Monitoring Node Health (Performance)

Monitoring node health is important to do in a wireless network to ensure that all radios are communicating and providing up-to-date data. This example will cover using a DXM to monitor node health and send an output when a node drops communication.

The health register for performance nodes is always I/O 8 (register 24 for node 1, register 40 for node 2, register 56 for node 3, etc.). The value of this register will be “128” when the node is in normal operation. When the value is NOT 128, then this usually indicates some type of error. The most common error code to appear here is “13569” which indicates a link loss. However, it is usually best (and easiest) to monitor this input and fire an output whenever the value is NOT “128”.
