Writing to Datalayer over OPC UA in Node-Red

[Sgilk]

Writing to the datalayer via the OPC UA server using a Node-Red based OPC UA client causes the Node-Red application to crash. Reading is working fine using the same endpoint. I am testing this on a ctrlX Core Virtual.

Hello

we can reproduce the problem. Seems a problem of the UA-Node itself. Please report the bug to

node-red-contrib-opcua (node) - Node-RED (nodered.org)

mikakaraila/node-red-contrib-opcua: A Node-RED node to communicate OPC UA. Uses node-opcua library. ...

Hello Sgilk,

You have to put the Datatype back in the node injection, or use the OPCUA Item. I have tried it with an Int16 and a Boolean and it works.

Pleae have a look to the examples in the documentation of the node-red-contrib-ctrlx-automation nodes. There you can see how to handle different data types.
