Stored value
In the data types UBIN32(D), BIN32(L), BCD8(EB), and Float32(F), two words (upper word and lower
word) are used for a single value. The MICRO/I and external devices communicate data in device
addresses in one word units, so when the upper word and lower word are sent in separate packets, the
value may have already changed when the data for both words is received, which may cause an
unexpected result.
