C.6 EXIT and EXIT_TRIGGER
A value with an EXIT ValueTag signifies that it is measured when the decision for the step transition is made.
A value with an EXIT_TRIGGER ValueTag signifies that it caused the step transition.
Example 1: Torque (used in Rundown) Step that transitions when it reaches a configured Target Torque and the Angle is monitored.
ResultValue1 (Torque):
MeasuredValue = 3.01
TargetValue = 3.0
ResultEvaluation = OK
ValueTag = EXIT_TRIGGER
HighLimit = 6.0
EngineeringUnits = Newton Metre
ResultValue2 (Angle):
MeasuredValue = 360
ResultEvaluation = OK
ValueTag = EXIT
LowLimit = 45
HighLimit = 400
EngineeringUnits = Degree
Example 2: Torque (used in Rundown) Step that exits when it violates the monitored angle and target torque is not reached.
ResultValue1 (Torque):
MeasuredValue = 0.1
TargetValue = 3.0
ResultEvaluation = NotDecidable
ValueTag = EXIT
HighLimit = 6.0
EngineeringUnits = Newton Metre
ResultValue2 (Angle):
MeasuredValue = 402
ResultEvaluation = NotOK
ValueTag = EXIT_TRIGGER
LowLimit = 45
HighLimit = 400
ViolationType = ABOVE_LIMIT
ViolationConsequence = ABORT
EngineeringUnits = Degree
