Is there anyone out there who has had experience configuring an Emerson CSI 6500 Vibration Monitor to talk to a ControlLogix PLC via Modbus TCP?

I have a ProSoft MVI56E-MNET card in my ControlLogix Chassis. The card has been tested with a separate device which has a predictable output. So I know it is configured correctly.

When I poll the vibration monitor, I observe data in the PLC registers, however, it is nonsense (i.e. not at all what is expected given the instruments it is attached to).

Any help is appreciated.

 

Is it possible the data is coming in with byte order swapped?

Or the data is in floating point format?
