====OPC-UA====

The OPC-UA output module turns your system into an OPC-UA server that can be read from a variety of industrial systems and protocol converters, allowing you to feed values from your analytics back into your industrial historian, SCADA system or even inject it into your PLCs.

This is a //service// module - meaning that rather than //writing// data to another system, it opens a server to make that data available to systems that might want to read the information.

^Parameter^Default^Meaning^
|**port**||The port number to host the OPC-UA server on.|
|**ip**|0.0.0.0|The IP address to run the server on|
|**namespace**|<nowiki>http://examples.freeopcua.github.io</nowiki>|The name of the OPC-UA namespace|

===Example===

<code>
[
   {
       "method": "opcua",
       "port": 703
   }
]
</code>

//The above example would make your data available via OPC-UA on port 703//
