V.1.11.0 installed but OPC DA datasource is not there :(
-
Succeded in some tests with this configuration:
Name and Export Id : like in all other datsourcesHost : the hostname or IP adress of the OPC server
Domain user and password : Authentification information so the client can acess the server. (I made a replication server on a Windows machine and put there a window user information )Server : If all above information is OK when you click Refresh, You will get a list of available OPC servers, then choose one.
Update periode ... I guess it is explicit.
You can now save and then press 'browse tags'
You'll then get a list of available tags.
select some of then and press 'Add Tags'
You will get Data Point for all selected tags. -
But I still have some trouble :
- the browse tag don't give me any String datatype Tag
- the browse tag don't give me any settable Tag
And I've got an OPC server functionning like that :
If I want to get the parameter X on machine Y
groupReqX settable I put value Y
groupAnsX I get the value overwise I get 0Is there any way to do that ? how ? scripting?

For other question from you I don't have an answer but I also waiting an answer for settable value issue...
-
Mango is on a virtual Linux box so I can't answer for the localhost.
Maybe You could try with the box IP or 127.0.0.1 instead of localhost.I tried to let domain blank and it worked fine.
-
I used localhost and it worked fine.

Tried to add manually (with the import feature) a data point type string like that :
{ "dataPoints":[ { "xid":"DP_999323", "loggingType":"ON_CHANGE", "intervalLoggingPeriodType":"MINUTES", "intervalLoggingType":"INSTANT", "purgeType":"YEARS", "pointLocator":{ "dataType":"ALPHANUMERIC", "settable":false, "tag":"PCC1.AR01.A0_ssys_ddmmyy00" }, "eventDetectors":[ ], "engineeringUnits":"", "chartRenderer":null, "dataSourceXid":"DS_691328", "defaultCacheSize":1, "discardExtremeValues":false, "discardHighLimit":0.0, "discardLowLimit":0.0, "enabled":true, "intervalLoggingPeriod":15, "name":"PCC1.AR01.A0_ssys_ddmmyy00", "purgePeriod":1, "textRenderer":{ "type":"PLAIN", "suffix":"" }, "tolerance":0.0 } ] }
I get 'Unknown value type' so it find the Tag (would get a 'Unknow Tag' overwise) but can't do anything with the answer.

I was able to import this point, but of course, it says that it was unable to add the point because i don't have it. If you know you have that point on your server, i think someone from ScadaBR will need to comment. They're the experts on it.

Any doubt about OPC Configuration please take a look:
http://sourceforge.net/projects/scadabr/files/Software/Docs/OPC Configuration ScadaBR.pdf
The configurations about OPC DataSource refers only to the server, in other words, all the settings must be about where OPC Server is located.
A important note: The computer where is the Server must contain a domain.

Yes, I got mine working with a computer which is part of a domain. But same notice as "Patriator" has: Settable values shows "false" even if I know that OPC Server tag is writable one.
Maybe have to just wait some improvements from ScadaBR, "mlohbihler"?

Hi again,
ScadaBR team made some improvements about OPC Client and i believe that
within a maximum a week they are passed for Mango. -
Hello
rbautomacao has updated the opc-driver.jar
it can be found here:
https://scadabr.svn.sourceforge.net/svnroot/scadabr/ScadaBR/WebContent/WEB-INF/lib/opc-driver.jarplease try this new version and let us know if the fixes are ok.
thanks! :)

Just tried this new jar.

Yes, now it's works!
I did not made any further checking but anyway direction is right!
Hopefully development does not end and soon we will see also settable polling periods for individual points etc. OPC Client things...
