4.1 EtherCAT cable redundancy
EtherCAT cable redundancy can be realised in the CX20x0 systems through the two independent Ethernet
ports. Minimum requirements:
1. EtherCAT redundancy supplement
2. EK1110 (Bus extension)
3. EK1100 (Bus Coupler)
The supplement product on the Beckhoff website at
http://download.beckhoff.com/download/Software/TwinCAT/TwinCAT2/Supplement/
TwinCAT_EtherCAT_Redundancy/Install/TcEcRedundancy.exe
can be downloaded. The required licence key can be ordered from our sales division. The required couplers
are ordered together with the other hardware. These components can then be used to configure the
controller. The upper figure shows a minimum configuration example for cable redundancy. Once the
hardware has been wired and commissioned, the supplement must be installed on the device, for example
via a USB stick or the IT network. During the installation the system asks for the licence key. The cable
redundancy can be set up in the System Manager. The first step involves reading the terminal configuration.
Then select "Advanced Settings" under the "EtherCAT" tab in the EtherCAT device properties. The second
adapter can be set under the "Redundancy" menu. Use the "Search" button to open the selection menu.
Select "Local Area Connection 2 (Intel(R).....)" for the lower network connection (X001). Click "OK" to
complete the configuration.
