Multi-storey car parks
One slave per floor with its own counter: when a floor is full, that floor's traffic light turns red.

Wi-Fi traffic light control unit
Saturno
From 1 to 10 traffic lights, from car parks to alternating one-way systems. Configured from your phone.
Available configurations
One master, one slave per traffic light.
Saturno is Stagnoli's control unit for coordinated control of 1 to 10 two- or three-light traffic lights. One master board for programming and one slave board for each traffic light, connected by a single RS-485 cable up to 1 km. It is configured from a smartphone, tablet or PC with a browser, by connecting to the master's local Wi-Fi network, with no software. It works in time-based, booking and mixed mode, and as a car park with free-space counting.
Time
Fixed cycles, even without sensors
Booking
Only the cycle of whoever calls
Mixed
Cascading cycles in the order of the calls

Count the spaces, control the traffic lights.
Each entrance or floor has a slave board with its own traffic light and two sensors; the master keeps count and shows it in the web interface. Try filling up the car park.

What happens
- EntryThe car passes over the IN1 sensor of the entrance slave: free spaces −1.
- RS-485 networkThe slave reports it to the master, which updates the single counter for all entrances.
- ExitThe IN2 sensor counts the car leaving: free spaces +1.
- FullWhen there are no spaces left all traffic lights turn red, until a car leaves.
- One floor, one slaveEach floor has its own slave, traffic light and space counter.
- Floor entryThe slave's IN1 counts the car entering the floor: floor spaces −1.
- Floor fullRed on that floor only: cars continue to the next floor.
- Floor exitIN2 counts the car leaving: the space becomes free again and the traffic light turns green.
- Programmed cycleEach traffic light has start, green, amber and red: their sum is the cycle time.
- One at a timeAt its start second the next traffic light turns green: never two greens together.
- Sensors ignoredWaiting cars do not change the cycle: only the set times count.
- Emergency and stand-byThe master inputs stay active: all flashing red or all red.
- Stand-byWith no calls all traffic lights stay red.
- CallThe slave's N.O. sensor books the green for its branch.
- Area clearanceBefore the green, the set clearance time elapses.
- Only that cycleGreen and amber on the branch that called, then stand-by again.
- Stand-byWith no calls all traffic lights stay red.
- Starting from the callerArea clearance, then green on the branch that called.
- CascadeCalls received during the cycle get a priority index and follow in order of request.
- EndWith no more calls: final area clearance and stand-by.
Each entrance has its own slave: IN1 counts who comes in, IN2 who goes out.
Demo of the «Car park» logic from the Saturno manual: global counter (several entrances, a single area) or per traffic light (one counter per floor). The SPACES/FULL sign is an example of a load on the slave's auxiliary output.
Time, Booking and Mixed: three-branch junction with one slave and one traffic light per branch; times shortened for the demo (green 6 s, amber 2 s, area clearance 2 s; in time mode start 0, 10 and 20 s on a 30 s cycle).
The interactive simulator is designed for larger screens: open it on a computer or tablet to try the logics, sensors and emergency.

Local point-to-point network, with no Internet connection.
Real-time status
Lights on, sensor inputs and emergency for every traffic light.
Easy programming
Start, green, amber and red for each light, with the cycle bar always in view.
Emergency states
Behaviour in stand-by and emergency, for example all red flashing.
Preset configurations

Fields of application
Where Saturno works.
The typical systems from the manual: all that changes is how many slaves you need and which logic you choose.
Several entrances, one area
All entrances update a single counter: when spaces run out, red on all traffic lights.
Car park · global
Alternating one-way systems
Two or more traffic lights with presence sensors: green to whoever books, after clearance.
