Abstract

This article presents the design and development of an electronic module based on the ESP32 microcontroller for the purpose of unifying and interconnecting various industrial networks. The architecture integrates protocols widely used in today's industry, such as Modbus RTU using the ADM485 transceiver, Modbus TCP/IP through the ENC28J60 Ethernet controller, CAN Bus communication using the MCP2551 transceiver, and DeviceNet networks using a combination of the MCP2515 and MCP2551, using the ESP32 microcontroller. It also incorporates compatibility with Profibus networks using the MAX14770 transceiver, as well as integration of smart instrumentation using the HART protocol employing the AD5700 modem and serial protocols such as RS232 and RS485.The electronic module enables bidirectional communication between industrial equipment using the most commonly used communication protocols in the industry today, facilitating the modernization of industrial equipment such as frequency converters, PLCs, or input and output expansion modules in existing systems without the need to completely replace this equipment. The module contributes to unification by selecting the appropriate network for a device or equipment and to the digitization of processes in Industry 4.0, achieving improvements such as interoperability, robust connectivity, and integration into multiple equipment without the need to make changes to their hardware. The electronic module adapts to an industrial environment and integrates 75% compatibility between devices such as PLCs, frequency converters, and I/O expansion modules.
