Zero code development: How to complete device access in 5 minutes

introduction

In traditional industrial IoT projects, device access often requires professional software developers to spend days or even weeks on protocol parsing, data mapping, interface development, and other tasks. This not only increases project costs, but also prolongs the implementation cycle.ModbusThe zero code development feature launched by the IoT cloud platform has completely changed this situation. This article will provide a detailed introduction on how to complete device access in 5 minutes using zero code method.
