By storing slave contact input data into internal relays as shown below, we can then use
the internal relays as substitutes for the slave contact input relays.
The following program stores slave contact input data into internal relays of the ASi
Master module installed in slot 4.

After execution of the READ instruction, we can use internal relays I00005 - I00256 as
substitutes for the slave contact input relays. (Although the first device is specified as
I00001, positions I00001-I00004 and I00129-I00132 contain invalid bits since they map
to no slaves.)
