This is a pretty impressive suite of tools for providing diagnostic information on an HMI. Unfortunately that's all its for. There is no symbol information in the block. If I want to determine if a station is active in the PLC program it looks like I'll have to use the HMI tags and reverse-engineer a way to do it. Not saying it can't be done, but... All I want to know is if an inverter is actively communicating.

If someone has figured out how to do that I would appreciate sample code. It would save me a lot of time.

Thanks,
