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.
