The modified Inject node is designed to provide some unique features you need to create beautiful flows.</p> <p>
Pressing the button on the left side of the node builds an inject object to read, browse, listen or write by the OPC UA IIoT nodes.
</p> <h2>Configuration</h2> <h3>Tab Settings</h3> <strong>Type</strong> <p>
Set that type to prepare the correct value for injects.</p> <strong>Payload/Interval</strong> <p>
There is an option to send a JSON payload inject into the Listener.</p> <p>Example:</p> <p><pre>
{ "interval": 500, "queueSize": 10 }</pre></p> <div> <h5>msg.payload.options<h5> <strong>
event subscription parameters default: <pre>
        msg.payload.options = {
            requestedPublishingInterval: 100,
            requestedLifetimeCount: 60,
            requestedMaxKeepAliveCount: 10,
            maxNotificationsPerPublish: 4,
            publishingEnabled: true,
            priority: 3
        }
        </pre> <strong>subscription parameters default: <pre>
        msg.payload.options = {
            requestedPublishingInterval: 100,
            requestedLifetimeCount: 1000,
            requestedMaxKeepAliveCount: 12,
            maxNotificationsPerPublish: 100,
            publishingEnabled: true,
            priority: 6
        }
        </pre> </strong></strong></h5></h5></div> <p>
If the Inject-Type is set to read/write, then the value is a standard payload to transport your data.</p> <strong>Topic
</strong> <p>The topic is to group for queues or protocols like MQTT.</p> <strong>Repeat</strong> <p>
With the repeat settings you can set a cron configuration.</p> <p>
The interval settings needs a short delay on start. This is equal to the once option but without any inject at to start working.
</p> <strong>Inject once at start</strong> <p>
The 'Delay sec. at start' has to be set to a minimum for starting injects toward the OPC UA server.</p> <p>
All activities will start ever <strong>after</strong> the start inject is done.</p> <p>
I did a contribute to Node-RED to provide that delay at start from Node-RED 0.18 inject too.</p> <strong>Name</strong> 
<p>Name in the flow of Node-RED.</p> <h3>Tab OPC UA Items</h3> <strong>Name (optional)</strong> <p>
A short human readable name for long or numeric nodeId's.</p> <strong>Node-Id (mandatory)</strong> <p>
The Node-Id has to be an OPC UA valid Node-Id like ns=0;i=85 (root->Objects)</p> <p>
You can use our Browser node for OPC UA to find the correct Node-Id.</p> <strong>Data Type (mandatory/optional)</strong>
 <p>The Data Type setting is needed to do the converts of the node-opcua Variant type result(s).</p> <p>
It is mandatory to write data otherwise it is optional!</p> <p>
In best practice do transformations with the Result Filter node.</p> <div> <strong>Content of an inject:</strong> <ul>
