This logic group controls a lawn irrigation system that is divided into three sections.
The requirement for the control system was that not all three areas are irrigated at the same time.
Irrigation is started by the "Start" input, and the function is activated (with the value one) or deactivated (with the value zero) via the Lock input.
The time can be set by the user via the "Time" input. In the delivery of this logic group, the time for testing is set to five seconds.
If the run is started via the "Start" input, the outputs "Front area", "Middle area" and "Rear area" are set to the value one in sequence for the specified duration.
As a last step, the data point Start is reset to zero via the output "Reset" Start".
