1. Before installing a 1756-CNB module in its chassis, set the module's
node address switches.
Important: You must select a unique node address of 01 to 99 for each
module. 00 is invalid.
For the example applications, set the node address of one 1756-CNB
module to 1 and another to 6. In the last example (chapter 11), we added
a third module at node address 3.
