OdDataType Enum

Data types supported by the Object Dictionary (CiA 301 §7.4.7 Table 44, the data-type indices 0001h–001Bh a device description names). The fixed-width types imply their on-the-wire size (little-endian) for SDO expedited encoding and PDO mapping (FR-CO-001 / FR-CO-005); the strings and Domain are variable-length.

public enum OdDataType : System.Byte
