DeviceData is a frozen container slot under most LonDevice objects. It contains the data needed to represent a specific neuron chip including state information and configurable data in the neuron tables as described in “Appendix A: Neuron Chip Data Structures” in the Neuron Chip Data Book.

In the case of a LonRouter, two DeviceData container slots exist: “Near Device Data” and “Far Device Data”, representing both of the router’s neuron chips (relative to the LocalLonDevice).
