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

Pump control

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

Relay states can also be read and set via properties:

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