Thanks for the support.
But I am stuck at the first step that you suggested. I could not get the property change updates using 'camonitor -m p' on the command line when I change the units.
I am using EPICS base 3.14.12.5. I guess DBE_PROPERTY was introduced in 3.14.11, so it should work with 3.14.12.5. Am I missing out something?

Hello:
The support for DBE_PROPERTY has been added to CS-Studio some time ago, but that was at a time when the Channel Access gateway didn't support it, and on the IOC side basically only the 'enumeration' labels of respective record types (bi, bo, mbbi, mbbo) sent out DBE_PROPERTY updates.
What's happening is that the CA client creates two subscriptions: One for value updates, and one for property updates. If you have older IOCs or CA gateways, they won't understand the second subscription, so the client gets one error per channel from those refused subscriptions.
The DBE_PROPERTY feature has thus not been used a lot, and I must admit I've basically forgotten about it since we can't universally use it in our local setup (older IOCs, ..).
Still, fundamentally the support should be there.
Check with 'camonitor' on the command line, using the "-m p" option to monitor property changes, so assert that your record indeed sends updates when you change the units.
Then use a recent version of CSS, something with 4.2.x as a version number.
Its "diirt PVManager" is unfortunately configured via files outside of CSS.
In Edit/Preferences, look for CSS Core, Diirt preferences. You specify a Diirt configuration directory that needs to contain files like the ones found here:
https://github.com/ControlSystemStudio/org.csstudio.sns/tree/master/features/org.csstudio.sns.feature.snscore/rootfiles/diirt
Note the file datasources/ca/ca.xml, it contains a setting `dbePropertySupported` that defaults to false.
You need to set that to 'true'.
Now tools that use the "diirt PVManager" should receive monitors for property changes. This includes BOY as long as you have the Edit, Preferences, CSS Applications, Display, BOY, OPI Runtime setting for "PV Connection layer" set to "pvmanager".
If it doesn't work, we should create an issue ticket on https://github.com/ControlSystemStudio/cs-studio/issues to continue the discussion there.
Thanks,
Kay

Dear Shantonu,
The new Channel Access event type flag DBE_PROPERTY was introduced in EPICS 3.14.11, but proper support for the EPICS records is only available in the EPICS 3.15 series.
I do not have a good idea about how CS-Studio, BOY and CAJ are supporting this feature. I was prompting you for the versions, hoping that one of the CS-Studio people would pick your question up. (With the version numbers, they should be able to give an answer.)
Sorry...

I am using EPICS base-3.14.12.5, CS-Studio 4.1.4 , Java Utilities 3.2.0. I am not sure about the version of CAJ. I am not using EPICS CA Gateway.

A feature to allow such updates of metadata has been added to EPICS Base and the Channel Access protocol recently.
What versions of EPICS Base (your IOC), CS-Studio (your client) and CAJ (the Java CA client library inside CS-Studio) are you using? Is there an EPICS CA Gateway involved? (If yes, what version?)
Thanks,
~Ralph

I am using CSS-BOY to display a process variable using "Text Update". I have checked the "Show Units" property. So, in addition to the VALue, it displays the string that is specified in the EGU field of the record. But, in the runtime, if the EGU field changes, it is not updated in the OPI until I do "Refresh OPI". In contrary, the VALue is updated smoothly.
