The following table describes the attributes used by the Tower Sequencing-Vernier modules:

Table 1. Tower Sequencing-Vernier Attributes
Name	Description	Default Value
Control Status	Indicates the status of the PID that controls the stages.	Normal Set Name: Control Status
Device X Enable (Where X Is 1-12)	Enables the stage to be a part of the control strategy.	False Boolean
Device X Out (Where X Is 1-12)	Commands the fan to run or not.	False Boolean
Device X Runtime (Where X Is 1-12)	Indicates the device’s current runtime value.	0
Minimum Off Time	Indicates the minimum time a stage is held off.	15 Display Units: Seconds
Minimum On Time	Indicates the minimum time a stage is held on.	15 Display Units: Seconds
Mode	Enables the staging process to run using an Off/On command.	Off Set Name: Off/On
Output (Float)	Indicates the output for the vernier stage to be controlled proportionally.	0 Display Units: %
Output Overridden	Indicates when the actual output that is controlled by this output controller is overridden by a user.	False
Output Position	Provides the current Present Value of the output that this controller drives.	0.0 Display Units: %
PID Tuning Reset	Causes the PID objects to reset their tuning parameters to the default based on the appropriate Process ID.	Normal Set Name: PID Tuning Reset
Process Units	Rotates the lead of the stages, when True, starting with the one that has the lowest runtime.	°F Set Name: Unit
Process Variable	Determines whether Stage Up or Stage Down is required and is the variable that is compared to the setpoint.	100 Display Units: °F
Rotate Now	Indicates the target value of the process variable.	False Boolean
Setpoint	Indicates the target value of the process variable.	95 Display Units: °F
Rotate Now	Indicates the target value of the process variable.	False Boolean
Setpoint	Indicates the target value of the process variable.	95 Display Units: °F

¹ C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
