PC Components in the Catalog
For the SIMATIC PC station, you can select the following components:
S Application
- 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:
- Connection-oriented services
- DP services (for example, DP-V0 and DP-V1)
- 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 S7-400.
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
S CP Industrial Ethernet
