MLFB_PlsTimeFw

Description

This function block should be used in the command position path with ascending position. A dedicated comparator pipe block is needed. The Boolean output oPLS is set to TRUE if the position of the comparator has crossed the start position and a timer with iOnTime is started. When the timer has expired the output is set to FALSE. The function block is executed cyclically. The modulo position is considered. The function block has the possibility to compensate a delay time of the connected device, e .g. glue nozzles.

Arguments

Input

ibExecute	Description	Enable PLS
	Data type	BOOL
iDedicatedCmpID	Description	ID of dedicated comparator
	Data type	DINT
iStartPos	Description	Start position of PLS
	Data type	LREAL
iOnTime	Description	Time PLS is on
	Data type	TIME
iDelayTime	Description	Delay time for compensation
	Data type	TIME
ibForce	Description	Force PLS
	Data type	BOOL

Output

oPLS	Description	Position limit switch
	Data type	BOOL

Example

Timing

ST

//PLSOutput is True when chosen comparator passes 180 for 3 seconds a T#2ms delay

//Can also force the output to be true with ForceOuput variable

Inst_MLFB_PlsTimeFw( EnablePLS, PipeNetwork.COMPARATOR, 180, T#3s, T#2ms, ForceOutput );
PLSOutput := Inst_MLFB_PlsTimeFw.oPLS;
