Modbus Client Point Manager
This view creates and edits proxy points under a client Modbus device. It is the default view on the container of a ModbusAsyncDevice, ModbusTcpDevice, and ModbusTcpGatewayDevice, as well as on any points folder under these Points containers.

To access one of these views, double-click the component node in the Nav tree or right-click the component and click .
NOTE: Unlike the point managers in many other drivers, the
Modbus Client Point Manager offers no learn mode. The protocol’s simplicity makes these functions unnecessary. Instead, you use the New button to create proxy points, referring to the vendor’s documentation for the addresses of data items in each Modbus device.
By default, only a few of the available columns in the Modbus Client Point Manager are enabled for display, notably Name, Out and Absolute Address. However, you may wish to change this by clicking on the Table Options menu in the table’s upper right. For example, during the configuration process you may wish to see Fault Cause and Data Source.
