PLCSCO

Barcode PLCSCO (Set COnveyor) allows setting conveyor ID and conveyor destination to desired values. The format is as follows:

PLCSCO<conveyorID>.<destination>

Example:

PLCSCO4.10

If <destination> is missing, it is set to an undefined value.

The settings will be forced upon the next released product (only the next one) regardless what the scanner settings (i.e. ConveyorID and Destination) are.

To cancel this forced constraint, scan barcode PLCSCO-

Scanning PLCSCO just displays current conveyor configuration.

PLCCLSE

Barcode PLCCLSE means Clear Last Sequence Errors - i.e. clear all rescanned NOK product IDs.

Use it to get rid of any automatically rescanned product IDs.
