EtherCAT Features

• The EtherCAT network is independent of the two Modbus networks.
• The EtherCAT network supports a maximum of 512 bytes of input and 512 bytes of output.
• The EtherCAT network can cascade EtherCAT slave stations.
• The synchronization type of the EtherCAT network is FreeRun.
• EtherCAT supports CoE mailbox service and complies with CiA301.
