Description
HI
x > A
The event occurs when the value of the assigned process variable (x) is
greater than the setpoint (Setpoint A), endpoint not included.
The event occurs when the value of the assigned process variable (x) is
greater than the setpoint (Setpoint A), endpoint not included.
LO
x < A
The event occurs when the value of the assigned process variable (x) is
less than the setpoint (Setpoint A), endpoint not included.
The event occurs when the value of the assigned process variable (x) is
less than the setpoint (Setpoint A), endpoint not included.
IN
A ≤ x ≤ B
The event occurs when the value of the assigned process variable (x) is
“in range,” that is, between Setpoint A and Setpoint B, endpoints included.
The event occurs when the value of the assigned process variable (x) is
“in range,” that is, between Setpoint A and Setpoint B, endpoints included.
OUT
x ≤ A or x ≥ B
The event occurs when the value of the assigned process variable (x) is
“out of range,” that is, less than Setpoint A or greater than Setpoint B, end-
points included.
The event occurs when the value of the assigned process variable (x) is
“out of range,” that is, less than Setpoint A or greater than Setpoint B, end-
points included.
3.
Assign a process variable to the event.
4.
Set values for the required setpoints.
•
For HI and LO events, set Setpoint A.
•
For IN and OUT events, set Setpoint A and Setpoint B.
5.
(Optional) Configure a discrete output to switch states in response to the event
status.
