Scenario for material handling control

This scenario shows a possible solution for monitoring and controlling the infeed of material
to a production line. The objective is to provide the right material at the right time. This can
be particularly useful in plants with frequently changing manufacturing scenarios for ensuring
that incorrect infeed and downtimes are minimized.
Features of the scenario
The conveyor moves different transport containers past the readers in an arbitrary alignment.
The RFID tag is, however, always applied to the transport containers with the same
alignment. The tags in this scenario are transponders of type SIMATIC RF620T.
The conveyor has a maximum width of 80 cm in this example. The transport velocity is up to
2 m/s. With this arrangement only a single RFID tag has to be detected each time (single-
tag).
In this scenario a SIMATIC RF630R is used as the reader. Optimum reading reliability is
ensured by two external antennas in a portal arrangement. The SIMATIC RF630R reader
reads the information from the tags on the transport containers and transfers it via a
communication module to the SIMATIC S7 controller which controls the process in
accordance with the tag information.
