FBD/LD/IL Element: Box with EN/ENO

Symbol:

The element is available only in the FBD and LD editors.

The box generally corresponds to the Box FBD/LD/IL element, but this box also contains an EN input and an ENO output. EN and ENO have the data type BOOL.

Function of the EN input and ENO output: When the EN input has the value FALSE at the time of the POU call, the operations defined in the POU are not executed. Otherwise, these operations are executed when EN is TRUE. The ENO output has the same value as the EN input.
