Could not connect to controller

    Dear readers,

    I'm new to codesys V3 and structuredtext programming. My background is embedded realtime systems using C(++),
    I'm running a TM251MESE controller from Schneider and use the SoMachine 4 development environment (codesys 3).

    I'm having difficulties connecting to the controller. The controller is available in the controller selection but when connecting (login) I get a error (see attachment).

    Could someone help me out here?

    Best regards

    PS: The controller is in "RUN" state (physical switch on the controller).

    Hi All,

    Thanks to Schneider Electric we found that the gateway server was not configured properly.
    In the "gateway management console" application we needed to (re-)configure the interfaces.
    Was needed after a change in the network IP range.

    Now we're able to connect.

    Bets regards

    I am also having the same issue i.e. Not able to login to the controller but I am not able to edit gateway Management Console - Gateway Configuration. Some of the screenshots from my program.
