Wiring

This section describes wiring for when CC-Link IE TSN 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 Motion module 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 Ethernet port connected with an Ethernet cable is on.
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 Motion Module User's Manual (Application)
[RD78GH]
Both P1 and P2 can be used.
• When only one of P1 and P2 is used in star topology, either P1 or P2 is applicable.
• When both ports are used in line topology, P1-P1, P2-P2, and P1-P2 connections are acceptable.
■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 TSN 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 100 m. 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.
• In line topology, do not connect the slave station with no IP address setting between the master station and slave stations,
or between slave stations. Data link may not be performed between the master station and the slave stations that is
connected after the slave station with no IP address setting. However, if the slave station with no IP address setting is
connected at the end of line topology, this case is not applicable.
