3.5.6. EtherCAT Communication
The Gold Maestro is the master of the EtherCAT network and must always be the first device in
the line.
The EtherCAT Out port of the Gold Maestro should be connected to the EtherCAT In port of the
next device down the line. The Out port of the last device in line can be left open. If
redundancy is required, the Out port of the last device should be connected to the In port of
the Gold Maestro.
Note: When connecting the EtherCAT communication cable it is recommended to use CAT5e
cable.
