Utilization of RFID systems in the PCS 7 environment
Part number:

Application
Today's world, such as in the pharmaceutical industry, is determined by standards, guidelines and legislation. At the fundamental level of these regulations are definitions of the requirements for the product manufacturing process and quality assurance.
The combination of automation technology and RFID technology offers a reliable and efficient solution for fulfilling these requirements. Thanks to the use of mobile data storage devices (MDS) in the manufacturing process, information regarding identification can be written and read contact-free and reliably using the RFID system.

In this example, the focus is directed towards monitoring mobile containers that are integrated into a process control system by means of an RFID system. The RFID components used for this can be integrated into SIMATIC PCS 7 and STEP 7 and are specifically designed for applications in an industrial environment.

Solution
The Siemens SIMATIC RF is an innovative series of systems with a multitude of benefits. Contact-free data transmission is ideally suited for industrial applications and guarantees reliable and cost-effective identification. Standardized system integration enables quick and easy deployment in any application.

The figure shows a possible configuration for the integration of an RFID-System in a PCS 7 environment.

As part of this application example, the configuration of the SIMATIC RF300 RFID system is described both for an S7-400 controller and an S7-300 controller.
Integration in PCS 7 is done using an "RFID_IF" interface block, which is separately available below for download as source code and in compiled format, integrated into a Demo Project. It forms the interface between the RFID program and the PCS 7 process.

The PCS 7 solution is based on the STEP 7 project for the MOBY_FB (FB45). This project is included in the demo project for the RFID_IF block. However, you can also obtain this STEP 7 project from the following entry 61199127.

Validity
The FB45 is a block for the ASM 475, ASM 456, RF170C and RF180C communications modules. This application can thus be used with these RFID devices.
The project has been created with the following software:

  • SIMATIC PCS 7 V8.0 SP1 Upd1
  • STEP 7 V5.5 SP3 Upd4 with CFC V8.0 SP4 Upd1 (integrated into PCS 7)
