Meter reading

For each output, there is a meter and a flexibly parameterized intermediate meter for detection of the ac-
tive energy consumption of the connected loads in Wh. The three meters of outputs A, B and C are added
to give the Meter total, for which an intermediate meter is also available.
The general settings for all meters are made in the parameter window
ter reading total (Wh) is also enabled here. In parameter window
mediate meters for the respective outputs are enabled.
In "normal" operation, the intermediate meters can be reset via 1 bit communication objects or defined
events (Trigger 1, see below). If the main meter is also to be reset in exceptional cases, this can be under-
taken using communication objects no. 11 and 12 (Enable reset meters and Reset meter readings). All
main and intermediate meters are then stopped and reset.
The meter readings of the main meters (outputs A...C and total) can be sent cyclically and on request.
They are buffered both in the event of mains voltage failure as well as bus voltage failure.
Functionality and configuration of the intermediate meters (Intermediate meter total and intermediate meter
output) are always fundamentally the same. The only difference is: On the intermediate meters for the out-
puts, in contrast to the Meter reading total, the output can switch on or off depending on different events.
