hvl_ccb.dev.technix.device

The device class Technix and its corresponding configuration class

class Technix(com, dev_config)

Bases: SingleCommDevice

Device class to control capacitor chargers from Technix

static config_cls()

Return the default configdataclass class.

Returns

a reference to the default configdataclass class

property current: Optional[Union[int, float]]

Actual current of the output in A

default_com_cls() → Union[Type[TechnixSerialCommunication], Type[TechnixTelnetCommunication]]

Get the class for the default communication protocol used with this device.

Returns

the type of the standard communication protocol for this device

property inhibit: Optional[bool]

Is the output of the voltage inhibited? The output stage can still be active.

property is_started: bool

Is the device started?

property max_current: Union[int, float]

Maximal output current of the hardware in A

property max_voltage: Union[int, float]

Maximal output voltage of the hardware in V

property open_interlock: Optional[bool]

Is the interlock open? (in safe mode)

property output: Optional[bool]

State of the high voltage output

query_status(*, _retry: bool = False)

Query the status of the device.

Returns

This function returns nothing

property remote: Optional[bool]

Is the device in remote control mode?

start()

Start the device and set it into the remote controllable mode. The high voltage is turn off, and the status poller is started.

property status: Optional[_Status]

The status of the device with the different states as sub-fields

stop()

Stop the device. The status poller is stopped and the high voltage output is turn off.

property voltage: Optional[Union[int, float]]

Actual voltage at the output in V

property voltage_regulation: Optional[bool]

Status if the output is in voltage regulation mode (or current regulation)

class TechnixConfig(communication_channel: Union[Type[hvl_ccb.dev.technix.base.TechnixSerialCommunication], Type[hvl_ccb.dev.technix.base.TechnixTelnetCommunication]], max_voltage: Union[int, float], max_current: Union[int, float], polling_interval_sec: Union[int, float] = 4, post_stop_pause_sec: Union[int, float] = 1, register_pulse_time: Union[int, float] = 0.1, read_output_while_polling: bool = False)

Bases: object

clean_values()

Cleans and enforces configuration values. Does nothing by default, but may be overridden to add custom configuration value checks.

communication_channel: Union[Type[TechnixSerialCommunication], Type[TechnixTelnetCommunication]]

communication channel between computer and Technix

force_value(fieldname, value)

Forces a value to a dataclass field despite the class being frozen.

NOTE: you can define post_force_value method with same signature as this method to do extra processing after value has been forced on fieldname.

Parameters

• fieldname – name of the field

• value – value to assign

is_configdataclass = True

classmethod keys() → Sequence[str]

Returns a list of all configdataclass fields key-names.

Returns

a list of strings containing all keys.

max_current: Union[int, float]

Maximal Output current

max_voltage: Union[int, float]

Maximal Output voltage

classmethod optional_defaults() → Dict[str, object]

Returns a list of all configdataclass fields, that have a default value assigned and may be optionally specified on instantiation.

Returns

a list of strings containing all optional keys.

polling_interval_sec: Union[int, float] = 4

Polling interval in s to maintain to watchdog of the device

post_stop_pause_sec: Union[int, float] = 1

Time to wait after stopping the device

read_output_while_polling: bool = False

Read output voltage and current within the polling event

register_pulse_time: Union[int, float] = 0.1

Time for pulsing a register

classmethod required_keys() → Sequence[str]

Returns a list of all configdataclass fields, that have no default value assigned and need to be specified on instantiation.

Returns

a list of strings containing all required keys.
