What Is DriveLogix? 2-19
This example system has these details:
• I/O modules on the local rail are digital, so configure each module for a
rack-optimized connection
• I/O modules on the extended-local rail are analog, so configure each
module for a direct connection
• I/O modules on the ControlNet network are 4 digital and 4 analog, so
configure each digital module for a rack-optimized connection and each
analog module for a direct connection
• there are no produced or consumed tags
• the controller sends 2 messages to other devices on the ControlNet
network
• the controller uses 2 connections to the 1788-DNBO module to collect
data from the DeviceNet devices
