Planning for Modbus Master

You have to complete three activities to use the AADvance controller as a Modbus

master:

 Make the physical connections from the controller to the slave devices.

 Configure the characteristics of the serial ports (Modbus RTU only).

 Set up the project for Modbus master, and configure the application.

There are no interdependencies between these activities, and you can do them in any

order, but you have to complete all three.

Physical Connections for Modbus RTU

Modbus master RTU communications use the serial ports on the 9100 processor base

unit. There are two fundamental topologies possible:

 Point to point

 Point to multipoint (multi-drop)

Each of these topologies can use a full-duplex, 4-wire (plus signal ground) connection

or a half-duplex, 2-wire (plus signal ground) connection.
