(2) Twisted pair cable
Specifications of cables that can be used for connection with peripherals by using the user Ethernet ports (CH1
and CH2), system Ethernet port (S CH1), and Built-in Ethernet ports (CH1 and CH2) are described in the table
below.
Cables conforming to the IEEE802.3 10BASE-T/100BASE-TX/1000BASE-T standards can be used.
Unshielded twisted pair (UTP) cable,

Category 5e or higher
In the high-speed communication (100Mbps/1000Mbps) by 100BASE-TX/1000BASE-T connection, a communication error
may occur due to high frequency noise generated from a device other than the C Controller module, depending on the
installation environment.
When configuring a network system, take the following measures on the C Controller module side to eliminate the influence
of high frequency noise.
• Wiring
Do not install the twisted pair cables together with the main circuit lines or power cables.
Place the twisted pair cables in a duct.
• Cable
In an environment where the system is susceptible to noise, use shielded twisted pair (STP) cables.
• Retry processing
In an environment where the system is susceptible to noise, include the retry processing in the user program.
• Data transmission speed
Change the destination device to connect with the C Controller module from 100Mbps and 10Mbps changes the
data transmission speed for communication.
