6.4 Example
6.4.1 Overview and conditions
This chapter is intended to introduce the first-time user of the CP143 H1 / TCP/IP to the H1 LAN
and TCP/IP for the PLC. The emphasis will be on the use of the configuration software for the
CP143 H1 / TCP/IP.
The chapter describes simple communication system that allows control of the communication
processes.
You need to have some knowledge of the CP handler modules. These CP handlers are standard
function modules. Programs on the PLCs provide the required access to communication functions.
You should have the following equipment to execute the examples:
• 2PLCs
• 2 communication processors CP143plus (BG81A) or CP143 TCP/IP (BG89A).
• Communication link consisting of
- 1 LAN cable with 2 coaxial T-pieces.
- 2 Terminators
• Software package
- Configuration software SSN-SW893
- MC5 Programming package for programming of PLCs
- Standard handler modules for the respective PLCs.
The basis for this problem is described in chapter 6.4.2. To implement the example it is necessary to
program the PLCs in the STEP

5 language from Siemens and to configure the communication
processors CP143plus and CP143 TCP/IP. Chapter 6.4.3 contains the respective programs for the
AG135U or AG155U PLCs.
The results obtained from the communication processes are described in chapter 6.4.6.
