    Default Enabling a USB keyboard for displays running v3.3.0 or lower

    Below is the procedure to enable a USB keyboard on displays using codesys 3.5
    I added what is needed for production

    1) Unzip attached files
    2) Determine if using a touch or non-touch screen
    3) From the proper directory of the zip file (touch or non-touch) use an ftp client to copy the file capp_start.sh to the following directory on the pdm : \home\etc\
    a. Pdm login: root
    b. Pdm password: pdm360ng
    4) Open a telnet client such as PuTTy and connect to the display (make sure you set connection as telnet)
    a. Pdm login: root
    b. Pdm password: pdm360ng
    5) When connected, type the following command in the telnet client: touch \home\etc\ifm\CAPP
    6) Reboot with the keyboard attached and your codesys application will now be able to utilize the USB keyboard.

    If the process gets messed up you can always reset the display by reinstalling the firmware.

    This process only needs to be done on the engineering display. For production, BUP files will be made to a USB drive that will install the firmware and the application. The application will copy all the files you just installed and created into the bup on the USB drive. When in production all you need to do is install the firmware and application from the USB stick using the back-up/restore utility in the PDM config program.

    Unfortunately there is still a codesys bug that is not yet resolved. Once you have placed an element in focus with the tab key and change the input value, pressing enter changes the value however the element focus is not released and the keyboard and PDM keys will stop working. On a touch screen touching another element on the screen will fix this but on a non-touch this will lock up the screen. This appears to be an issue with the codesys run time itself so we must wait for some feedback from 3S
