The MODBUS Serial Line protocol is a Master-Slaves protocol. Only one master (at the same time) is connected to the bus, and one or several (247 maximum number) slaves nodes are also connected to the same serial bus. A MODBUS communication is always initiated by the master.MODBUS APPLICATION PROTOCOL SPECIFICATION V1

Modbus RTU Protocol Overview. Modbus RTU is a master-slave protocol. This means that only one device, the master, is allowed to initiate communication. The other devices on the network are called slaves and they may only respond to the requests. Modbus RTU can support up to 247 devices on the same physical network.ESP-Modbus - ESP32-S2 - — ESP-IDF Programming Guide latest ...

Modbus is an industrial protocol that was developed in 1979 to make communication possible between automation devices. Originally implemented as an application-level protocol intended to transfer data over a serial layer, Modbus has expanded to include implementations over serial, TCP/IP, and the user datagram protocol (UDP).Modbus Communication Guide
The protocol uses the Modbus Remote Terminal Unit (RTU) transmission mode. In RTU mode, data is sent in 8-bit binary characters. The 8 bit even parity or 8 bit no parity data format must be selected when configuring the instrument communications. The data format is shown in the following table.(PDF) Modicon Modbus Protocol Reference Guide | Renato ...

MODBUS© Protocol is a messaging structure, widely used to establish master-slave communication between intelligent devices. A MODBUS message sent from a master to a slave contains the address of the slave, the 'command' (e.g. 'read register' or 'write register'), the data, and a check sum (LRC or CRC).Modbus - Wikipedia
