ModbusNumRegister<T extends num> class abstract

A numeric register where type can be ModbusElementType.inputRegister or ModbusElementType.inputRegister. The returned device value (i.e. raw value) can be of type Int16, Uint16, Int32 or Uint32.

This raw value might be converted into an engineering value by this formula: engineering value = raw value * multiplier + offset

The string representation of the engineering value can have a unit of measure uom and rounded decimal places viewDecimalPlaces.

Methods

getMultipleWriteRequest(Uint8List bytes, {int? unitId, Duration? responseTimeout, ModbusEndianness? endianness}) → ModbusWriteRequest

Gets a write request from multiple register elements.

inherited

getReadRequest({int? unitId, Duration? responseTimeout, ModbusEndianness? endianness}) → ModbusReadRequest

Gets a read request from this element

inherited

getWriteRequest(dynamic value, {bool rawValue = false, int? unitId, Duration? responseTimeout, ModbusEndianness? endianness}) → ModbusWriteRequest

Gets a write request from this register element. value is set to the element once request is successfully completed. If rawValue is true then the integer value is written as it is without any value or type conversion.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

setValueFromBytes(Uint8List rawValues) → T?

override

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
