Page 9: Controlnet Overview
Chapter ControlNet Overview The ControlNet network provides high-speed transmission of time-critical I/O and interlocking data and messaging data. This data transfer capability enhances I/O performance and peer-to-peer communication in any system or application. The ControlNet network is highly deterministic and repeatable and remains unaffected as devices are connected or disconnected from it. - Page 10 Chapter 1 ControlNet Overview Figure 1 - ControlNet Modules and the Control System Overview Item Description Personal computer running SoftLogix5800 controller with 1784-PCICS card 1756-CNB module (as an adapter) with 1756 I/O modules PowerFlex 700S drive 1794-ACN15 adapter with 1794 I/O modules 1734-ACNR adapter with 1734 I/O modules PanelView terminal CompactLogix 1769-L35CR controller with local 1769 I/O modules...

Page 11: Bridge Across Networks
ControlNet Overview Chapter 1 Bridge Across Networks Some ControlNet modules support the ability to bridge or route communication to and from different networks, depending on the capabilities of the platform and communication devices. You can only bridge across networks to communicate with devices. You IMPORTANT cannot bridge across networks to control I/O, even though RSLogix 5000 software can accept such a configuration in the I/O Configuration folder. - Page 12 Chapter 1 ControlNet Overview Figure 2 - Drive Configuration on a DeviceNet Network P WR S TS PORT Item Description Item Description Workstation Drive PanelView terminal DeviceNet network Bridge ControlNet network The performance of a CompactLogix controller on a ControlNet network IMPORTANT degrades significantly if you use the controller as a bridge.

Page 16: Network Update Time (Nut)
Chapter 1 ControlNet Overview Network Update Time (NUT) The network update time (NUT) is the shortest interval in which data can be sent on a ControlNet network. It represents the fastest possible update rate for scheduled data transfers on that network. For example, a network that runs with a five ms NUT cannot send scheduled data at a rate faster than five ms. -
Page 17: Requested Packet Interval (Rpi)
ControlNet Overview Chapter 1 Requested Packet Interval (RPI) The RPI is the update rate specified for a particular piece of data on the network. By using a rack-optimized connection, the RPI can specify the rate for an entire rack of I/O. With a direct connection, the RPI can specify the rate for a particular module or peer-to-peer data. -

As long as at least one valid multi-keeper device is present on the network, new scheduled connections can be established. To review the valid keeper devices on your network, follow this procedure in RSNetWorx for ControlNet software.
