Serial (SerialPort)

The Serial component allows to configure the Modbus RTU communication over the RS485 port.

The Serial component

The Serial component has the following slots:

  • Status: indicates the current status of the component. If the component works properly, its status is OK; the component's status becomes Disabled if its Enabled slot has been set to false.
    • Available information: Disabled, OK.
  • Enabled: change of the slot's value enables or disables the component.
    • Available settings: true (enabled), false (disabled).

Note: By default, the component is enabled.


If the Serial component is disabled, the network configured to operate on the serial port defined in this component is also disabled.
