Chapter 5 Setpoint Programming and Operation
You may read setpoint output flags in the Discrete Data table on
page 193 and the Remote I/O, DeviceNet, EtherNet/IP and ControlNet
I/O Messaging Parameters on page 191 . You may read only the first 8
setpoint output flags in the discrete input table with optional remote
I/O communication.
Setpoints evaluate data based on six different conditions: over
forward, over reverse, under forward, under reverse, equal, and not
equal. Over and under setpoint evaluation conditions may only be
used with analog values such as voltages, currents, power, etc.
Reverse setpoints are typically used to monitor power and energy
when on-site generation is present. Equal and not equal evaluation
conditions are for use with discrete conditions such as phase rotation,
status inputs and transient detection.
Over Forward Setpoint
An over forward setpoint activates when the magnitude of the
parameter being monitored (defined by the Setpoint Type) increases
beyond the Setpoint High Limit and remains over the limit for a time
greater than the Setpoint Action Delay. The setpoint releases when the
magnitude of the parameter being monitored decreases below the
Setpoint Low Limit and stays below the limit for a time greater than
the Setpoint Release Delay.
Over Forward Setpoint Operation
TIP
If more than one setpoint is used to control the relay and/or KYZ
output, the individual setpoints are evaluated in a logical and to
determine the output state.
