RE: camonitor not updating when PV changed

["Sobhani, Bayan" <bsobhani@bnl.gov>]

Hi Mark, I believe the epics base version is 3.14.12.6. 'which camonitor' pointed to a different /usr/bin/camonitor, but I tried running the version of camonitor in my base directory as well and I am getting the same problem.

Here is the output of cainfo Sys{Dev}OLDMOV:

Sys{Dev}OLDMOV
    State:            connected
    Host:             (I am withholding the host name just in case)
    Access:           read, write
    Native data type: DBF_LONG
    Request type:     DBR_LONG
    Element count:    1


Strangely, camonitor works fine on other PVs. It is just OLDMOV that it has this behavior.

What version of EPICS base?

 

Are you sure you are running the version of camonitor you think you are running.  Try:

 

which camonitor

 

also

 

cainfo Sys{Dev}OLDMOV

Hi, I am having a problem where I write to a PV and it is not being detected by camonitor. The PV in question is defined like this:

record (bo, "$(Sys)$(Dev)OLDMOV")
{
}

I run camonitor and see this

$ camonitor Sys{Dev}OLDMOV
Sys{Dev}OLDMOV 2018-03-28 13:09:09.227050 1

So far so good.

When I do caput Sys{Dev}OLDMOV 0, I see:
Old : Sys{Dev}OLDMOV 1
New : Sys{Dev}OLDMOV 0

However, camonitor does not update. But if I close camonitor and open it up again, it says:

Sys{Dev}OLDMOV 2018-03-28 13:23:48.628131 0

Why didn't the value on camonitor update to the correct value until I restarted camonitor?
