If it works in LabVIEW 2016, but not in LabVIEW 2017, I have two (three?) suggestions:

• Use LabVIEW 2016.
• Wait until LabVIEW 2017 SP1 is released, then try that.
• Wait until LabVIEW 2018 is released, then try that.

I'm really hopeful that you will not need to use the third solution.

Is LabVIEW 2016 allowed through the firewall and LabVIEW 2017 blocked?

Hi,

1. You can use the Forward Browse.vi to get the information of the node. In the browse result, what is the node type?

2. What is the OPC UA server? Is it a 3rd-party server?

Thanks!

1-all things is ok except write data
2-yes server is twincat opc server but in labview 2016 and uaexpert opc client all things is ok

Hi,

You can use the Forward Browse.vi to know what is the node type of the assigned node as follow.

 The status "Bad_WriteNotSupported" is often caused by the node type is unsupported. So we'd like to know the node type.

Thanks!

Hi,

What is the OPC UA server?

Is it possible to reproduce this phenomenon on my side?

Thanks!

HI, I have the same problem... LabVIEW 2016 can write the tag, while 2017 cannot, with the same BadWriteNotSupported error.

The firewall is disabled, and the result of the Forward Browse for the given tag is:

reference type: Organizes

node ID: ns=2;s=iTestAliases.Pippo

browse name: Pippo

node class: variable

node type: DataItemType

Thank you for helping!
