2–4 Configuring the Module
Configuring the module
As you configure your module, you should complete the I/O image
table. First, size the I/O using switch SW3. Next, set the rack address
using switch SW1. Finally, select the starting group, last rack setting,
fault action, and baud rate using switch SW2. For more information
on the I/O image table, refer to the example below and Chapter 4.
I/O Image Table
Example I/O Image Table
In this example, we use the factory-default settings. We use rack 2,
and record it as our address. Because we are using a full rack, we use
starting group 0, so block transfer starts at word 0.
