Re: CSS version 4.2: can't access EPICS

[marcus.michalsky@ptb.de]

Hello,

AFAIK CS-Studio 4.2.0 uses Diirt 3.0,
changing the way how PV Access is configured.

In CS-Studio 4.1 and before you had
a configuration based on Eclipse Preferences (with plugin_customization.ini).
 
The new Version (Diirt) uses an XML
File for Configuration. The Preferences in Eclipse now only define where
to find these XML file(s).

See https://github.com/diirt/diirt/wiki/Diirt-Configuration

Your problem now is that in your old
version you had defined "CA" as your default datasource, meaning
all your PV Definitions got a "ca://" prefix.
The new Version does not find a configuration
xml and thus there is no "default data source". So no "ca://"
is added to you PV strings automatically anymore. 

You can try adding "ca://"
in front of one of your PV Strings. If this works you can create a diirt
XML config defining CA as your default data source.

4.2: can't access EPICS

I updated my CS-Studio to version 4.2.0 (I downloaded
the executable).
Now I find that I can't access any EPICS PVs.  My screens show the
PVs as 'disconnected', yet I can access them using caget.
Probe says that "Channel <PV name> uses default data source
but one was never set"
The css_book at https://ics-web.sns.ornl.gov/kasemir/CSS/Training/css_book.pdf
says ($27.3) to check that I have a plugin called org.csstudio.utility.pv.epics. 
I don't, but unfortunately it doesn't tell me what I can do about that...
(I _do_ have org.csstudio.platform.libs.epics).
Under Edit...Preferences...CSS Core I was hoping to find an EPICS section
so that I could check my settings corresponding to EPICS_CA_ADDR_LIST etc. 
Unfortunately, the entire EPICS section is missing.

Any ideas?

Phil
