    Chapter 12 Redundant Systems ControlNet Considerations You can have as many as seven ControlNet communication modules in a redundant chassis. in Redundant Systems With each ControlNet network, you must have at least two nodes external IMPORTANT to the redundant controller chassis to avoid timeouts on switchover. The lowest node of each ControlNet network must be outside the redundant controller chassis.

  • Page 181: Redundancy And Scan Time

    Redundant Systems Chapter 12 Redundancy and Scan Time At the end of each program, the primary controller synchronizes and crossloads fresh data to the secondary controller. This process keeps the secondary controller up-to-date and ready to take over. It also increases the scan time when compared to a nonredundant system.
