Hello, I’m using a raspberry to get epics variable value from that code : import epics import time while True: p=epics.PV(‘TL_AN_Input’) val = p.get() print (val) time.sleep(0.1) This code runs about 10 seconds and after it returns the error message : /home/pi/.local/lib/python3.9/site-packages/epics/ca.py:1528: UserWarning: ca.get(‘TL_AN_Input…’) timed out after 1.00 seconds. Warnings.warn(msg % (name(chid), timeout)) What does it mean ? Is it because I need to clean the PV_cache ?
è if it is the case how can I do that ? Thank you very much. Cordialement, LE DANIEL Erwann. CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.
