The ControlLogix system contains a 1756-DNB (node 00). The 1769-SM1 is a component in a 1769-ADN DeviceNet adapter
drop (node 2) along with a 1769-PA4 power supply and 1769-ECR End Cap Terminator. The 1769-SM1 has a PowerFlex 70
connected to each of the three channels.
This rung commands the 1756-DNB to run.
