I am trying to communicate Yudian AI-526 controller with labview. It has RS485 and communicates on AIBUS protocol and gives data in its own yudian OPC server. We just have to config the controller model in that opc server and when we connect RS485 to USB converter to pc and open the yudian OPC server it gives data in OPC server. So i am trying to take data from yudian opc server into the labview. I have used OPC client in the project and selected the yudian opc server. It also shows all the tags of my yudian opc server but i am not able to get values it shows all values "0". Has anyone communicated with yudian OPC server and labview please help.
