Attributes:

Name Description
ComputedVoltageScalar: DevFloat Voltage to be sent to the power supply for the ResistanceSet value.
DifferentialParScalar: DevDouble DIfferential parameter for voltage calculation.
ProportionalParScalar: DevDouble Proportional parameter for voltage calculation.
IntegralParScalar: DevDouble Integral parameter for voltage calculation.
StartIntegralValueScalar: DevDouble Start value for the integral used in voltage calculation, it is updated every time a new value is computed.
PositionScalar: DevDouble Resistance to be set (used in the calculation of the voltage to be sent to the power supply), A loop trying to set this resistance is stared.
UnitLimitMaxScalar: DevDouble
UnitLimitMinScalar: DevDouble
ActiveScalar: DevDouble 1 if the control thread is running.
LoopTimeScalar: DevDouble Cicle time for regulating the temperature.
KeithleyValueScalar: DevDouble Value read from the selected Keithley channel
MaximumComputedVoltageScalar: DevDouble Maximum voltage to be sent to the power supply for the ResistanceSet value.
ContinuousModeScalar: DevLong If 1, measurements in Keithley are done continuously. If 0, comannds SetMeasurement and StartMeasurement of the Keihtley are called at each loop step.

Commands:

Name Description
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StopMoveInput: DevVoid
Output: DevVoid
Makes nothing, only for compatibility.
CalibrateInput: DevDouble
Output: DevVoid
Only for compatibility reasons. It does nothing.
ResetMotorInput: DevVoid
Output: DevVoid
Only for compatibility reasons. It does nothing.
StopTempCtrlLoopInput: DevVoid
Output: DevVoid
Stops thread for the temperature control, and with that the measurements with the keithley.
