Analogue (real) memory

Block name

B105_ANALOGMEMORY

ST call

PROGRAM TEST_B105
  VAR
 REAL0, REAL1,REAL2,REAL3,RAL4,REAL5 :REAL;
  SAVE :BOOL;
 FB: LIB.CORE.V1_0.B105_ANALOGMEMORY;
    END_VAR
     FB(CLOCKRISING := SAVE, IN0:=REAL0, IN1:=REAL1, IN2:=REAL2, OUT0=>REAL3, OUT1=>REAL4, OUT2=>REAL5);
END_PROGRAM

Library

LIB\CORE

Version

V1.0

Description

The block is a register of up to 16 real values. The values are stored at the rising (clockrising) or falling (clockfalling) edge of the input signal.

Inputs

Input	Type	Description	Default value
CLOCKRISING	BOOL	Rising edge copies inputs to outputs.	False
CLOCKFALLING	BOOL	Falling edge copies inputs to outputs.	False
INITIALIZE	BOOL	If initialize = true, then the initvalue is written to all outputs	False
IN	MULTIIOREAL	Input array from the *helper_multiinreal* block	[0,0,…,0]
INITVALUE	REAL	The value set to all outputs when initialize = true.	0
IN0,IN1,..,IN15	REAL	The inputs as individual values

Outputs

Output	Type	Description
OUT	MULTIIOREAL	Input array to the *helper_multioutreal* block
OUT0,OUT1,..,OUT15	REAL	The outputs as individual values

Function

The clockrising input reacts on the rising edge of the input signal which causes the inputs to propagate to the outputs. Similarly, the clockfalling input reacts on the falling edge of the input signal which causes the inputs to propagate to the outputs. If initialize = true, the initvalue is written to the outputs. Inputs and outputs may be connected in two ways, either through a multireal type to the in input, or individually to inputs in0,in1,….

Application example

A rising edge on the bool1 input copies the inputs to the outputs, or makes a “snapshot” of the input vector which is available at the outputs. Inputs and outputs are connected individually here, rather than using a multireal variable.
