9.2 Storage of »VisiWinNET® Smart« visualisation data
The Controllers 3231 C cyclically store »VisiWinNET® Smart« visualisation data (user-specific trends,
alarms, recipes) every 60 seconds.
In the event of a voltage failure, the Controllers 3241 C store the »VisiWinNET® Smart« visualisation
data (user-specific trends, alarms, recipes) exactly isochronously to the SD card.
In the event of a voltage failure, the Controllers c300/p300/p500 store the »VisiWinNET® Smart«
visualisation data (user-specific trends, alarms, recipes) exactly isochronously to the memory card.
This is made possible by the high-capacity, integrated UPS.

Note!
Controller 3231 C:
Depending on the time of occurrence of the voltage failure, the data saved last may be
out-of-date by up to one minute.
There is a time period of one minute between two storage processes. Hence, the saved
visualisation data is not exactly up-to-date after a voltage failure.
