HT/NT tariff changeover
If the
digital input 1
assigned to function "5"
one can change between low and high tariff
using the input. If there is no voltage at the in-
put, a 0 is written to address 071. If there is
voltage at the input, a 1 is written to address
071.
If the
digital input 2
assigned to function "5"
one can change between low and high tariff
using the input. If there is no voltage at the in-
put, a 0 is written to address 072. If there is volt-
age at the input, a 1 is written to address 072.
Adr.071=0; real energy counter low tariff active.
Adr.071=1; real energy counter high tariff active.
Adr.072=0; reactive energy counter high tariff
active.
Adr.072=1; reactive energy counter high tariff
active.
Adr.002=5; Digital input 1 is used for high/low
tariff changeover for real energy.
Adr.002=6; Digital input 1 is used for high/low
tariff changeover for real and
reactive energy.
Adr.003=5; Digital input 2 is used for high/low
tariff changeover for reactive
energy.
Adr.003=6; Digital input 2 is used for high/low
tariff changeover for real and
reactive energy.
Only the inductive reactive energy is used for
the counters high and low tariff. If no changeover
is programmed, the induktive energy is saved on
address 426 and the capazitive energy on
address 428.
Only the consumed real power is used for the
counters high and low tariff. If no changeover is
programmed, the consumed real energy is
saved on address 422, and the supplied real
energy on address 424.
Changeover is not possible via Profibus.
