Communications configuring
3-304 System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
3.28 Communications with WinCC (MPI)
You can handle and monitor the proces variables of your SIMADYN D
station using WinCC. A WinCC station is connected to SIMADYN D using
an MPI subnet via a CS7/SS52 MPI.
• Configure your hardware in HWConfig, so that your SIMADYN D
station is equipped with a minimum of one CS7- carrier module, which
includes, as a minimum, one communications submodule SS52.
• The communications interconnection using the MPI subnet must be
configured in the SIMATIC manager.
Additional information
on the network configuration, refer to "Hardware Configuring with STEP
7".
You will require the following components so that you can use WinCC for
operator control and monitoring of your SIMADYN D station:
• CFC in order to declare function block I/O as process variables,
• WinCC itself to configure the WinCC station.
Additional information
on operator control and monitoring, refer to the User Documentation
SIMATIC D7-SYS, STEP 7 option packages for D7-SYS , chapter “CFC”.
Use the following function blocks to initialize the MPI link:
• One @CSMPI central coupling block must be configured for each
SS52-MPI.
• One communications block S7OS must be configured for each
SIMADYN D CPU and SS52-MPI module, which is to be addressed
using a WinCC station.
These function blocks are configured as follows in the CFC:
