Modbus - Deployment
You may deploy the CP 240 Modbus either in master or in slave mode. At
both modes the module occupies each 16Byte for in- and output data at
arbitrary area in the CPU.
For the deployment with Modbus a hardware configuration must always be
executed.
The following components are required for the deployment of the System
200V Modbus modules:
•
Each 1 System 200V consisting of CPU 21x and CP 240
•
Siemens SIMATIC Manager
•
Programming cable for MPI coupling (e.g. Green Cable from VIPA)
•
GSD-file VIPA_21x.gsd (V1.67 or higher)
•
VIPA handling blocks Fx000002_V120.zip or higher
•
Serial connection between both CP 240
The CP 240 always requires a hardware configuration. For this the inclusion
of the VIPA_21x.gsd into the hardware catalog is necessary. The
parameterization has the following approach:
•
Start the Siemens SIMATIC Manager
•
Install the GSD-file VIPA_21x.gsd in the hardware catalog.
•
Create a virtual Profibus system in the hardware configurator with the
CPU 315-2DP (
6ES7 315-2AF03 V1.2)
.
•
Add to this system the slave system "VIPA_CPU21x" and assign the
Profibus address 1.
•
Configure your System 200V starting with the CPU 21x. Use a CP
labeled with "Modbus".
•
Parameterize the CP 240 after your needs. The CP 240 occupies each
16Byte in the CPU for in- and output.
•
Transfer your project to the PLC.
Except of the "Modbus Slave Short", the communication always requires a
PLC application. For this the communication happens via handling blocks
that you may include into the Siemens SIMATIC Manager by means of the
VIPA library
Fx000002_V120.zip or higher. The library is available on the
VIPA-CD "ToolDemo" or at ftp.vipa.de.
Note!
More detailed information about the installation of the GSD-file and the
library is to be found in the chapter "Project engineering".
