Experimental Physics and
Industrial Control System

Dear colleagues,

We have a new computer installation (Windows 10) with epics 7.0.4, python 3.6.4. When I try to connect with caget() directly over the command line to access a device, e.g.

Caget XXXX:XXXX:firmwarebuilddate

It immediately works.

When using pyepics over pycharm, or the python interpreter, the message „cannot connect to DEVICE“ is given out.

The Windows path variables are set, EPICS_CA_ADDR_LIST is set and imported into the pycharm environment.

In both pycharm and python console if I do the following:

import epics
import os
from epics import PV, caget, caput, cainfo
os.environ['EPICS_CA_ADDR_LIST'] = 'XXX.XXX.XXX.XXX'
os.environ['EPICS_CA_AUTO_ADDR_LIST'] = 'NO'
print(caget('XXXX:XXXX:firmwarebuilddate'))

The same error occurs.

I’d kindly ask for your help.

Thank you

Kind wishes

Thomas
