Hardware reference
3.11.11 GX-JC03/JC06 EtherCAT Junction Slave
This is a special unit for branching EtherCAT network wiring.
Each Junction Slave has one input port and two or five output ports. The
output ports on each Junction Slave can be connected to another Junction
Slave or other EtherCAT slaves.
The following types are supported:
Slave type/name Number of ports
EtherCAT Junction 3
Slave
6
Please refer to the Instruction Manual (supplied with each slave) for
mounting and connection instructions.
Node address assignment
The node address is assigned to the Junction slave automatically, starting
from 2000. Because of the internal structure of the GX-JC06, it will get
assigned 2 node addresses: first node address for the 3 ports on the left,
second node address for the 3 ports on the right. The master or previous
slave must always be connected to the IN port: top or top-left connector. The
network is scanned in order of the port numbering. Ports can be left
unconnected.
