WebModbus typically uses RS-485 for it’s RTU implementation. This lib implements RTU half-duplex mode. To use RTU with an ESP32 you need to have an UART to RS-485 converter. The library provides a function to toggle the direction pin (/RE - DE) in case your adapter doesn’t have auto-direction control. A word of caution when implementing RS-485.

WebThere are 4 modbus slave devices connected to the ESP32 over RS485 with a CD4052 multiplexer inbetween, because those modbus devices somehow don't have a way to change their Slave IDs. The program switches through the channels of the CD4052 multiplexer to communicate with each of those modbus slave devices.
