 <h2>OPC UA IIoT Flex Connector</h2> <p>
 The Flex Connector node is to set up an event listener with parameters to change the linked connector settings and restart the connection. It is to trigger by an Inject of Node-RED or by the IIoT OPC UA Inject. It could also get a trigger with incoming events from other nodes. 
</p> <h3>Input</h3> <p>
The node takes the parameters from the msg object or from the node setting as default. That means - an empty msg object will just reset the connection and is like a command to just restart the connector with the node parameters.
