Data outage alarms

Data outage alarms are generated if data loggers are communicating with VCOM but no data is being imported. As with other alarms, you can choose the monitoring period and a delay.

The following graphic illustrates a typical communication scenario between the data logger and VCOM in which two devices (dotted lines) are not sending data to the data logger in the bus communication. In this case, two different data outage alarms will be generated for the respective devices. These alarms will be displayed in the Alarms portlet.
