Configuration Guide (AADvance Controller)
Create a Modbus Master Object
Note: You have to insert the Modbus Master Bus before you can carry out this task.
A Modbus Master object provides the configuration settings you need to add a Modbus
master capability to the AADvance controller. You have to create a new Modbus
master object for every group of multi-drop Modbus RTU slaves that use the same
serial port on the controller, and a new Modbus Master object for every Modbus TCP
slave on the network.
Do the following:
1) Select the Equipment tab on the Project tree view and locate the Modbus Master
Bus item.
2) Click the symbol beside the Modbus Master Bus.

The Modbus Master Bus item expands to show the three potential processor
modules in the controller.
3) Choose the processor module that will support the Modbus master object. This
will be the module associated with the serial port or the Ethernet port that you
intend to use.
4) Right-click on the desired processor item and select Add Master.

The AADvance Workbench inserts a Modbus Master object below the chosen
processor item.

The object is configured for Modbus RTU; you can change this later to
Modbus TCP.

The AADvance Workbench allocates a default name to the object; the name
includes the number of the processor module, with a serial number for the
object. You can change the name when you configure the object.

You can now configure the Modbus Master object.
