I am getting a new machine which is controlled by FANUC PLC.  
The supplier has also said that the can setup OPC-UA communication so that we can get data from the machine.

I have never used OPC-UA before, but from looking at the nodes, all I need is the IP address, Port number and the data list (Tags so i can collect the information I need)?  
Is there something particular about the FANUC PLC's or do they work fine with the node-red-contrib-opcua.

This company is not aware of node-red as they were confused when i stated that i planned to use Nod-red OPC-UA to capture data from their machine.

Any help is really apprechiated

If it is OPC-UA and not locked down by Fanuc, there is no reason OPC-UA in Node-RED will not work. In other words, give it a go.

Note, that node has several built-in example flows (accessible via `CTRL-I` -\> Examples)

If you're not fixed on using OPC-UA and just want to read data from the PLC, you could also try using the Focas interface, if available.

We use the project linked below to read data from Fanuc series 32i and 18i PLCs.  
Data is polled at a configurable interval and can be published to a number of targets, including MQTT.

In our use case, we have about 25 devices and it works like a charm.
