GT1265 HMI to FX3U barcode

[Mikul 0]

Anyone have any experience in setting up a barcode reader to a Gt1265 HMI with a FX3U processor? I am looking for information on associated PLC program and any possible setup tricks. Many thanks

You should have two serial ports on the HMI, one is RS422 and the other is RS232. The RS422 port is for connecting to the FX3U. You can take the bar code scanner into the RS232 port. When you develop the HMI project in GT Designer, you have to set up two connections, one for the PLC and one for the bar code scanner. In the detail settings for the barcode scanner connection, you define a data register where you want the data from the scanner to end up, and the number of data registers you want to assign to the data. Each data register can handle two ASCII characters, so if the scanner is sending 20 characters, you want to assign 10 data registers. Set up the bar code scanner to send the information you want. When you scan a barcode, the ASCII characters will show up on the PLC in the data registers you assigned, in ASCII hex format. Now you can do whatever you want to do with the information. The FX3U has a pretty good selection of ASCII (aka String) commands for parsing the information. GT Designer comes with a set of PDF manuals that show you how to set up on that end, and the software manuals for the FX3U has all the string instructions in it. If you have any more specific questions, come back here.

Sounds fairly easy. I have read all the docu earlier and am very familiar with the FX3U so if I have any more questions I'll post. Many thanks
