Modbus enables client/server communication between devices connected through buses or networks. On the OSI Model, Modbus is positioned at Level 7. It isAdditional cable diagrams and diagrams for multiple device serial networks can be found in the Pro-face Device/PLC Connections Manuals. Connect the BAS network cables to the appropriate ports. For an N2 or MS/TP network, connect the 3-wire bus cable to one of the removable 4-terminal blue plugs This document will discuss MODBUS RTU only. 5.1.1 Transactions on Modbus Networks. Modbus protocol uses a master–slave technique, in which only one device ( Each Modbus RTU network requires one master and one or multiple slave devices. The slave devices send information to the master device. HOW IT WORKS. Modbus is This document from DECK Monitoring suggests Engineering Standards for RS-485/Modbus RTU network wiring. DECK Monitoring provides information about The easiest and the best way to connect the devices in a MODBUS RTU – RS485 communication is using DAISY CHAIN method. It is shown below. Any other way of
