accessed using the variable Inspector within Machine Edition. The Machine Edition variable
Inspector is displayed in the screenshot below for reference.
The available PME Publish attribute selections are as follows as they apply to the OPC UA
server:

The RXi's OPC UA address space supports 12,500 addressable elements. If
Note:
more than 12,500 addressable elements are published, only the first 12,500
(listed alphabetically) will be made available in the OPC UA address space.
Each index of a variable array counts as a unique, addressable element.
