WinCC RT Adv can't read OPC UA tags. There is message "Connection to PLC is interrupted" (pic 1). Although, I can browse variables in the Address column (HMI Tags tables), so connection is established. I have tried to connect used Prosys UA Client and OPC expert (pic 2,3), both of them are successful. I don't have encryption and password. Any ideas? Attachment all_pic.png (120 Downloads)
