This DataType is a structure that defines the rotation (or heading) of an object relative to the base coordinate system. The format is ‘yaw, pitch, roll’ as defined for aircraft principal axes. Its composition is formally defined in Table 67.

Structure 
Subtype of Structure defined in OPC 100005. 
Yaw 
Double 
The yaw of the object, in the unit defined for rotational measurements, e. g. in radians between PI and –PI (or in deg between +180° and 180°). Rotation measured around a vertical axis. Reference (yaw = 0) is the Xaxis of the coordinate system 
Pitch 
Double 
The pitch of the object, in the unit defined for rotational measurements, e. g. in radians between PI and –PI (or in deg between +180° and 180°). Rotation measured around a horizontal axis. Reference (pitch = 0) is the direction of the yaw on the horizontal plane of the coordinate system 
Roll 
Double 
The roll of the object, in the unit defined for rotational measurements, e. g. in radians between PI and –PI (or in deg between +180° and 180°). Rotation measured around a horizontal axis pointing in the direction defined by yaw, pitch 
Its representation in the AddressSpace is defined in Table 68.
