Inputs

Input	Type	Description	Default value
IN	INT	Input value	0

OUT	ARRAY[1..24] OF INT	Array 1..24 of outputs
SHIFTTIME	DT	Time of last shift

Function

The block is a shifting register; at each rising edge on the br input the input value in is saved at the first output out, and the output values are moved by one position higher. The value of the output 24 is lost. The shifttime output returns the time of the last shift.
