Y_CA_MasterIndexLookup

This function block returns the array index value corresponding to the given master position.

Parameters

*	Parameter	Data Type	Description	Default
VAR_IN_OUT
V	CamTable	UINT	The most recent CamTableID create by Y_CamFileSelect or Y_CamStructSelect.
VAR_INPUT
B	Execute	BOOL	Upon the rising edge, all other function block inputs are read and the function is initiated. To modify an input, change the value and re-trigger the execute input.	FALSE
V	MasterPosition	LREAL	The position of the master axis for which the index in the cam table is required.	LREAL#0.0
VAR_OUTPUT
B	Done	BOOL	Set high when the commanded action has completed successfully. If another block takes control before the action is completed, the Done output will not be set. This output is reset when Execute goes low.
B	Busy	BOOL	Set high upon the rising edge of the Execute input, and reset when Done, CommandAborted, or Error is true. In the case of a function block with an Enable input, a Busy output indicates the function is operating, but not ready to provide Valid information. (No Error)
B	Error	BOOL	Set high if an error has occurred during the execution of the function block. This output is cleared when 'Execute' or 'Enable' goes low.
E	ErrorID	UINT	If Error is true, this output provides the Error ID. This output is reset when 'Execute' or 'Enable' goes low.
V	MasterIndex	UDINT	The array index corresponding to the master axis position in the Yt_MS_CamStruct structure.

• The MasterPosition input should be a value between the maximum and minimum values of the master’s position profile for the index value to be valid.
