Today’s world of pharmaceutical industry is determined by standards, guidelines and laws. On the basis of these regulations the requirements for the manufacturing process of products and the quality assurance are defined.
The combination of automation technology and RFID technology offers a reliable and efficient solution for fulfilling the given tasks. By means of mobile data memories (MDS) in the production process information for the identification can be written and read contact-free and reliably by means of the RFID system.
The main focus of this application is directed at monitoring mobile containers which are included within a process control system by means of an RFID system. For this, RFID components that can be integrated in SIMATIC PCS 7 and STEP 7 and that are especially designed for the use in industrial environments are being used.
The solution of the mentioned task is the SIMATIC RFID system family (RF200, RF300, RF600), which has been designed especially for the production environment and can be integrated into the SIMATIC automation level.
In the course of this application, the RFID system SIMATIC RF300 is connected to a SIMATIC S7-300/400 controller. This shall illustrate that any process can harmonize with the RFID system.
A program library is used which forms the interface between the RFID systems and the application.
Generating and operating this RFID library is the main focus of this application.
It is only shown what an application in form of a container monitoring may look like. The following figure shows the components of the application example.
This application description is valid for STEP 7 V5.4 SP5, STEP 7 V5.5, PCS 7 V6.1 SP4, PCS 7 V7.1 SP2.
The block library "29351305_RFID_BIB_CFCV712_S7-400.zip" can be used for all PCS 7 V7.1 projects.
