Get
V Trip Status USINT
Describes the activator for
the trip point condition.
Activator may be a
High Trip Point condition
and/or a Low Trip Point
condition.
0 = no trip point condition exists
1 = low trip point condition exists
2 = high trip point condition exists
3 = high and low trip condition exist

101 Set
NV
Factor
of
ATM
REAL
Multiplier for ATM control
If with the Attribute 102 the amt mode
is chosen, this value will be multiplied
with pressure value from S-Analog
Sensor Instance 3 (ATM sensor) and
copied into High or Low Trip Point
(
→ Attribute 102).
102 Set
NV
Setpoint
Mode
USINT
Mode of the setpoints
Atm Mode,
0 = standard setpoint
1 = LTP is in ATM Mode
2 = HTP is in ATM Mode
3 = LTP and HTP are in ATM Mode
4 … 7 = the same as 0 … 3, but the
change with push-buttons isn't al-
