PROFINET communication

PROFINET IO controller

Connection of field devices to Industrial Ethernet with PROFINET

User interfaces

OPC interface

The supplied OPC server can be used as a standard programming interface for PROFINET IO controller to link automation applications to OPC-capable Windows applications (Office, HMI systems, etc.).

Programming interface via C Library;

For applications that want to use the PROFINET IO controller functionality directly over C/C++, the IO-Base interface can be used. This interface is of a similar design to the DP Base interface of PROFIBUS modules CP 5613 A2 and CP 5614 A2. It is therefore possible to port existing PROFIBUS DP master applications to PN IO-Controller applications.

The released compilers can be found in the readme file of the SIMATIC NET CD products at http://www.siemens.com/automation/csi/net.

SOFTNET PN IO and CP 1616 use compatible functions of the IO-Base interface.

Mode of operation

With SOFTNET, the complete protocol stack is processed in the PC. This architecture means that the performance depends on the configuration of the PC used or the loading on the PC.

Configuration

Configuration is performed with STEP 7/NCM PC
