ACS880 to CompactLogix 5380, Eth I/P, Real values... INT communication.

Seems like a simple function, but I don't know how to accomplish it in Studio 5000...

The communication between the ACS880 Eth I/P module and the PLC is with 16 bit integers. I just hit my first REAL value in the drive that I'd like to display on the HMI. I noticed that the value filled 2 fields (communicating to from the VFD to the PLC), as it says it does in the manual. But one thing I haven't done yet is to change those two 16 bit INTs to a real value to display on the HMI.

See the pic....

Any help?

....and while I'm thinking about it, I'll need to input REAL values into the VFD over the same fieldbus communication. How do I take a REAL input from the HMI and convert it to two 16 bit INTs to send correctly to the drive?

You can use COP <SOURCE> <DESTINATION> <LENGTH>
The source is the first INT tag, the destination is the Real tag and the lenght will be 1

Real to INT use the same COP instruction but:
Source is the real tag, destination is the first Int tag, the lenght will be 2.
