DeviceNet 5-3

I/O Message Types

The BridgeWay supports all I/O messaging types specified by the DeviceNet pro-

tocol. These include strobe, poll, COS, COS Unacknowledged, Cyclic, and Cyclic

Unacknowledged I/O messages. I/O messaging and I/O parameters are configured

using the DeviceNet configuration tool.

I/O Mapping

The contents and layout of the data in the I/O tables is defined during configura-

tion of the scan list. The input and output data of each slave is configured, or

mapped, to specific locations in the input and output tables.

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.
