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.

Did anyone wrote a apk for this that we can use? access WebPanel USB port to read/write data from CtrlX core is important in several applications were we need to switch Controller and HMI to CtrlX platform.

I did write one for a customer for a mifare RFID reader that we tunneled via UDP to the core (so all protocol stuff was in the PLC code), i think they payed around 10k€ for the app (they are using it in 10 wr panels). One of the mifare devices are connected directly to the core and handled via SysCom. But the panels are up to 30m away from the cabinet so the usb cables got to long. 

But if you only want a usb-handscanner and file access the fully kiosk browser's premium edition supports both:

But its still more flexible (and much cheaper) to move the core out of the drive so you get access to a real usb host.
