Precautions on Laying Twisted-pair Cable
Basic Precautions
• Press the cable connector in firmly until it locks into place at both the hub
and the PLC.
• After laying the twisted-pair cable, check the connection with a 10Base-T
cable tester.
Environment Precautions
• The UTP cable is not shielded, and the hub is designed for use in OA
environments. In environments subject to noise, construct a system with
shielded twisted-pair (STP) cable and hubs suitable for an FA environ-
ment.
• Do not lay the twisted-pair cable together with high-voltage lines.
• Do not lay the twisted-pair cable near devices that generate noise.
• Do not lay the twisted-pair cable in locations subject to high temperature
or high humidity.
• Do not lay the twisted-pair cable in locations subject to excessive dirt and
dust or to oil mist or other contaminants.
Hub Installation
Environment Precautions
• Do not install the hub near devices that generate noise.
• Do not install the hub in locations subject to high temperature or high
humidity.
• Do not install the hub in locations subject to excessive dirt and dust or to
oil mist or other contaminants.
Hub Connection Methods
If more hub ports are required, they can be added by connecting more than
one hub. There are two possible connection methods for hubs: Cascade and
stacked.
Ethernet Connectors
The following standards and specifications apply to the connectors for the
Ethernet twisted-pair cable.
• Electrical specifications: Conforming to IEEE802.3 standards
• Connector structure: RJ45 8-pin Modular Connector
(conforming to ISO8877)
Connecting the Cable
!Caution
Turn OFF the PLC’s power supply before connection or disconnecting twisted-
pair cable.
!Caution
Allow enough space for the bending radius of the twisted-pair cable.
