MC_CamTableSelect (FB)¶

FUNCTION_BLOCK MC_CamTableSelect

This function block is designed for selecting the cam tables by setting connections to relevant tables.

Note

When the Done output is TRUE, the CamTableID is valid and can be passed to MC_CamIn.
The CamTable is not copied. Instead, a reference to the CamTable is passed to MC_CamIn via the CamTableID. Take care that the CamTable is not modified while MC_CamIn is active.

InOut:

Scope	Name	Type	Initial	Comment
Inout	`Master`	AXIS_REF_SM3		Reference to the master axis
	`Slave`	AXIS_REF_SM3		Reference to the slave axis
	`CamTable`	MC_CAM_REF		Reference to the cam description
Input	`Execute`	`BOOL`	FALSE	Rising edge: Starts the execution of the function block.
	`Periodic`	`BOOL`	TRUE	`TRUE`: Periodic `FALSE`: Non periodic
	`MasterAbsolute`	`BOOL`	TRUE	`TRUE`: Absolute coordinates, i.e. the zero position of the cam table domain will correspond to the zero position of the master axis. `FALSE`: Relative coordinates, i.e. the zero position of the cam table domain will correspond to the current position of the master axis on a rising edge of the `Execute` input. Note that for non-periodic cam tables, 0 must be inside the domain if `MasterAbsolute` = FALSE, otherwise `SMC_CI_MASTER_OUT_OF_SCALE` will be reported when MC_CamIn is started with this `CamTableID`.
	`SlaveAbsolute`	`BOOL`	TRUE	`TRUE`: Absolute coordinates, i.e. the zero position of the cam table codomain will correspond to the zero position of the slave axis. `FALSE`: Relative coordinates, i.e. the zero position of the cam table codomain will correspond to the current position of the slave axis on a rising edge of the `Execute` input. Note that if either `SlaveAbsolute` = FALSE or the MC_CamIn `StartMode` is `relative`, relative coordinates are used. In all other cases, absolute coordinates are used.
Output	`Done`	`BOOL`	FALSE	`TRUE`: Preselection has been done.
	`Busy`	`BOOL`	FALSE	`TRUE`: Execution of function block has not been finished.
	`Error`	`BOOL`	FALSE	`TRUE`: Error has occurred within the function block.
	`ErrorID`	`SMC_ERROR`	0	Error identification
	`CamTableID`	MC_CAM_ID		Identifier of the cam table be used for the function block.
