Examples of Function Block I/O Node References
The first example represents output node 2 of an ADD function block
that has a block ID of 6. You can convert this information to either a
decimal value or a hexadecimal value.

The second example represents output node 3 of an XOR2 function
block that has a block ID of 26.

The third example represents output node 16 of the BIN2DEC
function block that has a block ID of 14. Notice that the first number
in hex for this example is 9. Normally, you can recognize a function
block by an initial hex number of 8, unless the seventeenth I/O node
(node number 16) is being referenced.
