Chapter 5 Manually Configure the DeviceNet Network
In this example, four output devices are mapped into the scanner’s output
image. The dialog box shows each device’s:
• node number.
• catalog number.
• connection type used between the scanner module and the slave device
(strobed, polled, cyclic, or change of state).
• amount of data that will be exchanged (in bytes).
• word within the controller’s output image.
Auto Device Replacement (ADR) Tab
The Auto Device Replacement feature automates the replacement of a failed
slave device on a DeviceNet network by returning it to the prior level of
operation. This includes Configuration Recovery (CR) and Auto-address
Recovery (AAR).
CR allows a slave device to be removed from the network and replaced with an
identical slave device configured at the same communication rate and node
address as the device being replaced.
