Beckhoff EtherCAT & Automation Parts: buying questions

What is the difference between a Beckhoff EtherCAT terminal, coupler and junction?

An I/O terminal performs a field signal function. An EtherCAT coupler connects a terminal station to the network, while a junction provides a network branch. Beckhoff lists EK1100 as a coupler and EK1122 as a two-port junction; they serve different roles.

What else may be needed besides the I/O module itself?

Check whether the installation also requires a terminal base, removable connector, network adapter or separate power component. Confirm each item against the station documentation and the quotation contents. An individual module should not be assumed to include a complete wired station.
