    Only some of zenon drivers are supporting an extra 'Connection State' indicator variables. In iec850 driver this indicator informs about the state of association, not only if a connections with the IED is there or not; if has 10(!) states. In IEC62056 driver there is no special indicator.

    All zenon drivers, by connection loss, are setting the status bit INVALID to all variables. To check if a device is online you can evaluate this status bit in a reaction matrix, linked with any variable.
