Possible error codes

For this function block, the following values, among others, are possible for the ErrorId output:

Error(Hex)	Error(Dec)	Error type	Description
0x8145	33093	Function Block	Mapping of cyclic interface between NC and PLC is missing (e.g., AXIS_REF, AXES_GROUP_REF, ...). A reference used by the function block (e.g., to an axis, group, mover or other motion object) is not linked to the corresponding NC object, or its cyclic mapping is incomplete.
