Function: The command inserts an empty box with a Boolean input “Enable” and a Boolean output “Enable Out” at the end of the selected network.

Call: Main menu “FBD/LD/IL”, context menu

Requirements: The FBD editor, the IL editor or the LD editor is active. A network must be selected. No other box may be selected.

If “Enable” has the value ‎FALSE‎ at the time of the function block call, then the operations defined in the FB are not executed. Otherwise, if “Enable” has the value ‎TRUE‎, these operations are executed. The ENO output acts as a repeater of the EN input.
