The Trip Point Object models the action of trip points (two relays) of the CDG
(corresponding to physical outputs) (Discrete Output Object). A trip point value,
designated as a high or low trip point, is compared to the specified source value.
This trip point is intended to be used as a process control indicator.

data type Description of attribute Semantics of values
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] = 0
6 Get NV Low trip
enable
BOOL Enables the low trip point
setting. [default] = 0
7 Get V Status BOOL State of this object
instance. 0 = trip point condition does not exist
(unasserted)
1 = trip point condition exists
(asserted)
10 Set NV Hysteresis Same as
high/low point
data type
Determines the amount by
which the input must re-
cover to clear a trip point
condition. → "Semantics" section
[default] = 0
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
101 Set NV Percentage
of ATM REAL Multiplier for ATM control. If high trip point enabled, this value
will be multiplied with pressure value
from S-Analog sensor instance 2
(ATM sensor) copied into trip point
high
102 Get V High trip
point
INT or based
data type
attribute Defines the value at or
above which a trip point
condition will occur. [default] = 0
103 Get NV High trip
enable
BOOL Enables the high trip point
setting. [default] = enabled
