1. Ethernet Port Overview

1.1 System Configuration Using the Ethernet Port

This section describes the systems that can be configured using the PU235N/245N Ethernet Port
for the PROSEC T2N programmable controller. The remainder of this document refers to the
PROSEC T2N programmable controller as the T2N, and the Ethernet Port as the PU235N/245N
Ethernet Port.
The Ethernet Port is a communication port for connecting a T2N system to a 10BASE-T (Twisted
pair Ethernet) LAN (local area network). It is operated a T2N option module. The T2N connects
to the above mentioned LAN through the Ethernet Port and exchanges data with host computers
(workstations or personal computers) or other programmable controllers on the LAN.
The remainder of this section presents a system that uses the Ethernet Port. In this example, the
T2N is connected to host machines such as workstations and personal computers over a 10BASE-
T LAN and the T2N is connected to lower level controllers using a Toshiba proprietary control
LAN.
