 <h2>OPC UA IIoT Write</h2> <p>
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.
</p> <p>It needs a <pre>msg.valuesToWrite</pre>
 to write values and datatypeName in the addressSpaceItems objects is required.</p> <p>
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]!
</p> <p>
It is important to have the injectType write in the msg object! That is to protect your flow in event based flows.</p> 
<h3>Input</h3> <ul> <li>payload (value to write one or all)</li> <li>topic</li> <li>
addressSpaceItems or nodesToWrite (Array of Node-Ids) </li><li>nodetype (inject)</li> <li>injectType (write) </li><li>
valuesToWrite (Array of values or objects to write individual)</li> </ul> <h3>Output</h3> <p>Results in message:</p> 
<ul> <li>payload</li> <ul> <li>statusCodes (Array of Status Codes) </li><li>nodesToWrite (Array of Node-Id)</li> </ul> 
<li>topic </li><li>nodetype (write)</li> <li>resultsConverted (Array) </li></ul> <p>
Set showErrors to get errors from node-opcua on browse.</p> </script>
