pfeifferhicube 0.1.1

Library for basic control of the Pfeiffer Vacuum HiCube Neo

PfeifferHiCube

A Python library for basic control of the Pfeiffer Vacuum HiCube Neo vacuum pump system via OPC-UA.

Usage

Connect to the HiCube Neo by providing its IP address or hostname. The recommended way is to use a with statement, which ensures the connection is cleanly closed after use:

from pfeifferhicube import HiCubeNeo

with HiCubeNeo("192.168.1.100") as cube:
    cube.evacuate()
    
    # Now both pumps of the system should be turned on
    print(cube.turbopump)   # True
    print(cube.backingpump) # True

The object can also be instantiated directly, in which case the connection is closed when the object is garbage collected:

cube = HiCubeNeo("192.168.1.100")
cube.evacuate()

Constructor Parameters

Parameter	Type	Default	Description
host	str	—	IP address or hostname of the HiCube Neo
port	int	4840	TCP port of the OPC-UA server
timeout	float	4	Timeout in seconds for server responses

Pump control

Method	Description
evacuate()	Enable backing pump and turbopump
vent()	Disable turbopump and backing pump
enable_turbopump()	Enable turbopump only
disable_turbopump()	Disable turbopump only
enable_backingpump()	Enable backing pump only
disable_backingpump()	Disable backing pump only

The pump states can also be read and set directly via properties:

cube.turbopump = True   # enable turbopump
cube.turbopump = False  # disable turbopump
print(cube.turbopump)   # read turbopump state

cube.backingpump = True   # enable backing pump
cube.backingpump = False  # disable backing pump
print(cube.backingpump)   # read backing pump state

Relay control

Method	Description
enable_relay1()	Switch relay 1
disable_relay1()	Return relay 1 to normal position
enable_relay2()	Switch relay 2
disable_relay2()	Return relay 2 to normal position

Relay states can also be read and set via properties:

cube.relay1 = True
print(cube.relay1)
cube.relay2 = True
print(cube.relay2)
