System overview
3.3 System configuration
In this scenario, it is an advantage that the tag can be directly secured to metal on the metal
pallets. The small-dimensioned SIMATIC RF310R reader is integrated in the conveyor
elements in such a manner that it can communicate with the tags from below. Thus, it is not
necessary to align the pallets or to attach several tags.
The data of the entire production order (5000 bytes) is stored on the tag. This data is read at
each workstation and changed or supplemented depending on the workstation, and then
written back again. Thus, the status of the engine block assembly can be determined at any
point in time, even if there is a failure at the HOST level.
Thanks to the extremely high data rate, a very short cycle time for the work steps can be
factored in, which results in high end product unit numbers (engines).
The entire production order that is saved on the tag can also be manually read via the WIN-
LC terminal located at each workstation. This means that virtually no additional data
management is required on the control PC.
The production order data can also be read for servicing purposes via the mobile SIMATIC
RF310M handheld terminal.
