Hi folks, I am a little new to Node Red but have been getting up to speed.  
I have an application I have test on my Windows 10 Laptop using a KepWare Server and the iiot OPCua Pallet. I loaded the newest version of Node JS and the latest version of Node Red.  
I can build the flow and it works fine on my laptop. I can read values for an OPC ua server.

The machine I am testing with is a Windows 7 desktop PC. I installated of Node JS and Node Red goes OK and installs properly. Then I install the iiot OPC ua Pallets.

> npm install node-red-contrib-iiot-opcua

That installs fine. Once I import the flow the Injector Node loses it Properties.  
I then place a new iiot OPCua Injector in the flow and it shows up Blank?

I then Uninstalled Node-Red and deleted the .Node-Red directory.  
I reloaded Node Red and tried to install an older version of the iiot OPCua pallets using

> npm install node-red-contrib-iiot-opcua@2.7.1

I am still missing the properties for the injector node and there is no text on the node like the other iiot OPCua node I can drop in the flow?

Not sure what I an doing incorrectly?

Thanks,

As per the docs, the recommended version of nodejs is the LTS version. Which is also the version that the nodes readme says it is tested against. I would suggest trying with that and if you still have an problem, open an issue on the nodes github page.

I use the iiot-opcua with node V10 LTS & it works ok. Never tried with V12. Try rolling back nodejs to v10.

You haven’t ever said what version of Node-RED you are using.

The readme says it is tested against v0.20.x

What version of node red? Look in the start up console messages or the menu of node-red (top right hand hamburger menu)
