Rockwell Automation 20-COMM-I Interbus Adapter - Manual (Page 26)

3-4 Configuring the Adapter
4. Interbus requires the network I/O mapping to be configured first in
the adapter. CMD software will read this configuration online when
it is configuring the scanner.
Process Input Data Description (PIDD) words map input data on the
network (data seen as inputs to the scanner and controller program).
Example input data includes Logic Status, Feedback and Datalinks
(Datalink x1 Out). Up to 9 words of input data can be mapped.
Process Output Data Description (PODD) words map output data on
the network (data sent as outputs from the scanner and controller
program). Example output data includes Logic Command, Reference
and Datalinks (Datalink x1 In). Up to 9 words of output data can be
mapped.
The following indexes are used to select the I/O data:
