I am trying to find information on talking modbus to ABB ACH550 drives with integrated Eclipse bypass controls. I have two air handlers that each have 2 of these drives in them. I am using a stride modbus rtu to tcp gateway.
 
I have comms working, however, i dont know what the eclipse registers are. Does anyone have a manual for the eclipse registers?
