SOFTNET PN IO Siemens

Область применения

Using SOFTNET PN IO, PCs can be linked with PROFINET field devices including PC-based PN IO devices (e.g. with CP 1616 or CP 1604) via Industrial Ethernet.

SOFTNET PN IO is available for the following interfaces:

• CP 1612 A2
• Integral Industrial Ethernet interfaces of SIMATIC programming devices/PCs

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

Особенности

• Cost-effective interfacing of field devices to Industrial Ethernet with PROFINET
• Simple porting of the application with OPC as a standard interface
• High-performance IO data access through RT Base interface for linking into C/C++ applications
• Simple changeover from PROFIBUS modules CP 5613 A2/CP 5614 A2 with DP-Base interface to PROFINET through IO-Base interface
• Uniform procedure and configuration functions for NCM PC and STEP 7
