Hello Every Body,

I am trying to realize a communication between PC station with Simatic OPC V15 server installed on Virtual Machine (Windows Server 2012 R2) ,and a PLC runs a program under Simatic Step 7 V5.5.

I created a Project under TIA portail V15 and I added PC station With OPC server V15 and dummy  PLC(just to import the variables in it , i did give the same ip address of the PLC  ) .

I imported all variables and DBs from S7 project through the external source approach(export an external source from project S75.5 then imported on TIA V15 )

I can see all the variables and monitor them through TIA V15.

I export the project on XDB file and transfer it to the virtual machine and i did an import station procedure .

The problem is that when i open OPC client Scout 10 or matrikon i can brose the variables but i had bad quality and i can not read the values through the opc client , it says that the qualty is bad and then an E_FAIL 

Can you tell me why i had a bad quality and i can not communicate with PLC?

Hello WISSAM1985

Can you see the current value of the Tags? Or do you see only Bad quality an no connection to the PLC Tags...?
