GE CPU372 374 Ethernet

GE CPU372 374 Ethernet

Overview

The Series 90-30 CPU374 PLUS and CPU372 PLUS have a built-in enhanced Ethernet  interface that provides TCP/IP communications with:  

▪ Series 90, PACSystems, and VersaMax PLCs  

▪ host computers running the Host Communications Toolkit or CIMPLICITY software  

▪ computers running the TCP/IP version of the programming software.

CPU372 PLUS and CPU374 PLUS Ethernet Features

▪ Full PLC programming and configuration services  

▪ Periodic data exchange using Ethernet Global Data (EGD)  

▪ EGD Commands to read and write PLC and EGD exchange memory over the network  

▪ TCP/IP communication services using SRTP  ▪ Support for SRTP Client (Channels)*  

▪ Modbus/TCP Server, supporting Modbus Conformance classes 0, 1, and 2.**  

▪ Modbus/TCP Client, supporting Modbus Conformance classes 0, 1, and Function  Codes 15, 22, 23, and 24 for Conformance class 2.**  

▪ Basic remote PLC monitoring from a web browser*  

▪ Comprehensive station management and diagnostic tools  

▪ Extended PLC connectivity via IEEE 802.3 CSMA/CD 10Mbps and 100Mbps Ethernet  LAN port connectors  

▪ Network switch that has Auto negotiate, Sense, Speed, and crossover* detection  

▪ Direct connection to BaseT (twisted pair) network switch, hub, or repeater without an  external transceiver  

▪ Protocol is stored in flash memory in the Ethernet interface and is easily upgraded  through the CPU serial port  

▪ Communications with remote PLCs and other nodes reachable through routers. The  gateway IP address must be configured  

▪ Internet access via web pages served up to standard web browsers

Station Manager

The built-in Station Manager function provides on-line supervisory access to the Ethernet  interface, through the Station Manager port or over the Ethernet cable. Station Manager  services include:  

▪ An interactive set of commands for interrogating and controlling the station.  

▪ Unrestricted access to observe internal statistics, an exception log, and configuration  parameters.  

▪ Password security for commands that change station parameters or operation.
