3-4 Operations

DeviceNet Operations

The Allen-Bradley 1747-SDN and 1771-SDN DeviceNet Scanner

Modules are master devices on the DeviceNet network. The

RediSTATION supports the Master/Slave Connection Set for master/

slave communications on the DeviceNet network.

To communicate with a RediSTATION, the DeviceNet Scanner Module

must be configured with the RediSTATION:

• node address

• input bytes (1)

• output bytes (1)

The DeviceNet Scanner Module:

• connects to the RediSTATION slave device

• performs the appropriate connection configuration

• polls the RediSTATION for inputs and outputs

Response Times

The RediSTATION responds to a DeviceNet Scanner poll within 1

millisecond.

The switch inputs are debounced for 50 milliseconds. When a change

of state is detected, the inputs are not read for another 50 milliseconds
