At a Glance

Brand	Siemens
Model	6GK7243-1EX00-0XE0
Product Type	CP 243-1 Ethernet module
Core Function	Connect an S7-200 controller to Industrial Ethernet
Compatible Series / Application	S7-200 automation systems

Controller networking

Exchange data with S7-200, S7-300 and S7-400 controllers.

Engineering access

Configure, program and diagnose the S7-200 over Ethernet.

Connection planning

Use one CP per CPU with up to eight S7 connections.

Product Overview

6GK7243-1EX00-0XE0 adds Industrial Ethernet communication to the SIMATIC S7-200 system through the CP 243-1 Ethernet module.

An S7-200 can communicate with other S7 controllers or an OPC server, and STEP 7 Micro/WIN can reach the controller remotely for engineering and diagnostics.

Ordering focus: Plan one CP 243-1 per S7-200 CPU and allocate the S7 data-exchange connections separately from the Micro/WIN connection.

Key Functions

Controller data exchange

Up to eight S7 connections support XPUT/XGET and READ/WRITE communication.

Remote engineering

A separate STEP 7 Micro/WIN connection provides Ethernet configuration, programming and diagnostics.

Industrial Ethernet interface

An 8-pin RJ45 socket supports 10 Mbit/s and 100 Mbit/s transmission.
