System Mode Control
When you first time start a new copy of Neuron, it immediately undergoes the registration process by sending the registration request to the IIoT platform repeatedly until it gets back the response. If registration pass, Neuron would enter Inactive mode running without any configuration inside. At this moment, users can setup the configuration such as data registers, alarms and event. After setup finished, Neuron need to restart to enter the Active mode.
API service functions are mode dependent. That means some functions are restricted to be called in specific mode. Moreover, heartbeat and telemetry transmission are also mode dependent. Data polling would perform in active mode only. Below there is table shows the availability of various API services and transmission in different mode.
