Configuring serial properties

For ModbusAsyncNetworks and the ModbusSlaveNetwork you must configure a number of properties to match the serial communications requirements of the connected Modbus devices. This includes configuring serial properties and identifying the Modbus transmission mode (RTU or ASCII).

Prerequisites:

You know how the baud rate, data bits, stop bits, parity, and flow control settings the serial network requires.

Perform the following steps:

If you have not already done so, right-click the network node in the Nav tree and select Views > Property Sheet.

The Property Sheet opens.
Scroll down and expand and configure the Serial Port Config to correspond to device requirements.
Set the Modbus Data Mode property value, either Rtu (default) or Ascii, depending on network type.
Click the Save button.
While in the property network’s property sheet, review its global Modbus settings.
