(2) Precautions
This section describes precautions on the wiring for CC-Link IE Field Network.
(a) Laying Ethernet cables
• Place the Ethernet cable in a duct or fix the cable by clamping it. If not, dangling cable may swing or
inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.
• Do not touch the core of the connector of the cable or the module, and protect it from dirt and dust. If any oil
from hands or any dirt or dust sticks to the core, it can increase transmission loss, causing data link to fail.
• Check the following:
• Is any Ethernet cable disconnected?
• Is any Ethernet cable shorted?
• Are the connectors securely connected?
(b) Broken cable latch of the Ethernet cable
Do not use an Ethernet cable with broken latches. Doing so may cause the cable disconnection or malfunction.
(c) Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable with
connected to the module may result in damage to the module or cable or malfunction due to poor contact.
(d) Connectors without Ethernet cables connected
To prevent dust from entering the module, attach the included connector cover.
(e) Maximum station-to-station distance of the Ethernet cable (maximum cable length)
The maximum station-to-station distance is 100m. However, the distance may become shorter depending on
the operating environment of the cable. For details, contact the manufacturer of the cable used.
(f) Bend radius of the Ethernet cable
There are restrictions on the bend radius of the Ethernet cable. Check the bend radius in the specifications of
the Ethernet cable used.
