    Hi

    I'm trying to create a PLC on my Raspberry Pi for testing a Profinet device I'm working on. I have a few warnings which seem to be stopping me from controlling my device. Can anyone shed any light on the warning? I have tried controlling my device with ladder logic but presuming it's these errors preventing me getting things up and running. (i've redacted a couple of words in the image as they happened to have client details on)

    Hi,
    did you scan this pn device by rightclick in the device tree and add it that way?
    Best Regards

    Hi Edwin,

    Thanks for your reply. Yes, that's the way i added the device. If i click on the screen now i see this information... as you can see there is a warning here but when i added everything it all seemed to appear in the device tree as expected

    There is also this screen showing 'the bus is not running' - see screenshot

    ...then the modules (identified via MdouelIdentNr and/or SubmoduleIdentNr) are not defined in the GSDMl...!

    Thanks Edwin,

    I have used PROFINET master simulator to control this pump with it's GSDML file successfully though? Perhaps there is some other reason for the error?
