About Modbus
Introduction
Associated manuals
Communication by Modbus allows data to be exchanged between all devices connected to the bus. Modbus is a protocol which creates a hierarchical structure
(one master and several slaves).
l l
The master manages all exchanges according to two types of dialog: the master exchanges data with the slave and awaits a response, the master exchanges data with all slaves and does not await a response
(general broadcast).
