This is the basic Python class to control the Lake Shore 331 temperature controller over EPICS.
Using EPICS Lake Shore 331 module¶
Usage of Python class for EPICS Lake Shore 331.
-
class
py4syn.epics.LakeShore331Class.LakeShore331(pvPrefix='', mnemonic='', channel=0)[source]¶ Python class to help configuration and control of LakeShore 331 devices via Hyppie over EPICS.
Examples
>>> from py4syn.epics.LakeShore331 import LakeShore331 >>> ls331 = LakeShore331("DXAS:LS331", "ls331", channel=0) # Use 1 for Ch B >>> ls331.setValue(120) # 120 degrees Celsius
Constructor See
py4syn.epics.StandardDeviceParameters: - pvPrefix : string
LakeShore331’s device base naming of the PV (Process Variable); Like DXAS:LS331;
- mnemonic : string
LakeShore331’s mnemonic
