    Hello,

     I encountered some issues after create a center HMI.

    1. I have 3 active HMIs and two projects for two stations

    2. A license error is showed in the center HMI, I do not know how to solve it(see attachment)

    3. How to get the interlocking function between three HMIs

    thank you

    Every communication with the License Server needs the client certificate to be trusted on the server side, i.e. on the PLC system. If you have a central HMI, the certificate of the HMI panel needs to be trusted on both PLCs.

    This also applies for the communication between Control plus Studio and the License servers. The error message (LicenseServer.png) is wrong in most cases. The message also appears when the certificate is not trusted, not only when the dongle is actually missing. This bug has been fixed in CpStudio 5.8.2.

    For the interlock function of the HMI, every HMI instance needs a different ID. You can set the ID in the HMI settings:
