possible to reach USB device and printer via WR2110 Panel

[orkun]

Hello Dear ,

It is necessary to send a command to the printer via PLC and read data from the USB containing the *.csv file.

Is this possible according to the following topology?

So, can we do this using the USB ports on the HMI(WR2110)?

 

 

please take a look topology file...

Thanks in advance

Why not plug them into the core instead (Using a usb hub)?

Then you can use NodeRED to read and write data to serial  printer using node-red-node-serialport.

There are examples to read csv files in NodeRED here: https://cookbook.nodered.org/basic/parse-csv

Thanks for reply,

as I see and understand no USB port on the drive(with core)?

and illustration is wrong(updated again , take a look) , ı have no plc core , I have drive with core.pls consider this.

In therory it is possible, but afaik it involves writing your own Android App to handle it, and I'm not sure its allowed to install custom apps into the WR panels.

And even if it was, the development effort will be much more costly then rethinking the layout and get an external core X3. Because then you have the USB interface and can get it working in a few hours using NodeRED.

Hi,

you can write your own application, compile it into an apk file and install it on the webpanels. At this point, the WebPanel works like a tablet/smartphone.
