Table 59 shows references of standard data types and profile specific data types used by PROFIdrive (see [PDP], 5.2 and 5.3). The numeric identifier is the value of the first byte of the BMP parameter description “Identifier (ID)”.
If a conversion factor and an offset are to be applied for the display value (see [PDP], 6.2.1.3, Standardisation factor and Variable attribute), the OPC UA DataType shall always be 0:Float or 0:Double.
