Alarms

You can define custom alarm-conditions to monitor the uploaded data. Whenever these conditions are violated DaqMon will create an Annotation and will send an e-mail (when configured to do so).

Simple Conditions

For simple conditions every data sample is checked against the alarm condition.
e.g. activate an alert when the temperature raises over 60°C

Threshold

Greater-Than

The alert is activated when the data is greater than the threshold level.
The alert is deactivated when the data falls below the threshold again.

Lower-Than

The alert is activated when the data is lower than the threshold level.
The alert is deactivated when the data goes above the threshold again.

Range

Inside-Range

The alert is activated when the data enter the range.
The alert is deactivated when the data leaves the range again.

Outside-Range

The alert is activated when the data leaves the range.
The alert is deactivated when the data enters the range again.

Conditions with Duration

The conditions are the same as the simple conditions, but you can also define a duration.
e.g. activate an alert when the temperature is over 60°C for more than 2 hours.

Greater-Than with Duration

On

The alert is activated, because the data is greater than the threshold level for the specified duration.

Off

In this example, the data is higher than the threshold, but not for long enough, so the alarm remains off.

Lower-Than with Duration

On

The alert is activated, because the data is lower than the threshold level for the specified duration.

Off

In this example, the data is lower than the threshold, but not for long enough, so the alarm remains off.

Range-Inside with Duration

On

The alert is activated because the data entered the range for longer than the specified duration.
The alert is deactivated when the data leaves the range again.

Off

In these examples, the data has entered the range, but not for long enough, so the alarm remains off.

Range-Outside with Duration

On

The alert is activated because the data left the range for longer than the specified duration.
The alert is deactivated when the data enters the range again.

Off

In this example, the data has left the range, but entered the range again before the duration.

Complex Alarms

You can use Math channels to create complex alarm conditions.

For example, let’s assume you have Thermo A1 and Thermo A2, and you want to get an alarm when the difference between those channels is higher than 20°C.
Just define a Math channel that calculates the difference between the channels:
abs(Thermo_A1- Thermo_A2)
and create a simple alarm to check that it is <= 20.

Uploader Alarms

In addition to monitoring the uploaded data, you can also monitor the connection to your Uploader programs and servers.
E.g. you can configure DaqMon to send an e-mail when an uploader does not send any request for a certain duration (e.g. 1 hour).
