can be defined. Depending on the trigger data point type, the trigger conditions can be
refined.
Note, that the behavior of the trigger data point is influenced by the COV properties of the
data point. If the
Only notify on COV
property is checked, the data point triggers only if
its value changes to the value of the trigger condition. If that property is not checked, the
data point triggers on every write with a value that matches the trigger condition.

10.12.4 Deliver Trend Data via E-mail
Trend logs can be downloaded from the device via file transfer. This requires an active
action by the user. Alternatively, trend data can be sent as an e-mail attachment. For doing
that, an e-mail template has to be setup for the trend log to be transmitted. The fill-level
condition in the trend object can be used as a trigger to send an e-mail with the trend’s data
logger CSV file as an attachment.
For setting up e-mails, the account information has to be configured on the device, e.g., on
the web UI. Then an e-mail template can be created and the trend object attached as a
trigger.
To Create an E-mail Template for Trends
1.
Create or configure an e-mail template.
2.
Change to the
Mail Triggers
tab.
3.
Click the
Add…
button and select a trend object.

Fill Level
condition.
