3 Configuration of SIMATIC S7
3.1 Overview
SIMATIC S7 is the key family of PLC products of the Siemens A&D division. In
MM8000 you can integrate the S7 PLC units via an OPC server.
The configuration is very similar to the one described above for a generic OPC
subsystem. As discussed more fully in section 2.1 above, the configuration in-
cludes three logical steps:
1. Add the OPC Driver (NS8019), and define links to OPC server and items
2. Add the S7 subsystem and the related points
3. Link points to OPC items and set the item class that defines data conversions.
3.2 SIMATIC S7 configuration
3.2.1 Configuration checklist
Verify that you have satisfied the items needed in the first checklist before proceed-
ing to the configuration procedure that follows.
ITEMS NEEDED FOR CONFIGURATION
OPC server
The PC name or IP address of the machine where the OPC server named
OPC.SimaticNET runs.
OPC items
OPC items list -- or-- CSV file (strongly recommended) including such a list.
The MM8000 OPC item class, defining the conversion rules to MM8000 points.
Control unit objects
The objects to define in Composer as data points and then link to the OPC items.
Plug-ins needed:
Plug-ins #357701 (OPC driver) and #357601 (S7), which must be installed before
you can configure your system.
3.2.2 Configuration procedure
The following are the configuration procedures for an S7 unit.
Adding the OPC driver
1. Open the Composer project.
2. If not already done, add the OPC driver. You need to select the Station node in
the path:
