
ReloadIoDevices (press key F4). If the EtherCAT device is selected (A), the current State OP (D) and Traffic
utilization (E) are displayed in the Online tab (C). Approx. 250 CyclicFrames per second are usual in the
ConfigMode with a 4 ms cycle time; no lost frames or TXRXErrors may occur.
