12 Quick Start

5. To exchange data with other controllers over a DeviceNet

network, configure a message instruction inside each controller’s
program.

See Programming Over the DeviceNet Network on page 21 for
more information.

6. To send data to a specific controller on the network, enter the

destination DNI’s DeviceNet node address into the destination
parameter of a message instruction. Think of each
DNI/Controller pair as one unit.

IMPORTANT

If your network consists entirely of DNIs (no master is present),
you must disable Autobaud on at least one DNI. It is
recommended that all DNIs be manually set to a specific baud
rate. This is to prevent multiple DNIs from hunting for a baud
rate at power-up.

EXAMPLE

To send a message from controller A (plugged into DNI number
5) to controller B (plugged into DNI number 10), controller A
must have a message instruction with a destination node
address of 10.

See the application example MicroLogix as I/O on the
DeviceNet Network on page 69 f
or an example ladder program.
