DaveE Posted April 10, 2014 Report Share Posted April 10, 2014 Good evening I have written a program for a barcode scanner that reads a barcode and parses the info to the screen, and then communicates it to a printer I do however have a couple of issues 1) If I plug the scanner into the port of the V120 it doesnt work, however I think that must just be me, as I downloaded a program called termite and plugged in the PLC to one port and the scanner to another, set my ports to forward in the program from the scanner to the PLC and it works. The major problems that I am facing is that unless I switch screens the HMI does not update, cant work out how to do that.. any thoughts The next problem is that if the first barcode I scan is 20 characters long and the next is 15 then the last 5 characters do not clear out, but stay with the new scan, this I dont understand so if anyone has some ideas I would love to hear them Thanks Quote Link to comment Share on other sites More sharing options...
