In SFC's what are parameter IOID means?

If I recall correctly, it must always be the value b#16#54 for the Siwarex U modules (that's how I have set it up in my code).

IOID is the identity of the address area.

B#16#54 = Peripheral input (PI)
B#16#55 = Peripheral output (PQ)

If you put your pointer over SFC59 and press F1, the Step7 help will be shown and gives the above information (and more).
