13 SIMATIC NCM PC Project Engineering Tool
PC Components in the Catalog
For the SIMATIC PC station, you can select the following components:
SApplication
-Application (standard application)
You use standard interfaces to communicate with other applications and devices via your PC module.
The user programs included in the application use suitable interfaces for communication, such as the SAPI programming interface or the SEND/RECEIVE programming interface.
You can configure the following communications services depending on the module inserted:
-
-DP services (for example,
-PROFINET IO
Note how these differ from the user programs that use the communication service as OPC clients via an OPC Server as described below.
-OPC Server
You use the convenient interface to an OPC server to communicate with a programmable controller such as a SIMATIC
The OPC Server can be configured as an interface to all available communication protocols. You can create this object only once in a PC station.
You can then use this OPC Server for communication with any number of user programs (OPC clients).
The following communications services can be used depending on the modules inserted:
-All types of connection
-DP services
-PROFINET IO
