Experimental Physics and
Industrial Control System

Hello everybody,

 

At ESS we are seeing that the CA GW returns the first value twice when a monitor is started. I’ve seen this was discussed here more than a year ago, but no solution was found.

https://epics.anl.gov/tech-talk/2019/msg00930.php

 

I wanted to check if anybody has worked on this in the last year.

 

We see this issue with both version 2.1.1 (built with epics-base 3.16.1) and 2.1.2 (built with epics-base  7.0.4).

 

Example:

(epics) [csi@test-pvagw-client ~]$ export EPICS_CA_ADDR_LIST=test-pvagw-01.cslab.esss.lu.se

(epics) [csi@test-pvagw-client ~]$ export EPICS_CA_AUTO_ADDR_LIST=NO

(epics) [csi@test-pvagw-client ~]$ camonitor demo:bb:counter

demo:bb:counter                2020-08-27 14:37:43.995793 2

demo:bb:counter                2020-08-27 14:37:43.995793 2

demo:bb:counter                2020-08-27 14:37:45.995738 3

 

Best regards,

Juan
