Ethernet Cables - Mitsubishi Electric MELSEC iQ-R Series User Manual

Ethernet cables

The following describes wiring of Ethernet cables when the RJ71EN71 or the RnENCPU (Network part) is used.
Wiring methods
The following describes connection and disconnection of the Ethernet cable.
■Connecting the cable
1.
Push the Ethernet cable connector into the RJ71EN71 or the RnENCPU (network part) until it clicks. Pay attention to the
connector's direction.
2.
Lightly pull it to check that it is securely connected.
3.
Check whether the LINK LED of the port connected with an Ethernet cable is on.
*1 The time between the cable connection and the LINK LED turning on may vary. The LINK LED usually turns on in 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. If
the LINK LED does not turn on, refer to the following and take corrective actions.
 MELSEC iQ-R CC-Link IE Controller Network User's Manual (Application)
Both P1 connector and P2 connector can be used. (Ring topology is available only when "CC-Link IE Control"
is selected as network type for P1 connector.)
• When only one connector is used in star topology, either P1 connector or P2 connector is applicable.
• When two connectors are used in line topology and ring topology, the cable can be connected between P1
and P1, P2 and P2, or between P1 and P2.
■Disconnecting the cable
1.
Press the latch down and unplug the Ethernet cable.
■Precautions
• Place the Ethernet cable in a duct or clamp them. 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 cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt
or dust is attached to the core, it can increase transmission loss, arising a problem in data link.
• Check that the Ethernet cable is not disconnected or not shorted and there is no problem with the connector connection.
• When connecting the Ethernet cable, refer to the CC-Link IE Field Network Cable Installation Manual available from the
website of CC-Link Partner Association (www.cc-link.org). The cable installation not following the contents of the manual
may cause malfunction.
• Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
• Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to the module
may result in malfunction or damage to the module or cable.
• 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 length may be shorter depending on
the operating environment of the cable. For details, contact your cable manufacturer.
• The bend radius of the Ethernet cable is limited. For details, check the specifications of the Ethernet cable to be used.
