The minimum absolute value is assigned.
Memory (optional)
With this you can undertake measured value memory settings. This config-
ures the event memory and recorder function. The device has a memory ca-
pacity of 8 MB. The memory is split into 2 areas:
Average value memory
In the average value memory, all measured and calculated values are aver-
aged and saved using the average value intervals you set. You can set
[
119] the average value intervals in stages between 1 and 40 seconds.
Event memory
Data is always saved to the event memory at the highest resolution without
first being averaged. You can also determine how much memory space is to
be made available exclusively for the event memory [
The data recorder can trigger an event depending on the undervoltage
and/or overvoltage limit value that you can set. The data recorded here are
stored in the measured value memory's event memory.
To allow instances where values exceed or fall below the limit values to be
better evaluated, the chronological sequence for the measured and calculat-
ed values also includes the last 10 seconds before values actually exceed or
fall below the limit value. Each event is saved for a maximum of 5 minutes.
When an event is active, only the chronological sequence of the measured
and calculated values is stored in the event memory.
As soon as there is no more free space in the event memory, the oldest val-
ues are overwritten by the new values measured. You can access informa-
tion about the current event memory content via the Info [
143] menu.
Data recorder
The data-recorder module can be used to save the data listed below and
display and evaluate it either on the display or using the TAPCON®-trol visu-
alization software on a PC.
