Unable to read tag from Powerflex525 VFD #47

Closed nisargpandyadattus closed 6 years ago

nisargpandyadattus commented 6 years ago

I am trying to get Powerflex525X VFD working with CPPPO. It's working with requesting with "@0x0093/3/9" format for getting tag values but when I'm requesting with Tag name "Output_Current" mentioned in document, it's returning with None as response. Also If you can spread some light on how to communicate with Powerflex with Get_Attribute_Single/All from CPPPO library.

You'll need to obtain the documentation for the Powerflex 525X, and compare the details of its internal CIP Class/Instance/Attributes against what is in cpppo/server/enip/ab.py . It is likely that it provides different data at different addresses and CIP data types.
