===== Library =====

LIB\CORE

===== Version =====

V1.0

===== Description =====

Shift register containing up to 24 analogue values.\\


===== Inputs =====

|Input|Type|Description                  |Default value|
|IN   |REAL|Input value                  |0            |
|BR   |BOOL|Shift by one (at rising edge)|False        |

===== Outputs =====

|Output   |Type                |Description           |
|OUT      |ARRAY[1..24] OF REAL|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.

===== Application example =====

The block is used for averaging, calculating of normalized outside temperature, bar graphs, peak shaving algorithms etc.
