data type Description of attribute Semantics of values
3 Set NV High trip
point
INT or based
data type
attribute Defines the value at or
above which a trip point
condition will occur. → "Semantics" section below
[default = defined by vendor]
4 Set NV High trip
enable
BOOL Enables the high trip point
setting. [default = defined by vendor]
5 Set NV Low trip
point
INT or based
data type
attribute Defines the value at or be-
low which a trip point con-
dition will occur. → "Semantics" section below
[default = defined by vendor]
6 Set NV Low trip
enable
BOOL Enables the low trip point
setting. [default = defined by vendor]
7 Get V Output
Status BOOL State of this object
instance. 0 = trip point condition does not exist
(unasserted)
1 = trip point condition exists
(asserted)
12 Get NV Destination Packed
EPATH Specifies the path of the
destination attribute whose
value will be set by output. Path to attribute 3 of Instance 1 or 2
of DOP Object.
13 Get V Output BOOL Output of the object the
value of which is sent to
destination. = Status of the relay
14 Get NV Source Packed
EPATH Specifies the path of the
source attribute whose
value is retrieved for Input. Path to attribute 6 of instance 1 of S-
analog sensor object
15 Get V Input INT or speci-
fied by data
type Input to the object whose
value is retrieved from
source. Value of attribute 6 of instance 1 of S-
analog sensor object
16 Get NV Data units ENGUNITS Units of input, trip point.
17 Get NV Data type USINT Data type of input. [default] = INT
18 Set NV Trip Point
High
Hysteresis
Same as
High/Low
Point
Data
Type
Determines the amount by
which the Input must
recover to clear a trip point
high condition [default = defined by vendor]
19 Set NV Trip Point
Low
Hysteresis
Same as
High/Low
Point
Data
Type
Determines the amount by
which the Input must
recover to clear a trip point
low condition [default = defined by vendor]
20 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
4-255 = reserved
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-
lowed
