The setpoints can be programmed via the Web Interface or communications and have the following setup
parameters:
Parameter Definition Options/*Default
Setpoint
Type
Disabled, Over or Under Setpoint.
0=Disabled*
1=Over Setpoint
2=Under Setpoint
Setpoint
Parameter
Specify the parameter to be monitored.
See Table 4-11 , 1*
Over Limit
Specify the value that the setpoint parameter must exceed for Over
Setpoint to become active or for Under Setpoint to become
inactive (Invalid if DIx is monitored).
Default=999,999
Under Limit
Specify the value that the setpoint parameter must go below for
Over Setpoint to become inactive or for Under Setpoint to become
active. (Invalid if DIx is monitored). Default=999,999
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.
0 to 9999 (s) for
Standard Setpoint, 10*
0 to 999 (Cycles) for HS
Setpoint,10*
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.
Trigger 1/2
Specify what action a setpoint would take when it becomes active.
Please refer to Table 4-12 below for a list of Setpoint Triggers.
See Table 4-12
Table 4-10 Description for Setpoint Parameters
The iMeter 6 provides the following Setpoint parameters, Standard Setpoint can monitor all parameters while
the HS Setpoint only can monitor parameters 1 to 14.
