Inputs

Name	Type	Description
Slave	Type_Camming1D	Reference to the slave axis
Execute	BOOL	Read cam coupling information at rising edge
CouplingInfo	Pointer To CamCouplingInfo	Pointer to array of CamCouplingInfo structures to fill
NumberOfCouplings	UDINT	Capacity of the CouplingInfo array.

Outputs

Name	Type	Description
Done	BOOL	TRUE when the cam coupling information has been read successfully
Busy	BOOL	TRUE while the function block is executing
Error	BOOL	TRUE if an error occurred
ErrorId	UDINT	Error code
NumberOfCouplingsFound	UDINT	Number of cam table couplings found on the slave axis (at most 8). This can be larger than NumberOfCouplings, in which case only the first NumberOfCouplings of them were written to CouplingInfo.

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.
0x8148	33096	Function Block	Invalid input value. At least one input of the function block is outside its allowed range or inconsistent with the other inputs.
0x8151	33105	State	Command is not allowed in current axis state. If the axis has no controller enable, is in error or has been added to a group, some commands are not permitted.
