Hello, I want to connect a USB "OPTICAL HAND CODE READER MV320 6GF3320-0HT01" to the IOT2040 and send the 2D read code to a S7 controller. 6GF3320-0HT01 OPTICAL HAND CODE READER MV320 The code reader act as a USB keyboard would do. So if I scan a barcode with the value "123", it send "123" as a USB keyboard would do. I can connect the MV320 to a computer, open Excel, scan "123" and "123" will be in the selected cell. There is currently only wired RS232 solution for Ident device. The "SIMATIC Ident Configuration Guide" shows there is a planned solution for a M3-modem that would connect to S7 controller, but I opened a support request and it will not be release. SIMATIC Ident Configuration Guide So this is a workaround. I looked into the current nodes and flows into the Node-RED website, but I can't find any node related to USB keyboard. I want to test everything with a USB keyboard, then switch to the MV320. Do you have any advice? Best regards, Hugo Dufour

Hello, I found and tried loads of nodes example, but unable to install them correctly. node-red-contrib-autokey 0.0.3 This one seems to be the one I want for my application, but I get error when I try to install it on PuTTY. IOT is connect to internet. Do you experience the same issue? Best regards, Hugo |

First thing coming to mind is the version of node-red. Maybe version 0.0.3 of your package is incompatible with the node-red-version. Just like the latest OPC-package is not usable and we use version 0.2.11 instead. Second thing: Here it says something about dependencies. Have you checked this? |

Hello, With the help of turner42, I am now able to use a USB keyboard on the USB host port of the IOT and see the result in Node-RED. https://support.industry.siemens.com/tf/us/en/posts/usb-node-red/179852?page=1&pageSize=10 ------------------------------------------------------ Michael, WOWIt works! Thank you soooo much! Here is what I did:

Hello Pac8, If you use the reader with your PC, do you get the same result in a cell of Excel? Best regards, HugoD |
