Lauda thermostats¶

This is the basic Python class to control Lauda thermostats over EPICS.

Using EPICS Lauda thermostats module¶

Usage of Python class for EPICS Lauda thermostats.

class py4syn.epics.LaudaClass.Lauda(pvName, mnemonic)[source]¶

Class to control Lauda temperature controllers via EPICS.

Examples

>>> from py4syn.epics.LaudaClass import Lauda
>>>    
>>> def showTemperature(pv):
...    lauda = Lauda(pv, 'lauda')
...    print('Temperature is: %d' % lauda.getValue())
...
>>> def setTemperature(lauda, temperature):
...    lauda.setValue(temperature)
...    lauda.run()

Constructor See py4syn.epics.StandardDevice

Parameters:	pvName : string Power supply base naming of the PV (Process Variable) mnemonic : string Temperature controller mnemonic

changePump(val)[source]¶

Same as setPumpSpeed().

See setPumpSpeed()

Parameters:	val : int The requested pump speed.

changeSetPoint(val)[source]¶

Same as setValue().

See setValue()

Parameters:	val : int The requested temperature.

getExternalTemp()[source]¶

Returns the device’s external temperature.

Returns:	`int`

getHighLimitValue()[source]¶

Returns the controller high limit temperature.

Returns:	`int`

getInternalTemp()[source]¶

Same as getValue().

See getValue()

Returns:	`int`

getLevel()[source]¶

Returns the device’s bath level.

Returns:	`int`

getLowLimitValue()[source]¶

Returns the controller low limit temperature.

Returns:	`int`

getOverTemp()[source]¶

Returns the maximum temperature software defined limit.

Returns:	`int`

getPower()[source]¶

Returns the current device power.

Returns:	`int`

getRealPosition()[source]¶

Returns the same as getValue().

See: getValue()

Returns:	`int`

getSetPoint()[source]¶

Returns the current target temperature.

Returns:	`int`

getStatus()[source]¶

Returns the device status word.

Returns:	`int`

getTN()[source]¶

Returns:	`int`

getThermoStatus()[source]¶

Returns the device thermostat error word.

Returns:	`int`

getValue()[source]¶

Returns the current measured temperature.

Returns:	`int`

onTemperatureChange(**kwargs)[source]¶: Helper callback that indicates when the measured temperature changed.

run()[source]¶: Starts or resumes executing the current temperature program.

setPumpSpeed(speed)[source]¶

Changes the pump speed.

Parameters:	speed : int The requested pump speed, ranging from 1 to 8.

setValue(v)[source]¶

Changes the temperature to a new value.

Parameters:	v : int The target temperature in °C

setVelocity(r)[source]¶

Dummy method setVelocity()

Parameters:	r : float Ramp speed in °C/min

start()[source]¶

Same as run().

See run()

stop()[source]¶: Stops executing the current temperature program and puts the device in idle state. In the idle state, the device will not try to set a target temperature.

wait()[source]¶: Blocks until the requested temperature is achieved.
