HMI CONNECT TO NON PLC WITH RS232

6 posts in this topic

HELLO, i want to ask.

Can HMI connect to Non PLC device(example: zebra printer,Barcode Scanner or Weighing scale) using rs232 ?

if can, can you suggest me what type of HMI that can connect to Non PLC device Using rs232 communication?

thank you, have a nice day....

It depends on the protocol used by the device and supported by the HMI. The most common protocol used by non-PLC devices is Modbus.

I agree with Archie. 
If you want to send ASCII text messages out over your serial port to a weight scale, then you will need to customize your HMI. Barcode is normally ASCII inputs that most HMI's will support. Zebra printers have their own protocol over serial or Ethernet connection. 
Look at the AdvancedHMI for the ability to do this withing the Visual Studio environment.

Their website will also sell industrial PC's loaded with AdvancedHMI.

I'm not aware of any HMI that will communicate with a Zebra printer. The last project I did with a Zebra printer, I used AdvancedHMI with a panel PC. That let me install the printer using the driver from Zebra. It did require some code writing, so it took a little time to do.

Hello

it is Something possible. We use to do it because barcode reader is almost same as keyboard. For label printer, if your panel is able to handle 'escape P' mode, it should work.

that's something very traditionnal for industrial panel.

best regards
