SMC_ReadSetValues (FB)¶

FUNCTION_BLOCK FINAL SMC_ReadSetValues

Reads the set position, velocity, acceleration, and jerk of an axis. Allows setting a positive TimeOffset to read future set values. With TimeOffset = 0 the set values from the beginning of the current cycle are read.

Note

Reading future set values requires setting a ForecastDuration using SMC_SetForecast.

InOut:

Scope	Name	Type	Comment
Inout	`Axis`	AXIS_REF_SM3	Reference to the axis
Input	`Enable`	`BOOL`	Read the set values continuously while enabled.
Input	`TimeOffset`	`LREAL`	Time offset relative to the current cycle for which the set values should be read. The `TimeOffset` must be between 0 and the ForecastDuration set using SMC_SetForecast. If the `TimeOffset` is outside this range the error SMC_INVALID_PARAMETER is reported.
Output	`Valid`	`BOOL`	`TRUE`: Valid outputs are available.
	`Busy`	`BOOL`	`TRUE`: Execution of the function block has not been finished yet.
	`Error`	`BOOL`	`TRUE`: Error has occurred within the function block.
	`ErrorID`	`SMC_ERROR`	Error identification
	`Position`	`LREAL`	The set position
	`Velocity`	`LREAL`	The set velocity
	`Acceleration`	`LREAL`	The set acceleration
	`Jerk`	`LREAL`	The set jerk
