Wiring Methods

This section describes connection and disconnection of the Ethernet cable.
Connecting the cable
1.
Push the Ethernet cable connector into the RJ71PN93 until it clicks. Pay attention to the connector's direction.
2.
Lightly pull it to check that it is securely connected.
3.
Check that the SD/RD LED of the port connected with an Ethernet cable is on.
*1 The time between the cable connection and the SD/RD LED turning on may vary. The SD/RD 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. Check whether the cables are connected properly if the SD/RD LED does not turn on. ( MELSEC iQ-R PROFINET IO Device
Module User's Manual (Application))
Disconnecting the cable
1.
Press the latch down and unplug the Ethernet cable.
Precautions
• Place the Ethernet cable in a duct or clamp it. If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the module or the cable 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, this can increase transmission loss, causing a problem in communications.
• Check that the Ethernet cable is not disconnected or not shorted and there is no problem with the connector connection.
• Do not use Ethernet cables with broken latches. Doing so may cause the cables 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 damage to the module or the cable or malfunction due to poor contact.
• To prevent dust and dirt from getting in, attach an included connector cover to a connector to which an Ethernet cable is not
connected.
• For an Ethernet cable between nodes, the maximum cable length is 100m. However, the 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.
• Do not connect the PROFINET network to other networks such as LANs for general-purpose. Otherwise, a network failure
due to overload or malfunction may occur.
• Do not disconnect the Ethernet cable during operation. Doing so may cause malfunction of the module as normal data
transmission is not guaranteed.
Maintaining EMC Directive
To ensure that this product maintains EMC Directive, take the following measure.
• Use a shielded twisted pair cable to connect the Ethernet cable. Strip a part of the jacket of the shielded twisted pair cable
as shown below and ground the exposed shield with the contact surface as large as possible.
