Trying to get Client to read Modbus Float Correctly

Ignition

I am having trouble reading the true values from the PLC. The PLC shows the correct value but getting it to show up correctly in Ignition/vision is not working.

I did try both HRBCD and HRF. Modbus address is correct, its -1. D290 =400291-1 =400290
I'm sure its something simple I'm missing.

Use HRF, not any BCD format. You probably need to play with the driver's word order swapping option. Possibly also the setting for zero-based versus one-based addressing.

Changing the 'Reverse Word Order' to true and setting both to HRF did work.
Not sure what I messed up the first time.
