The logic multiplies (MUL function block 6) the high word by 65536 (Source
B) and adds it to the Low Word (Add Function Block 7). Function blocks 3, 4,
and 5 change the signed word value into an unsigned double word value.
Function block 3 checks if the low word is less than 0, if so, the Select block
will output 65535 to the Add block. Otherwise, zero is added to the low word.
