Defining a
Modbus
 Slave

The AADvance controller can operate as a
Modbus®
slave, supporting up to a maximum of 10
Modbus
 slaves on each processor module. A controller with three processor modules supports up to 30
Modbus
 slaves.
TIP: As a
Modbus
 slave device, the controller only transmits data upon a request from a
Modbus
 master and does not communicate with other slaves.
When configuring a controller as a
Modbus
 slave, select whether the slave uses a serial or Ethernet connection. The connection type affects the slave properties like the available protocols and ports.
To define a
Modbus
 slave
  1. In the
    Communication View
    , expand the required controller, and then expand the
    Modbus
    element.
    The
    MODBUS Slave
     and
    MODBUS Master
     elements are displayed.
  2. Right-click the
    MODBUS Slave
     element, and then click
    Add New Slave
    .
  3. In the
    Communication View
    , double-click the slave instance, then in the
    Communication
    property page, select the connection type and define the required properties.
