Reading out UID with SIMATIC RF1070R via serial communication modules
https://support.industry.siemens.com/cs/document/109780625/
In addition to controlling access to buildings, RFID-based identification systems can also be used for the operation of machinery. This allows finely graded access concepts to be implemented or user-specific instructions to be stored. Companies have been using RFID-based identification card systems for many years to control access to buildings.
The growing need for security and increasing requirements for documentation call for solutions that can control access to machines and equipment on a user-specific basis. The SIMATIC RF1040R/RF1070R readers provide the option of using employee identification cards even when operating machines. This allows finely graded access concepts to be implemented or user-specific instructions to be stored - all with one card.
The RF1070R reader can be linked to a SIMATIC S7-1200 CPU using the CM1241 RS232 communication module. With this link, communication happens over the Freeport protocol.
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.
The following graphic shows the configuration scenario that is implemented in this example.
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.
