In the General Configuration section of the Circuits/Manifold page, there is the possibility to connect to the circuit at issue (C1 C2 in the example below):
A main/father circuit
One or more interlocked circuits
...
The interlocked circuits, on the other hand, stop, so if on Page C2 we interlock C1 we interblock C2, when C2 starts C1 starts C2 stops. C2 C1 can restart, if there is demand, when C1 C2 stops.
