    Hello,

    Is there any way to read communication status from modbus TCP device as
    input channel in rapid scada?

    I see communication status in communicator, is it possible to show that status as input channel?

    Also i need that as a trigger to send email as notification that we lost communication with that device (as watchdog).

    Hi,
    Yes. Add new input channel of the Calculated type and use the formula:
    Stat(1) > 0 ? 1 : 0
    where 1 is the input channel number of any tag.

    To send notifications you need Automatic Control Module, see http://doc.rapidscada.net/content/en/modules/mod-auto-control.html
