P1000 word swap on float 32 bit Modbus register? How?

I have a P1000-550 that is reading a modbus register Float 32 bit as CDAB (low word, high byte) from a slave device. I need to convert the tag name (modbus address) to ABCD (high word, high byte) so it readable by another device on the system. Is it possible to word swap the data to a new tag name or some other method?

    If you are using a MRX instruction to get the data, there is a checkbox for Word Swap on that instruction about halfway down on the left. That would cause word swap to be applied to all of the 32 bit values being read by that message instruction.
