Figure 4-2 Under Setpoint
The Setpoints can be programmed over communications and have the following setup parameters:
Setup Parameter Definition Options
Setpoint Type Specify the monitoring condition -- Over Setpoint, Under Setpoint.
0=Over Setpoint*
1=Under Setpoint
Setpoint Parameter Specify the parameter to be monitored. See Table 4-5
Setpoint Active Limit
Specify the value that the setpoint parameter must exceed for Over Setpoint
or go below for Under Setpoint for the setpoint to become active.
0*
Setpoint Inactive
Limit
Specify the value that the setpoint parameter must go below for Over Setpoint
or exceed for Under Setpoint for the setpoint to becomes inactive.
0*
Setpoint Active
Delay
Specify the minimum duration that the setpoint condition must be met before
the setpoint becomes active. An event will be generated and stored in the SOE
Log. The range of the
Setpoint Active Delay is between 0 and 9999 seconds
for Standard Setpoints and between 0 and 9999 cycles for High Setpoints.
0* to 9999s
Setpoint Inactive
Delay
Specify the minimum duration that the setpoint return condition must be met
before the setpoint becomes inactive. An event will be generated and stored
in the SOE Log. The range of the
Setpoint Inactive Delay is between 0 and
9999 seconds for Standard Setpoints and between 0 and 9999 cycles for High
Setpoints.
0* to 9999
Setpoint Trigger
Specify what action a setpoint can take when it becomes active. Please refer
to Table 4-6 below for a list of Setpoint Triggers.
