cos890.h File Reference

Detailed Description

The CiA 890 technical report defines the coding of SI units (international system of units) and prefixes to be used in CiA specifications. The predecessor document (CiA 303-2) was limited to CANopen documents.

This file holds definitions for the CiA 890 specification.

Parameters

[in]	SiPrefix	value defined by Cos890_SI_Prefix_e
[in]	SiNumerator	value defined by Cos890_SI_Unit_e
[in]	SiDenominator	value defined by Cos890_SI_Unit_e
[in]	Profile	reserved, always 0

The notation indexes represent hexadecimal code values for the ISO 80000 series’ physical units and prefixes in CiA documents, especially in device, interface and application profiles. The value structure of a configuration parameter, which determines the physical unit, should contain a notation index for SI prefix and notation indexes for SI unit as SI unit numerator and denominator.
