Modbus to Hach SC1000

I'm trying to bring in tags from a Hach SC1000. I have tried [Hach]HRF0 bring it in as a float, but for the value I get "bad" I tried to reverse the words in the driver. The Hach SC1000 is zero based, but I even tried one based. Can anyone help me out?

Do you have any other Modbus software (modscan, modpoll, etc...) that can successfully get data as a reference?

Have you tried unit id 1 instead? i.e. 1.HRF1 instead of HRF1.

Yes I can read data with current SCADA system (DFS HT3) and yes tried all addressing types

In the absence of any definitive documentation I suggest you get a Wireshark capture.
