However, in the process of testing it, it was found that only a single PV can be monitored

In p4p can’t you just call the monitor() method multiple times, once for each PV that you want to monitor?

In pvapy can’t you just create a Channel object for each PV, and call it’s monitor() method?

Hi EPICS community, I am trying to monitor several EPICS7 PVs using pvapy or p4p. pvapy and p4p are described below:

http://epics-pvdata.sourceforge.net/docbuild/4.7.0/pvaPy/

https://mdavidsaver.github.io/p4p/

However, in the process of testing it, it was found that only a single PV can be monitored.The method of connecting to multiple PV is multiChannel,but there is only get(),  no monitor method. What method can be used to monitor a large number of PV?

Best regards,
Sky Qin
