Designing C Library for MODBUS-RTU to CANBUS and MODBUS-TCP IOT Converters

The IoT converters have made the communication between different devices working on different protocols very easy and convenient. This paper deals with designing a C library for two IOT Converters in which one device is working on MODBUS RTU to CANBUS protocol conversion and the other is working on MODBUS RTU TO MODBUS TCP/IP conversion, also implementing the same on the hardware. Creating a C library for establishing such communication involves socket programming which deals with setting up both wired and wireless communication. This paper covers the basic understanding of various serial communication protocols, their working and implementing the same at the hardware level. Here, this research work has laid down the flow of the converter diagram and also mentioned the algorithm for creating a C library. Working on the Modbus and Can protocols has proven beneficial given the capability of Modbus to support multiple devices on the same cable and the capability of CAN to replace the complex wiring system used in automobiles with an easy two-wire centralized bus system. In the end, this research work has discussed the application of these types of converters in real life and also compared them with any general IOT converter.
