Manual VIPA CPU 21x Chapter 4 Deployment of the CPU 21x-2BT10 with TCP/IP
HB103E - Rev. 05/45 4-45
Example communication CPU21x-2BT10
This chapter provides an introduction to use the TCP/IP bus system for the
System 200V. The object of this chapter is to create a small
communication system between two VIPA CPUs 21xNET that provides a
simple approach to the control of the communication processes.
Knowledge of the VIPA CP handling blocks AG_SEND and AG_RECV is
required. CP handling blocks provide the options required to utilize the
communication functions in the programs of the PLCs.
The minimum technical equipment required for the example is as follows:
Hardware
- 2 CPUs 21x-2BT10 from VIPA
- 1 PC or PG with Twisted Pair Ethernet connection
Communication line
- 3 bus cables
- 1 Swich/Hub
Addresses
- 2 IP Addresses and subnet masks for 2 CPs
Software package
- SIMATIC Manager from Siemens V. 5.1 or higher
- SIMATIC NET
The implementation of the example requires that the two CPUs be
programmed as well as the configuration of the CPs by means of NetPro
from Siemens.
Note!
The complete example is to e found as zip at ftp.vipa.de/support/demofiles.
You may transfer the PLC program directly to both CPUs.
