Wiring
The CB-EP100 uses the power supplied to measuring instrument, so there is no
power cable wiring. This section describes the wiring of communication cables used
by the CB-EP100.
Use the following procedures to connect the CB-EP100 to the communication cable
required for EtherNet/IP communication.
„ Usable cable
Usable cables depend on whether the system is configured with 10BASE-T or
100BASE-TX.
Structuring a 10BASE-T system
When the system is configured
with 10BASE-T, use a Category
3 or higher shielded twisted-pair
(STP) cable or an unshielded
twisted-pair (UTP) cable.
Building a 100BASE-TX network or better 5e
Use STP or UTP cable category 5e or better to configure a network using
100BASE-TX. Do not use a Category 3 or Category 4 cable.
• Use an STP/UTP straight cable when connecting the CB-EP100 to an
Ethernet switch.
• Use a STP/UTP cross cable when directly connecting the CB-EP100 to
a PC or PLC.
• Do not use the STP/UTP cross cable incorrectly because it is difficult to
distinguish this cable from the STP/UTP straight cable in appearance.
• Use of 1000BASE-T Ethernet cable will not make it possible to configure
a 1000BASE-T network.
