Map ModbusTCP data to assets

Question

I have set up a Modbus TCP source on a gateway.  I can see that it is successfully polling data by looking at ModbusTCPConnector.log on the edge device.  But I can't figure out how to map the Modbus tags to asset measurements.  I have tried various aliases on the measurement (such as source/channel/tag) to no avail.  How is this done?  
  
Thanks,  
Tim

Answer

I figured this out.  The Tag under the Property Group is the alias for the asset measurement.  There is no hierarchy.    
  
I had tried this earlier but it didn't work due to a security issue.  There is a periodic log entry in swPublisher.log.    
  
_\[2021-03-31T21:57:14.687-05:00]\[INFO]-2021-03-31 21:57:14  INFO  BufferedMetricsPublisher:90 - Emitting diagnostic name=PublishError.AccessDeniedException, value=6, timestamp=2021-04-01T02:57:14.658Z, dimen....._  
  
Apparently if "value" in the log entry is not zero then there is an AccessDeniedException somewhere.
