Replied by support on topic reading data from siemens OPC-UA server
Hello,

that would be, for example,
Range("D6").Value = Client.ReadValue("opc.tcp://192.168.72.12:4840", "nsu=http://www.siemens.com/simatic-s7-opcua ;ns=3;s=""dbTraceBack"".""StepResponse""")

Best regards

Note: This appears not to be using Excel Option (the category of the forum post you have chosen) - it is VBA in Excel I suppose, which is a different thing.
The Excel Option allows to achieve the same without coding.

Hello,

i'm testing the functions of the EASYUA-client and do not know how to set the parameters.

Can someone tell me the correct parameters in EASYUA-Client to get the data of a Siemens OPC-UA server.
In den Connectivity Explorer i found the field with this settings:

="opc.tcp://192.168.72.12:4840, BrowsePath=""[ObjectsFolder]/CPU.DataBlocksGlobal/dbTraceBack.StepResponse"""

OPC-UA Node
Node Id:     nsu=http://www.siemens.com/simatic-s7-opcua ;ns=3;s="dbTraceBack"."StepResponse"
Browse Path (*): [ObjectsFolder]/CPU.DataBlocksGlobal/dbTraceBack.StepResponse
Node Class: Variable
Browse Name:    StepResponse
Type Definition:    BaseDataVariableType
Reference Type Id:    HasComponent


What i have to type in the parameter values?

Range("D6").Value = Client.ReadValue("???","???")

Thanks in advance.

Hans-Jürgen
