Integer shift register
Block name
B111_INTEGER_SHIFT_REGISTER
ST call
PROGRAM TEST B111 VAR REAL1: REAL; BOOL1: BOOL; ARRAYINT: ARRAY[1..24] OF INT; FB : LIB.CORE.V1_0.B110_SHIFT_REGISTER; END_VAR FB(IN:=INT1,BR:=BOOL1,OUT=>ARRAYINT); END_PROGRAM
Library
LIB\CORE
Version
V1.0
Description
Shift register containing up to 24 integer values.
Inputs
| Input | Type | Description | Default value |
| IN | INT | Input value | 0 |
| BR | BOOL | Shift by one (at rising edge) | False |
Outputs
| Output | Type | Description |
| 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.
Application example
The block is used for averaging, bar graphs, consumption calculations, etc.
