Scenario For Workpiece Identification - Siemens Simatic RF600 System Manual

4.2.2

Scenario for workpiece identification

A typical characteristic of modern manufacturing scenarios is their multitude of variations.
The individual data and production steps are stored in the transponder of a tool holder or
product. These data are read by the machining stations during a production process and, if
necessary, tagged with status information. This can be used to dynamically identify which
production step is the next in the series. This has the advantage that the production line can
work automatically without the need to access higher system components. The use of RFID
therefore increases the availability of the plant.
Features of the scenario
RFID tags are attached to workpiece holders. Their spatial orientation is always identical.
With this arrangement, only a single transponder needs to be detected each time (single-
tag). The transponders in this scenario are transponders of the type SIMATIC RF640T.
The SIMATIC RF685R reader reads the information from the transponders with its integrated
antenna and transfers it to the SIMATIC S7 controller. Depending on the stored transponder
information, the SIMATIC S7 controller different control tasks, for example, automatically
providing a suitable tool for an industrial robot at the correct time.
