The relay to which the alarm was assigned during I/O
setup will be displayed as read-only information.
Enter the measured variable or computed value to be
alarmed.
Indicate whether this is a high or low alarm.
Enter the setpoint value at which the alarm will become
active.
Specify the deadband. Once the alarm is active, it will not
deactivate until the alarmed variable differs from the
setpoint by at least the value of the deadband.
