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.
