WebOct 30, 2024 · As already noted, Modbus is a simple master-slave protocol. The master has full control of communication on the bus, whereas a slave will only respond when spoken to. The master will record outputs and read in inputs from each of its slaves, during every cycle, as shown in Figure 2. The slave devices do not “join” the network. dave tootillWebModbus is a serial communication protocol to control PLCs (Programmable Logic Controller) and RTUs (Remote Terminal Unit).
