Hello,
Your configuration is correct.

What data are received from CoDeSys OPC by Matrikon OPC client?

The possible cause of the issue that processes of OPC server and Communicator uses different Windows users. Try the advice from http://doc.rapidscada.net/content/en/use-cases/opc-standard.html (scroll to the end of the article)

Hi Mikhail,
In Matrikon OPC client i am getting values of PLC tags through CoDeSys OPC
IN Matrikon OPC client OPC quality – Good , non specific.

CoDeSys OPC and SCADA Comm both are running in same user account

for reference image see in below link.

Hi,

Communicator consists of the 2 apps:
1. Graphical shell (ScadaCommCtrl.exe)
2. Windows service (ScadaCommSvc.exe)

Your screenshot shows that the graphical shell works as Arvindh user. You should switch to Details tab of the task manager and check ScadaCommSvc.exe

Thanks Mikhail,

ScadaCommSvc.exe ran in different USER
Then i changed to same user of CodeSys OPC .
after Change it and Restarting the System , PLC tags values recived correctly in SCADA COMM and OPC Quality Status : Good

Thanks.

Hello, I have same problem but changing user doesnt help me, do you have any advices?

[Mikhail]

Hi,
Please try this advice.
Does ScadaCommMono.exe work with the OPC?

[Seakz]

Hi, Mikhail, I already solved my problem but in really strange way: I am using codesysOPC so when I work in siglePLC it shows me badconnection, but in multyplc mode it works 🙂
Anyway thanks for response

[Mikhail]

Interesting.
Are “siglePLC” and “multyplc” set by a parameter of the OPC server?
