Hello.

Can you now help me too? Because normally this should not be necessary, and I'd like to get to the bottom of it. I'd like to know

1) Which of the types has worked in the end (Int16, Int32, Int64)?
2) You mentioned "omron", but can you be more specific as to which model/version etc.?
3) I assume this is an OPC UA server that is embedded inside some PLC, and not a PC-based OPC UA server. Is that correct?
4) Would you be willing to extract more information about the server, by downloading the current version of the OpcCmd utility from kb.opclabs.com/Tool_Downloads#OpcCmd_Utility , and then, from inside that utility (at the OpcCmd> prompt), enter the following command:

uaClient read //172.16.253.6:4840 --NodeStandardName Server_ServerStatus_BuildInfo
and post here the screenshot?

Thank you

Can you modify your code according to opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...d%20specify%20data%20type.html , and in the last argument to WriteValue, vary

- typeof(Int16)
- typeof(Int32)
- typeof(Int64)

Thank you

Thank you, this is what I wanted, now one more question: What is the actual value that you are trying to write, in your test?
