PLCSCO

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

PLCSCO<conveyorID>.<destination>

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

Example:

PLCSCO4.10

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.
