DeviceNet 5-4

Proxy for Group 2 Only Devices

The BridgeWay provides the capabilities necessary for being a Group 2 Only Cli-

ent as defined for the Predefined Master/Slave Connection Set. Group 3 explicit

messages destined for a group 2 only device that is configured as a slave to the

BridgeWay will be intercepted and relayed to the slave.

Quick Connect Feature

The BridgeWay supports DeviceNet Quick Connect. Quick Connect is a special,

shortened establishment procedure for connections to slaves. Quick Connect can

be used in applications where the normal delay between when a slave comes

online and the scanner establishes a connection cannot be tolerated. Quick Con-

nect is enabled on a per-slave basis using the RSNetworx Tools->Quick Connect

menu.

Active Node List

The BridgeWay monitors the DeviceNet network and tracks the online/offline

state of all nodes on the network. The current state of each node is kept in the

Active Node List which can be accessed the DeviceNet object instance attribute

13. The CIP bridging utilizes the Active Node List to determine whether a target

node is online. If the target node is not online, the CIP bridging functions will

immediately return an error response to the requesting node. The Active Node

List monitoring and bridging functionality can be disabled by setting DeviceNet

object instance attribute 102 to 1.
