Purpose of this manual
This manual is designed to support you in using the CP 243-1 communications
processor. You are provided with information on how to employ this communica-
tions processor to communicate via Industrial Ethernet (IE).
Prerequisites
A prerequisite for understanding how the CP 243-1 works is familiarity with this
manual and the "SIMATIC S7-200 Automation System" (MLFB: 6ES7298-8FA21-
8AH0) manual. You must also have a basic understanding of the TCP/IP protocol.
Target group
This manual is directed toward engineers, programmers, commissioning engineers
and maintenance technicians with a general knowledge of automation and com-
munication systems and human machine interface systems.
Sample program
This manual contains a sample program that provides you with information and as-
sistance in programming the CP 243-1. This sample program was created with
STEP 7-Micro/WIN 32 (MLFB: 6ES7 810-2BC02-OYXO) and can be run on an S7-
200 CPU, type 224. To run this sample program on another S7-200 CPU, you may
have to adjust the configuration of the program.
