RX3i I/O Module Sweep Impact Times
The following table provides sweep impact times for modules in the Main rack and in an
expansion (Exp) rack. The base case provides the overhead for a single module in the rack.
The increment (Inc) refers to the overhead for each similar module that is added to the
same rack. To estimate sweep impact for modules in a remote rack, multiply the time in
the main rack by 6:
main rack base time × 6 = approximate sweep impact in remote rack
