Description
Indicates the status of the control system when the remote head module is redundant. (Always off when
the module is not redundant.)
On: Operating as the control system (system switching enabled state)
Flashing: Operating as the control system (system switching disabled state)
Off: Not operating as a control system
Indicates the status of the standby system and memory copy when the remote head module is redundant.
(Always off when the module is not redundant.)
On: Operating as a standby system
Flashing: Memory copy being performed
Off: Not operating as a standby system and memory copy not performed
Indicates the data link status.
On: Data link (cyclic transmission being performed)
Flashing: Data link (cyclic transmission stopped)
Off: Data link not performed (disconnection)
Indicates the data sending/receiving status.
On: Data being sent or received
Off: Data not sent nor received
Indicates the error status of receive data and line. When the L ERR LED is on, the port in which the error
was detected can be checked with the L ER LED of P1 or P2.
On: Abnormal data received or loopback being performed
Off: Normal data received and loopback not performed
Indicates the station number set in the module and the module communication test result.
Station number not set: "  "
When station number is set: 1 to 120
In offline mode: ""
For indication of the module communication test result, refer to the following.

STOP Sets the remote head module to the STOP state.
When the module is in the STOP state, all output (Y) points of the remote head module turn off.
Set the module to the STOP state in the following cases:
• To stop the cyclic transmission with the master station and temporarily separate the remote head
module from the system for changeover of CC-Link IE Field system
• To perform a debug operation between modules connected to the remote head module and external
devices
• To write parameters to the remote head module
The following shows an example of a debug method with external devices using the STOP switch.
(1) Set the switch to STOP.
(2) Data transfer is stopped between the link devices of the remote head module and the devices in the
remote head module, and the devices are separated from the master station control.
(3) Perform an input/output test between the module connected to the remote head module and the
external device. Since the data transfer is stopped, the input/output status data are not sent to the
master or local station.
(4) Upon completion of the test, data are written to the remote head module and the system operation
starts.
RUN Sets the remote head module to the RUN state.
In the RUN state, the data transfer is started between the link devices (cyclic data from the master station)
of the remote head module and the devices in the remote head module.
Also, the output from the master station is output from the module connected to the remote head module.
The input from the module connected to the remote head module is input to the master station.
A connector for a USB-compatible peripheral (Connector type: miniB)
PORT1 connector for CC-Link IE Field Network. Connect an Ethernet cable.
For wiring methods and wiring precautions, refer to the following.

Indicates the port status.
On: Abnormal data received or loopback being performed
Off: Normal data received and loopback not performed
Indicates the link status.
On: Link-up
Off: Link-down
