The EtherCAT network differentiates between input-connectors (IN) and output-
connectors (OUT):
At the EtherCAT slaves (communication interface modules), the ETH1-con-
nector is IN and the ETH2-connector is OUT.
At the EtherCAT master (communication module), the ETHCAT1 connector has
to be used. The ETHCAT2 connector is reserved for future extensions.
