OPCDA Configuration in KepserverEx

[AT_10497233]

I am trying to connect to a remote OPCDA Server using Kepserverex. But when i try to import tags i can browse the tags but there will be an error coming."Failed to establish callback for device. Even if after that i import the tags the tag quality will be bad and tag value will not update. In the same system i am accesing the remote opcda server using other opcda client but it is working. Can anybody Help?
