    Hi,

    In my Project, I am running Codesys in raspberry pi Compute Module 3+.
    Configured Codesys as OPC UA server and configured with more than 120 variable.
    Facing an issue, while displaying all these 120 variables in a single screen[OPC UA Client is HMI ].

    running Codesyscontrol 4.4.0.0 armhf codesyscontrol based on SDK 3.5.17.30'

    Tried changing this below setting but, no luck.

    [CmpOPCUA]
    MaxNodesPerRead=200

    Any input on resolving the issue highly appreciated.

    Best Regards,
    Mani
