Polled I/O Data Map, Inverter Outputs – The polled I/O for the inverter maps to four
words (16 bits each) input data, and four words output data. This represents a small
portion of the inverter's parameters and commands—just those required to manage
motor operation in real time. Some data words contain discrete (individual) bits (used as
flags), while others words contain values (used as scalar numbers). When the network is
active, polled I/O data is automatically updated on each network scan.

The I/O image above corresponds to the default (Host) Input Instance P_47 = 101. The
Inverter Consumed Data, (Host) Output Instance I/O image is presented in Step 7.
NOTE: P_47 = 70 and P_47 = 71 settings provide other produced data configurations
(not used in this example). See "Polled I/O Configurations" on page 66.
