52 DNI Configuration Parameters and Programming Notes
Example
With the starting output word at N7:95 (Output Word Offset), and the
starting input word at N7:90 (Input Word Offset), you need to
program this rung in the controller’s program to move the heartbeat
bit.
Your program should also monitor N7:95/7 for activity. If activity is
lost, it represents a problem with the connection to the DNI, or the
DNI has some type of error or problem.
See the application example MicroLogix as I/O on the DeviceNet
Network on page 69 for more information about using the DF1
Heartbeat.
