I have enabled VI server. Please go through the scrpit below. With this I m getting error in the VIpath line itself. If I am able to get reference to it, I can read back the values.
from ctypes import *
import comtypes.client
comtypes.CoInitialize()
TypeLibPath = "C:/Program Files (x86)/National Instruments/LabVIEW 2010/resource/labview.tlb"
# Attention: For unknown reason first attempt of type library import via
# GetModule() fails if comtypes.client.gen_dir is set to a directory.
# Solution: Set it to none so all imported data is kept only in memory.
comtypes.client.gen_dir = None
comtypes.client.GetModule(TypeLibPath)
try:
Application = comtypes.client.CreateObject("LabVIEW.Application", None, None, comtypes.gen.LabVIEW._Application)
#Parameters
Channel_1=[1,2,3]
Channel_2=[8,9,10]
Data=[Channel_1,Channel_2]
Read="FALSE"
ParameterNames=("Data","Read")
Parameters=[Data,Read]
VIPath="C:\Users\i14301\Desktop\Labview_from_Python\ComplexData.exe"
#Get VI Reference
VirtualInstrument = Application.GetVIReference(VIPath)
#Open VI front panel in hidden mode
VirtualInstrument.OpenFrontPanel()
#Call VI
print ("Calling LabVIEW VI\n")
VirtualInstrument.Call(ParameterNames,Parameters)
DataOut = VirtualInstrument.GetControlValue("DataOut")
print('Output =')
print(DataOut)
except:
VirtualInstrument = None
Application = None
# rethrow the exception to get the full trace on the console
raise
VirtualInstrument = None
Application = None
