Bar Code Readers

PureLogic Controls Limited has experience in using industry leading barcode readers and writing decoding logic so that your product goes to the right loading bay.

Barcode readers can be used as data entry to the PLC. Loads can be fixed with a unique barcode prior to entering the system. This barcode would be scanned with either a fixed reader or hand scanner. The barcode can then be associated with a particular route through the system or required dispatch lane.

As the product arrives at a divert or other decision point on the system a fixed barcode reader would scan the label and compare this with a list held in the PLC or WMS to determine the required direction for the product.

A typical barcode reader network would be connected to one or more multiplexers. Each multiplexer would communicate with the PLC over a serial port or via ethernet.
