BMENOC0321 Module Characteristics

Introduction

This chapter describes the BMENOC0321 Ethernet control network module.

This module is the preferred entry point from the to a (including RIO and distributed equipment) managed by a Modicon M580 . The module provides network transparency and provides a direct Ethernet connection between the control room subnetwork and the automation devices subnetwork.

What Is in This Chapter?

This chapter contains the following sections:

control network

An Ethernet-based network containing PACs, SCADA systems, an NTP server, PCs, AMS, switches, etc. Two kinds of topologies are supported:

flat: All modules and devices in this network belong to same subnet.
2 levels: The network is split into an operation network and an inter-controller network. These two networks can be physically independent, but are generally linked by a routing device.

device network

An Ethernet-based network within a remote I/O network that contains both remote I/O and distributed I/O devices. Devices connected on this network follow specific rules to allow remote I/O determinism.

PAC

programmable automation controller. The PAC is the brain of an industrial manufacturing process. It automates a process as opposed to relay control systems. PACs are computers suited to survive the harsh conditions of an industrial environment.
