Precautions - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

■Switching hub
Use the following industrial switching hubs.
Term
TSN switching hub
General-purpose switching hub
A switching hub can be used for cascade connection.
When the switching hub is used for cascade connection, check the specifications of the switching hub used.

Precautions

• Since there are different restrictions for system configurations using a TSN switching hub and system configurations using
a general-purpose switching hub, setting with an engineering tool is required. For details, refer to "SYSTEM
CONFIGURATION" in the following manual.

• Do not configure a ring topology when modules are connected to a switching hub. Doing so causes all stations to fail and
prevents data links from being performed.
Precautions
• The bending radius of the Ethernet cable is limited. For details, check the specifications of the Ethernet cable to be used.
• Place the Ethernet cable in a duct or clamp it. Failing to do so may cause dangling cabling to swing or inadvertently be
pulled, resulting in damage to the module or cables or a malfunction due to poor contact.
• When installing a cable, do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If
natural oils from your hands, dirt, or dust becomes attached to the core, it can increase transmission loss and prevent data
link from being performed normally.
• Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling cables connected to the module
may result in malfunction or damage to the module or cable.
• Confirm that the Ethernet cable is not disconnected or shorted and that there is no problem with the connector connection.
• Do not use an Ethernet cable with a broken latch. Doing so may cause the cable to become unplugged or malfunction.
• For connectors not being connected to Ethernet cables, mount the attached cap to prevent the entry of 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 the manufacturer of the cable used.
• In a line topology, do not connect a slave station with an unset IP address or a slave station that is not in the master
station's network configuration between the master station and a slave station or between slave stations.

• Communication with the Ethernet device may not be performed depending on the specifications of the connected Ethernet
device or switching hub. If communications are not possible, reduce the communication data volume of the Ethernet
device.
