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. In terms of design, this interface is based on the DP base interface of the PROFIBUS modules CP 5613 A2 and CP 5614 A2. Therefore, the porting of existing PROFIBUS DP master applications to PN IO Controller applications is also possible and easy.
The released compilers can be found in the readme file of the SIMATIC NET CD products athttp://www.siemens.com/automation/csi/net.
SOFTNET PN IO and CP 1616 use compatible functions of the IO-Base interface.
Mode of operation
For SOFTNET, the entire protocol stack is handled in the PC. This architecture means that the performance depends on the configuration of the PC used or the loading on the PC.
Configuration
The configuration is done in STEP 7/NCM PC as of V5.3 SP1
