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 tag of a toolholder 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 tag has to be detected each time (single-tag). The tags
in this scenario are transponders of type SIMATIC RF640T.
The SIMATIC RF620R reader reads the information from the tags with its integrated antenna
and transfers it to the SIMATIC S7 controller via a communication module. Depending on the
stored tag information, the SIMATIC-S7 performs different control tasks, for example,
automatically providing a suitable tool for an industrial robot at the correct time.
