Wiring the EtherCAT Communication Unit

Perform the wiring for the communications cables.
Preparing the communications cables
Determine the number and length of communications cables that are appropriate for your system
configuration.
Each communications cable between the nodes (and between the master and the nodes) must be no
longer than 100 m.
In the system configuration example used in this chapter, a cable of 5 m is prepared for
communications cable 1, and a cable of 1 m is prepared for communications cable 2.Connect an RJ45
connector to both ends of the communications cable by wiring them straight. Connect both ends of the
shielded wires of the cable to the hoods.
For details on preparing the cables, refer to 2-1-6 Connection between Communications Cables and
Connectors on page 2-7.
