2 Installing the NB Unit and Connecting Peripheral Devices

NB-series Programmable Terminals Setup Manual(V107)
2-5 FINS/UDP Communication Connection
This section describes how to connect the PT with the Host through the FINS/UDP protocol.
Note OMRON Ethernet UDP communication protocol, both CJ/CS Series and CP Series, are FINS/UDP protocol.
The difference between these two protocols is only in the address range of the channel.
To connect to the network using Ethernet, the network number, node number, and IP address must be
set. Use the NB-Designer to set the settings. (The default IP address of HMI Unit is 192.168.250.1.)
Connecting PT Directly to the Host
Connect the NB to the host using twisted-pair cable.
Connecting PT to Host with a Hub
Multiple NBs and hosts can be connected using twisted-pair cable and a hub.
The Ethernet FINS communication for NB series products is only limited the
local network, but the Ethernet communication cross the network segment is
allowable with the prerequisite of using the router. That’s to say, the
supported FINS network is only limited to the local network, but the various
devices in the network can be cross the network segment. Please take the
following architecture as reference.
