OPCUA-IIoT-Write

OPC UA IIoT Write

The Write node is for sending data to the OPC UA server. It handles a single data request and multiple data requests. All write requests will produce an array of StatusCodes for writing in amount as applied for and responded.

It needs a

msg.valuesToWrite

to write values and datatypeName in the addressSpaceItems objects is required.

Every entry in the addressSpaceItems corresponding to each array place in msg.valuesToWrite. That means addressSpaceItem[0] will write the data from msg.valuesToWrite[0]!

It is important to have the injectType write in the msg object! That is to protect your flow in event based flows.
