Barcode reader to plc table

[deekay999]

I have an application whereby a barcode reader must sense a label and put the data in a table in a PLC. Using a decoder? (i think). This info is passed as ASCII? to the PLC

How would I handle the data for use in a MES?

Thanks
Dave

Hi,
barcode reader reads valid barcode and sends ASCII string to configured communication channel of the PLC.
In PLC program should be operations to read buffer and extract part of the string you need. Later you may compare string from barcode reader and file and have some actions.
Thanks.
