Class Description
The undulator class for the Petra3 beamlines implements the basic parameters (gap, taper, velocity) to drive an undulator from a beamline. It also handles the state and disables the access in case of a local usage or an exclusive usage by the acceleraor control room. <p> The undulator control is handled by a Tine device in the accelerator control system. The Tine device has to be mapped into a Tango device by the Tine To Tango Gateway (TTTGW class). You have to specify the name of a TTTGW device for every device of this class. </p> <p> The Tine undulator device has many more attributes and shows the hardware state via a control byte and a status byte. <br /> Control byte information: </p> <p> bit 1 (0x2) = set when vacuum interlock OK <br /> bit 2 (ox4) = set when beamline access enabled </p> <p> Status byte information: </p> <p> 1 - local control for comissioning <br /> 5 - Undulator moves <br /> 6 - Undulator ready to move <br /> 7 - Error detected by local control, try to reset <br /> 10 - local control is switched off <br /> 27 - Undulator is ready to move, but an incoherent read and set value was detected </p>

Attributes:
| Name | Description |
|---|---|
| GapTargetScalar: DevFloat | The gaptarget of the undulator. |
| TaperTargetScalar: DevFloat | The tapertarget on the undulator. |
| GapScalar: DevFloat | The gap of the undulator. |
| TaperScalar: DevFloat | The applied taper on the undulator. |
| VelocityScalar: DevFloat | The moving velocity of the undulator gap in % of the\nmaximum velocity. Limited to 33%. |
| PositionScalar: DevDouble | Moves the gap by setting the energy. |
| HarmonicScalar: DevLong | Harmonic to be used in the relation between gap and energy.\n0-> take automatically the lowest odd possible harmonic. |
| PositionSimScalar: DevDouble | — |
| UnitLimitMaxScalar: DevDouble | — |
| UnitLimitMinScalar: DevDouble | — |
| GapOffsetScalar: DevFloat | — |
| SetHarmonicAutomaticallyScalar: DevLong | Set to 1 for changing the harmonic automatically depending on the energy. |
| HarmonicSimScalar: DevLong | Harmonic to be used in the relation between gap and energy for the simulaton mode. 0-> take automatically the lowest odd possible harmonic. |
| ResultSimSpectrum: DevString | — |
| RecentWritesSpectrum: DevString | Stores the recent output operations. |
Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State State Code |
This command gets the device state (stored in its <i>device_state</i> data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Status description |
This command gets the device status (stored in its <i>device_status</i> data member) and returns it to the caller. |
| CalibrateInput: DevDouble Real position Output: DevLong Complation status |
— |
| ResetMotorInput: DevVoid Output: DevVoid |
Reset a hardware fault. |
| StopMoveInput: DevVoid Output: DevVoid |
Stop a gap or taper movement. |
| StartMoveInput: DevVoid Output: DevVoid |
Start a gap or taper movement. |
Pipes:
Properties:
| Name | Description |
|---|---|
| TTTGW_NameDevString | The name of the Tine device for the undulator. The Tine devices should be mapped automatically into Tango devices by the TTTGW (Tine To Tango GateWay) class with the same name. The Undulator class will acess the device of the Tine To Tango Gateway. |
| PTTGW_NameDevString | The name of the plc device for the undulator. |
| BeamlineDevLong | Beamline number. Set in Branch property A or B if there are two undulators, by default A |
| LockTimeMsDevFloat | After sending a StartMove command, the state will be locked to MOVING for `LockTimeMs` milliseconds. This is to avoid state oscillations if the actual start of the move takes some time. |
| BranchDevString | Property for distinguish undulator A or B for beamlines with boths. |
