Hi,
I have troubles connecting the OPC SERVER from Opto22 into Ignition.
My OS: Windows 7 PRO. Java 6
Ignition : 7.3.4
OpcCom: 1.3.2 (b65)
Ignition and OpcServer runs in the same PC
The trouble:
Ignition detects my OPC Server, but dont display the tags.
Event log report: EVENT 9, OPTOOPCSERVER, There are no items in the browser database.
I used MatrikonOPC Explorer, and works ok, and no error in the event logger
In DCOM, I generate permission for EveryOne, Anonymous Logon with full permission for Opto22.OpcServer.2 and for OpcEnum
Thanks for your Help

Hi,
I suspect that the problem is caused by the fact that Ignition runs as a service, under the System account. From that error, it seems possible that when Ignition tries to connect, instead of connecting to the running server, a new instance is created behind the scenes, without the proper configuration. The Matrikon client is running under the interactive account, and therefore connects to the Opto22 instance running there.
Try this:
- Change the Ignition service to run as a user account. Go to Services, and then Properties for Ignition. On the “Log On” tab, change it to run as a different account.
- Change Opto22 to not run as the launching user. Run “dcomcnfg”. Browse down until you find the Opto22 opc server. Right click and select properties, and then look at the “Identity” tab. I suspect it is currently set to “the launching user”. If so, try setting it to “the interactive user”. This will force Ignition to connect to the one that is currently running (and step 1 should prevent any security problems).
Let me know if anything doesn’t seem to line up.
Regards,

Thx for your help.
You’re right. 
"Change Opto22 to not run as the launching user. Run “dcomcnfg”. Browse down until you find the Opto22 opc server. Right click and select properties, and then look at the “Identity” tab. I suspect it is currently set to “the launching user”. If so, try setting it to “the interactive user”. "
