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. |
| LimitIntegralValueScalar: DevDouble | Max value allowed to the integral part of the calculation. |
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. |
