A-3.7 Sweep Impact of Intelligent Option Modules
The tables in this section list the sweep impact times in microseconds (µs) for intelligent option modules.
The fixed sweep impact is the sum of the polling sweep impact and the I/O scan impact. The opening of
the Backplane Communications Window and the polling of each module have relatively small impacts
compared to the sweep impact of CPU memory read or write requests.
Intelligent option modules include GBCs being used for Genius LAN capabilities. The sweep impact for
these intelligent option modules is highly variable.
