When switch1 is true, the instruction reads one
word of data from register 300 of the I/O
module in slot 4 of the AutoMax rack. This data
is placed in the variable pump.
If you were to use an address instead of a slot
and register location, the example would look
like the instruction below. The Address of
240258H is derived by this formula:
base register address of slot 4 + 2
the register number
Consequently,
240000H + 2(300)=240258H.
