7.6.9. Power Fail
Working with an external 12 V backup battery, the RTU informs you when the main voltage is out of order
and the RTU is powered from the 12 V backup battery. An internal DI variable informs that the main power
broke down.
Example from the LT2-542-3:
From the list of DI available with the card, you Tag the one indicating the Power Failure (DI.0.1.0)
From the RTU properties:

Advanced

tab “Power Fail”
you select the Tag
corresponding to the Power
Failure (see above)
This power fail information will then condition the execution of alarm and chronology condition where
you have specified a handling associated to “Power Failure”: in case of power failure, alarm and chronology
conditions will not be executed (see chapters related to Alarm and Chronology conditions further in the
manual).
In addition, the above Tag (in this example “PowerFail”) can be used to send an alarm and can be recorded
into chronologies (datalogging).
7.6.10. Web and Report
Check user's WebFormViewer version: This option concerns WebForm 1.0 only. (this service is not
supported anymore)
Unique Report file name format: When sending a report by FTP, you have the choice of sending the report
with ‘Unique file name’ (see Report Studio

report properties

Advanced). In this case,
the RTU includes supplementary parameters in head of the name of the report.
