How can I read float values over ControlNet?

On the HI 4000 series (which include the HI 4050 and HI 4060) and the HI 3000 series (which includes the HI 3010, HI 3030, HI 3300, and HI 3600), when data is sent as a float value it means the value is in IEEE float data format. These will be 32 bits of data that is then split into two 16 bit words, the MSW (upper 16 bits) will be in the first word location and the LSW (lower 16 bits) will be in the second word location. Once you have these two words in the processor, a copy command from the integer (16 bit) locations into a float (32 bit) location will re-assemble the two parts of the split value into the one float value. The copy command is used to preserve the bit pattern of the IEEE float formatted data. Once the bit pattern is copied into the float location, the PLC will then interpret the value correctly.
