CV High Limit Alarms

The module latches each bit when executing the subject profile segment in closed loop, and drives its algorithm CV to
maximum (100%) in an attempt to control the profile setpoint.
The module unlatches each bit when it completes execution of the subject profile segment in open loop, or in closed
loop without driving its algorithm CV to maximum (100%).

When this bit
is latched ON:

CV Low Limit Alarms

The module latches each bit when executing the subject profile segment in closed loop, and drives its algorithm CV to
minimum (0%) in an attempt to control the profile setpoint.
The module unlatches each bit when it completes execution of the subject profile segment in open loop, or in closed
