Simple Communication between SIMATIC RF160C and SIMATIC S7 Controllers
A SIMATIC RF160C should in a simple usage manner communicate with an S7-300/400/1200/1500 via PROFIBUS DP. The RFID systems are connected to a controller via the RF160C communication module and the associated library blocks. The objective of this application is to reliably identify objects with an attached data storage unit (transponder) and to make the stored object data available to further process steps.
This content provides you suitable communication libraries for the whole SIMATIC S7 family. The application example shows the connection of an RFID reader of the RF200/300/600 or MOBY U/D series to an S7-1200 controller using the SIMATIC RF160C communication module via PROFIBUS. Via the reader, data from and to the transponder is made available directly in the S7-1200.
In each library, the following functions are implemented as separate function blocks:
- Reset the RF160C communication module
- Read RFID data from transponders
- Write RFID data to transponder
- Initialize transponder
- Turn antenna on/off
- Check status of RF160C
The library blocks were created in SCL and can therefore be
customized for function extensions or porting to other PLC
