    Problem with C-PS-easyPanel-EG-NG

    Problem with C-PS-easyPanel-EG-NG

    Hello,

    i have a problem with the easy panel.

    I have 3 easy panels in my machine. I added them all to a mode forwarder. The first 2 easy panels are working fine but the 3rd is not responding.

    When i check the software i see that the 3rd one has a "Dereference of invalid pointer" for the "REFERENCE TO OpconModeHandlerExtension"

    Maybe anyone has some suggestions what i can do with this problem.

    Thank you.

    There is a library parameter in the OpconBase library that limits the number of EasyPanels to 2 per handler. But you can change this in the library manager:

    Please don't forget to activate the TwinCAT configuration after changing the value.

    You must increase the OpconBase constant OPCON_EXTENSION_ADAPTERS_PER_EXT for maximum number of extension adapters in the library manager:

    Some hints:

    1. After changing library parameters, I recommend clean project and activate configuration.
    2. Never delete libraries in TwinCAT, otherwise you will lose such library parameters.
      Only delete unused libraries that are not managed by Control plus Studio / OES
      (check this button: SteffenR_1-1670849742887.png).
    3. With TwinCAT 4020.28 make sure that you are using all Bosch patches, otherwise library parameters can get lost.
      If you do not have access to the Bosch-internal release server, contact our Helpdesk by email.
