[00:00] The Micro800 driver supports OPC-UA server browsing for global scoped variables. However, there are a few exceptions of global scoped variables that cannot be browsed. These include UDTs booleans and non indexed arrays. These will need to be manually added in order to be used in ignition. They could be added through individual addressing. However, we recommend creating a tag import file, which can be generated from the connected components workbench. I'm here in the connected components workbench application, used to program my my Micro800 PLC. While in your Micro800 project, you'll want to navigate to the project organizer pane and right click on the desired controller. Then you would highlight export on the pop-up menu and choose the variables option. Finally, you would choose a download location and save the file as a CSV. Once the CSV file is downloaded, we can navigate to the ignition gateway on the gateway.

[01:05] Go ahead and select the config tab. I'll scroll down here and select device connections under OPC-UA on the connections page, we can use this more option to access addressing or importing or adding non browsable tags. Using the load configuration button, we can import the CSV file gathered from the connected components workbench. I'll click on load to import my file. Now the list of tags that populate here will be filtered to only non browsable tags. This helps to avoid any redundant tags or collisions. If everything is looking good here, go ahead and save the configuration. One thing to keep in mind is that local scope variables, which cannot be accessed, are not filtered out of the import file. For example, if I go to the quick client here and drill down to my 870 device, you'll see a local scope function block variable. Trying to read this variable will result in a null value. For more information on tag addressing and imports, refer to our user manual.

[02:04] I've included a link to that manual below this video.
