Principle Of Operation - Siemens SIMATIC RF1070R Manual

1 Introduction
Note Another application example for linking the
SIMATIC RF1040R/RF1070R reader to an S7-1500 station via the RF170C
communication module can be found in the Siemens Industry Online Support
(SIOS) under \4\.

Implemented functions
The following functions are implemented in the application example:
•
Parameter assignment for the point-to-point connection of the communication
module CM1241 RS232.
•
Reset SIMATIC RF1070R reader.
•
Monitor the antenna field of the RF1070R reader and select the card located
there.
•
Receive the UID from the SIMATIC RF1070R reader from the CM1241 RS232
communication module and store it in a data block.
Advantages of this solution
•
Save time and money when commissioning your own automation solution.
•
Reusable STEP 7 code. This can be easily adapted for extensions.
Note This application example can also serve as a basis for controlling a SIMATIC
RF1040R/RF1070R reader centrally on an S7-1500 CPU via the CM PtP RS232
BA; or decentralized via an ET 200SP CM PtP.
