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
