The ModbusAsyncNumericPoint component is responsible for reading numeric values from the device. The component has to be placed under the ModbusAsyncDevice component.

The ModbusAsyncNumericPoint component

The ModbusAsyncNumericPoint component has the following slots:

  • Status: shows the point’s status;
  • Fault Cause: shows the fault cause description;
  • Fault Status: informs abou the point’s error status (true: point read error);
  • Enable: enables or disables the point (true: point enabled, false: point disabled);
  • Address Format: allows to set the register address format (Modbus, decimal);
  • Address: allows to set the register address;
  • Poll Frequency: allows to set the reading poll frequency (fast, normal, slow);
  • Reg Type: allows to set the type of reading the register (input, holding);
  • Data Type: allows to set the read register data type (Int: 16-bits, Long: 32- bits, Float: 32-bits float-point, SInt: 16-bits with the sign, Slong: 32-bits with the sign);
  • Out: the current value of the read register.

The ModbusAsyncNumericPoint component offers the following action, available in the context menu:

  • Read: enforces reading of the point.
