Select the tab Restore trigger and energy flow direction and enter the restore
trigger and energy flow direction.
Select the Cyclic option if the metered value is to be transmitted to the control center
at cyclic intervals. Otherwise select the None option. By pressing the Settings button,
you end up in the dialog box for setting the corresponding time interval. One minute
is preset.
Note
The settings made in the Cyclical restoring tab apply globally for all metered values.
Under Energy flow direction, you define whether the metered value summates the
quantity of exported or imported energy by selecting one of the two options.

Select the tab Pulse type and error input and make your settings there.
Select the Wiping pulse / S0 option if the rising edge of a single pulse is to increment
the metered value by one. Select the Double current pulse option if the falling edge
of a double current pulse is to increment the metered value by one.
As soon as you route a pulse metered value to a binary input, the next binary input can
be automatically routed as an fault input. A signal to this fault input can mark the count
as corrupt. If you use this procedure, select the Use fault input checkbox. If it is not
selected, the binary input following the metered pulse input is available to another
application.
