When configured with a Hand–held Monitor, the Remote I/O Scanner automatically
assigns I/O references to the modules in the remote drop starting with the reference(s)
assigned by the user via the Program Block ID screens. The left–most module of each
type (%I, %Q, %AI, or %AQ) in the rack receives the first available reference of the
appropriate type. The HHM then incrementally assigns references according to the
types and locations of modules in the rack, in left–to–right order.
Example
For this remote drop, %I, %Q, %AI, and %AQ references each begin at 0001. There is
no requirement that they all start at the same value.
Left reference values increase Right
