Input Description¶
EN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | FALSE | TRUE/FALSE | - |
The input EN has to be driven in level triggered mode.
In order to enable the execution of the Function Block the input EN has to be set to value TRUE. It keeps on executing until the input EN is set back to value FALSE.
While it is executed its inputs are continuously evaluated.
