Description
The function brings 8 bits together to create an integer value.
Inputs
| Input | Type | Description |
|---|---|---|
| ENABLED | BOOL | Enable function |
| IN | ARRAY [0 .. 7] OF BOOL | Array of input values (bits) |
| IN0 | BOOL | First input (simple type) |
| IN1 | BOOL | Second input (simple type) |
Outputs
| Output | Type | Description |
|---|---|---|
| OUT | USINT | Output value |
Function
The block brings together the input bit values IN[0..7] to a USINT (unsigned short integer) output out.
Application example
At the example, simple type (BOOL) inputs are used rather than the input array of BOOLs. The block is used e.g. to create a unit status value, such as Off / On / Auto which corresponds to values of 0 / 1 / 2.
