Int, U_Int: Read / Write a 2-byte data location
Other formats:
Long, U_Long: Supported, but data is truncated to 2-bytes
Float : Supported. but data is converted from a 2-byte integer.
Mask usage:
Other than discrete point types, which return a single bit value 0 or 1, other point type
may also use the mask setting. In its simplest use, the mask can be used to limit data
written to the memory location. (Mask = 0x00FF will limit data to the range 0…255)
The mask may also be used to isolate bits in a word, so that other data within the
word is not corrupted.(Mask = 0x00C0 will only read / write bits 7 and 6)
