Chapter 5 CP 240 - EnOcean Manual VIPA System 200V
5-4 HB97E - CP - Rev. 11/30
Fast introduction
The communication processor CP 240 EnOcean enables the process
coupling to different destination or source systems based upon the wireless
EnOcean communication.
The CP 240 EnOcean is supplied with voltage via the back plane bus. For
the internal communication the VIPA FCs are used. For the project
engineering of the CP 240 EnOcean together with a CPU 21x in the
Siemens SIMATIC Manager, the inclusion of the GSD VIPA_21x.gsd is
required. To enable the CP 240 EnOcean to communicate with the CPU, a
hardware configuration for the system is always necessary.
A general description for the project engineering of the CP 240 is to be
found in the chapter "Project engineering".
By placing the CP 240 EnOcean in the hardware configuration into the
"virtual" Profibus system, the required parameters are automatically
created. The parameter area has the following structure:
Byte Function Value range Default parameter
0 reserved
1 Protocol E0h: EnOcean -
2...15 reserved
You have only to set E0h in Byte 1 as protocol for EnOcean. The other
parameters are reserved and not evaluated.
With the help of VIPA-FCs you control the communication between CPU
and CP 240. For this, send and receive data have each a reserved
2048Byte buffer which may handle up to 150 telegrams. Together with a
CPU 21x the following handling blocks are used:
Label FCs Description
SEND FC0 send block
RECEIVE FC1 receive block
SYNCHRON_RESET FC9 reset and synchronization of the CP 240
Always use telegrams with a length of 11Byte for the communication. At
the transmission, the CP 240 EnOcean extends the 11Byte automatically
with 2 synchronization bytes and a Checksum to 14Byte res. cuts the
14Byte telegram to 11Byte at reception.
The recent GSD-files and libraries are to be found either on the CD-ROM
"SW-ToolDemo" or under ftp.vipa.de. The installation of the CP 240
EnOcean happens with this approach:
1. Install the GSD-file VIPA_21X.gsd in your project-engineering tool.
2. Install the VIPA library Fx000002_Vxxx.zip with the handling blocks in
your project-engineering tool.
3. Configure your System 200V, parameterize the CP 240 EnOcean and
program the communication.
4. Transfer your project into the CPU.
