ModbusGenericSerialMaster: no driver found

    Updated ModbusTCP slave from to

    Slave was happily communicating and had 'green circle' icon with
    Slave is STILL happily communicating with but has the dreaded 'red triangle' icon.

    Poking around online with the target, all I can see in the slave is this...

    Don't care about anything serial here and the device is a ModbusTCP slave. I can see no means to get rid of it (besides reverting to what I saved previously).
    So what is this, and how do I get rid of it to get the very useful 'green circle' icon back, while still using the latest slave version?

    Sorry I don't have a good answer for you.

    Have you checked to make sure you have the newest libraries and have you updated the modbus master device in the device tree to be the newest version? Newest in this case is newest available to your version.

      On my more recent projects I built the device tree out from scratch on v3.5.16.10. No issues on these. This inquiry is from older projects - likely started / based upon 3.5.9. In which I merely updated the modbustcp slave. I have colleagues using these older projects and they were asking about this. So it triggered my memory about this post.

    Any detailed information what error you see in the Slave ( type the name of the Slave to the watch window)
