Chapter 1 Ethernet Module
(EN311) Overview
1.1 Introduction
This guide describes how to handle the Ethernet Module (EN311) for the programmable
controller, PROSEC T3H, when it is used in the Sequence Control Module S3 of the
Integrated Controller V series model 3000.
Hereafter, the Sequence Control Module S3 of the V series model 3000 is called the S
controller and the Ethernet Module for PROSEC T3H is called the EN311.
EN311 is "the transfer module of the V series model 3000 parallel I/O module" which is
installed and used on the parallel I/O bus (called the G3 bus hereafter). The S controller
transfers data to the higher LAN level devices such as workstations/PCs and other
programmable controller via the EN311. The EN311 can be connected to the LAN (Local
Area Network) 10BASE5 (Ethernet) or 10BASE2 (Cheapernet). 10BASE5 or 10BASE2
can be selected by the switch on the module.
The following is a LAN configuration example using the EN311. In this example, the S
controller is connected to host machines such as workstations and personal computers
over a 10BASE5 or 10BASE2 LAN while the S controller is connected to lower level
controllers using a Toshiba proprietary control LAN.
