I am trying to communicate with TTi power supply model QPX1200SP through ethernet connection.

Here is my script:

import pyvisa as visa
rm = visa.ResourceManager()
print(rm.list_resources(query='TCP?*')) #specific query for anything over Ethernet

#above line gives me an answer ('TCPIP0::10.10.0.27::9221::SOCKET',), so line below:

ttipsu = 'TCPIP0::10.10.0.27::9221::SOCKET'

psu = rm.open_resource(ttipsu)

I receive a traceback:

File C:PythonLibsite-packagesspyder_kernelspy3compat.py:356 in compat_exec

raise errors.VisaIOError(rv)

VisaIOError: VI_ERROR_RSRC_NFOUND (-1073807343): Insufficient location information or the requested device or resource is not present in the system.

I also tried it with line:

rm = visa.ResourceManager('C:\Windows\System32\visa64.dll')

I can ping the 10.10.0.27 with success, 2ms, 0% loss.

What seems to be a problem here?
