Via the ASM456 communication module, SIMATIC RF200 Readers are integrated into a control system via PROFIBUS. The S7 blocks “Ident blocks” or “Ident profile” are used to control this configuration.

A SIMATIC RF200 Reader shall be integrated into a S7 control system via PROFIBUS. Via the reader, fundamental RFID functions shall be realized. 

The ASM456 communication module has been developed to connect the SIMATIC RFID Reader to a S7 control system via PROFIBUS. The S7 program blocks “Ident blocks” are used to control the readers.
The basic example to this solution was kept simple. The focus lies on the fundamental steps to configure and program the automation solution. The following illustration shows the structure of the solution:
