Introduction

This document will introduce a NodeRed sample code for user define their own alarm flow and message in iEdge. In this example, we use Modbus-Master plugin to collect sensor data, and if the status sensor returns 0 which means device does not any abnormal, other wise, sensor returns error code. We use NodeRed to design a work flow that will send corresponding error message which depends on the error code.
