• Each Junction Slave has one input port and more than one output port. The output ports on each
Junction Slave can be connected to another Junction Slave or other EtherCAT slaves.
• The Junction Slave supports the reference clock that is required for a system configuration that
enables synchronization between slaves based on a distributed clock (DC).
• The following models are examples of some of the OMRON EtherCAT slaves.
Slave type/name Number of ports Model
EtherCAT Junction Slave 3 ports GX-JC03
6 ports GX-JC06
Precautions for Safe Use
You cannot use standard Ethernet hubs or repeater hubs with EtherCAT communications. If you
use one of these, a major fault level error or other error may occur.
Precautions for Correct Use
• The GX-JC03 and GX-JC06 EtherCAT Junction Slaves do not have hardware switches for
node address setting. The Sysmac Studio is required to set the node addresses for these
slaves. The node addresses are set to 0 by default. If you use these slaves with the default
node address, a
Network Configuration Verification Error (84220000 hex) event will occur.
• The GX-JC03 EtherCAT Junction Slave needs only one node address. The GX-JC06 Ether-
CAT Junction Slave needs two node addresses.
Additional Information
The GX-JC06 EtherCAT Junction Slave which appears to be one Unit is actually composed of
two slaves. The two slaves appear as "Main device" and "Sub-device" in the Sysmac Studio,
respectively, as shown in the figure below. The input port of Sub-device appears as "Internal
Port" in the Sysmac Studio and it is internally connected to the Main device.

Sysmac Studio
The Sysmac Studio runs on a personal computer and it is used to configure EtherCAT networks
and slaves, and to program, monitor, and debug the Controller.
