Rockwell Automation RECOMM-IBUS Interbus Communications Module - Manual (Page 39)

Configuring the Interbus Scanner 5-9
Step 13. Right-click on the SST-IBS-SLC scanner and select
Process Data. This shows the Interbus I/O mapping for
each device on the network, as shown in figure 5.12.
In the example, the length is 144 bits (9 words) because the
RECOMM-IBUS was previously configured for the maximum I/O
configuration. (See section 4.3, Setting the I/O Configuration.
Depending on your application needs, this length may be less.)
The scanner mapping correlates to SLC addressing as shown in
figure 5.13.
