For my next trick with Ignition, I’d like to write a proper OPC UA driver for a device that communicates via OPC XML. Since I’ve never done this before, I looked over and build the Abstract Tag Driver Example and Weather Component example that came with the SDK. Both modules installed alright, however, when I went to add a device of the ATDExample variety, there was no option for that device in the list.
The weather component popped up under Inductive Automation -> weather. If I’m understanding the sample code correctly, the ATDExample type should appear under Examples -> ATDExample. Neither the Examples folder, nor the ATDExample item appeared.
The DriverMeta -type classes looked almost identical. Why does one work and the other not?
