Description
The block is a gate for logical signals.
Inputs
| Input | Type | Description | Default value |
|---|---|---|---|
| ENABLE | BOOL | If enable=true then out0=in0,... | False |
| IN0,IN1,..,IN15 | BOOL | Inputs, individually | |
| IN | MULTIIOBOOL | Inputs array | [False] |
Outputs
| Output | Type | Description |
|---|---|---|
| OUT | MULTIIOBOOL | Outputs array |
| OUT0,OUT1,..,OUT15 | BOOL | Outputs, individually |
Function
The block is a gate: if enable=true then all inputs are copied to outputs. If enable=false the outputs keep the last value. Note that the ST indeces range is 1 to 16 rather than 0...15.
