Wiring Method

This section describes how to connect and disconnect the Ethernet cable.
Connecting the cable
1.
Turn the power supply of FX5-ENET (CPU module) and external device off.
2.
Push the Ethernet cable connector into the FX5-ENET until it clicks. Pay attention to the orientation of the connector.
3.
Lightly pull the connector to check that the connector is securely connected.
4.
Turn the power supply of FX5-ENET (CPU module) and external device on.
5.
Check whether the SPEED LED of the port connected with an Ethernet cable is on.
*1 The time between the cable connection and the turning on of the SPEED LED may vary. The SPEED LED usually turns after a few
seconds. Note, however, that the time may be extended further if the link-up processing is repeated depending on the status of the
device on the line.
Disconnecting the cable
1.
Turn the power supply of FX5-ENET (CPU module) off.
2.
Unplug the Ethernet cable while pressing the latch connector down.
Precautions
• Place the Ethernet cable in a duct or clamp it. If the cable is not placed in a duct or secured with clamps, the cable may
swing, drag or be carelessly pulled, and the module or cable may be damaged, or cable contact failure may cause
malfunction.
• Do not touch the core of the cable-side or module-side connector, and protect them from dirt or dust. If oil on your hands,
dirt, or dust adheres to the core, transmission loss may increase, causing communication problems.
• Check that the Ethernet cable is not disconnected or not shorted and check that the cable is connected properly.
• Do not use Ethernet cables with broken latch connectors. Doing so may cause the Ethernet cables to be disconnected or
the module to malfunction.
• Hold the connector part of the Ethernet cable when connecting and disconnecting it. Pulling the cable connected to the
module may result in damage to the module or the cable or malfunction due to poor contact.
• For connectors without Ethernet cable, attached connector cover should be placed to prevent foreign matter such as dirt or
dust.
• The maximum station-to-station distance of the Ethernet cable is 100m. However, the acceptable length may be shorter
depending on the environment where the cable is used. For details, contact the cable manufacturer.
• The bending radius of the Ethernet cable is limited. For details, check the specifications of the Ethernet cable to be used.
