Teys Brothers Meatworks Inventory Control
Development of a system which integrated the clients main computer, PLC's and
bar code readers. Bar-Code labels on cartons of packaged meat were scanned after exiting the boning room.
The bar-code contained the product code (1 of 999 products) and the time and date of packaging.
The cartons were then sorted to any one of five destinations (palletisers)
along conveyor systems and then to either cold storage or a freezing tunnel. These destinations were derived
from files in the the PLC data table, which were updated by the clients computer according to customers
orders.
The full bar-code, as well as the final destination was recorded and this
information was passed to the clients computer and stored in a database for accounting and inventory
purposes.

Allen Bradley Adaptascan barcode scanners communicate via Allen Bradley
DeviceNet to an SLC500 PLC system which provided a hard wired interface to the existing conveyor control
System for sorting purposes.
Allen Bradley WinLinx provided DDE
interface to an Microsoft Excel Spreadsheet, enabling operator configuration and inventory control.
A Datalogic DeviceNet to RS232 interface provided communications to an Anritsu Metal Detector to control
rejection.
