    Default Interlockings

    Hello,

    I have a problem with the interlockings module. It looks like in case that one of the variables is INVALID, The interlock will not work.
    Also what is strange is that the INVALID statusbit is not shown in the uncollapsed list of the statusbit, but you can type it.
    Unfortunately the interlock wil not work.

    What I want is that if a specific RV is IVALID A dialog button must be interlocked. I have added this additional button in the command_processing dialog.

    I use V7.60 SP0

    Please help

    Default Re: Interlockings

    While RV is INVALID the command processing does not allow "normal" commands (action buttons are grayed out or not visible at all). While INVALID only 'forced command' (emergency Open) and 'replace' (alternative value / substitution in HMI) actions are allowed.

    To disable additional, your own, dialogs you can link RV (or ConnectionState) variable with a reaction matrix evaluating INVALID/connection loss and then calling a function 'write set value' to some additional, internal, BOOL, network, variable.
