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). April 23, 2018 at 6:41 am #3586 MikhailModerator 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 Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
