Hi Le Daniel,
I would guess that the PV is actually not being found on the network. Is EPICS_CA_ADDR_LIST set so that the IOC or CA server providing that PV can be found?
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.
