EtherCAT Master

For each infeed line an EtherCAT master is required among the I/O objects. You may use four EtherCAT masters under one Real-Time Ethernet adapter. If you use more than four EtherCAT masters, you have to add another Real-Time Ethernet adapter to the I/O objects.

Expand Solution Explorer > TwinCAT Project > I/O
Right-click on Devices to open the context menu
Click Add New Item... in the context menu
EtherCAT Master 2:

The Insert Device dialog box opens.

Expand EtherCAT
Select EtherCAT Master
If required, enter a name for the EtherCAT Master in the Name input field.
Confirm with OK

A Device (EtherCAT) is added to the I/O objects.

A CU2508 Ethernet port and the modules of an infeed line must be added to the EtherCAT master.
