device
Details
Ethernet Unit A Communications Unit for connecting the PLC to the Ethernet net-
work.
Hub A network device that serves as a central wiring point for multiple
terminals.
Twisted-pair cable Cable consisting of four pairs of thin, copper wires twisted into a
cross cable or a straight cable. Twisted-pair cables are used for
10/100Base-T networks.
Coaxial cable Cable consisting of a central conductor surrounded (in concentric
circles) by insulation and an external conductor of braided wire. This
cable is used for 10Base-5 networks.
Transceiver A device that serves as an interface between the coaxial cable and
nodes.
Transceiver cable Cable used to connect the transceiver to the nodes.
24-VDC power supply A 24-VDC external power supply for supplying power to the trans-
ceiver through the transceiver cable.
Coaxial cable terminator
(terminating resistance)
Connected to both ends of the coaxial cable.

5-1-1 Host Types and Settings
Units that are used for Ethernet communications vary according to the type and series of
OMRON PLC used.
When connecting an Ethernet Unit, check the series and type of the PLC that it will be con-
nected to and the model of the Unit that is mounted to the PLC.
For details on the hosts that can be connected to NS-series PTs via the Ethernet, refer to Ap-
pendix 8 Standard Models.
The types of hosts that can be connected to NS-series PTs with the Ethernet and the host
settings are as follows:
