Tagging results Using a barcode

Recommended Posts

Hi All,

Sorry, I am new to this and was wondering if someone could help me. I have a number of results that I want to be able to tag to a specific barcode. The basic idea is that I want to first scan a barcode which will be linked to a device, then I want to test this device and the results gathered from it (Voltage, Current etc.,) could be stored in a data table along with that barcode, so when that barcode is scanned again, those results would be again displayed. Is this possible to do and if so, how would I go about doing it.


The equipment I have is a V570, A metrologic 7120 barcode scanner and the values I want it to store are voltage, current and two calculated values from the PLC.


Thanks for reading!


Best regards,

Totally possible.


Start by looking at Help->Examples .. Project Examples->FB Protocol.  You'll read barcodes as strings via the RS232 port and extract the data you want using the String functions.  Beat on it a bit and post your code for more specific help from the forum.
