Add a T3 delay after the normally open contact T2, and then add a T3 normally closed contact before the normally open contact X0.

Normally open contact T2 is closed, T3 starts counting, T3 counts up, normally closed contact T3 is off, the first row T3 is off and reset, normally open contact T0 is reset, similarly T 1, T2 and T3 are also reset at the same time, T3 is reset, resulting in normally closed contact T3 being on, and the first row is off 1 scanning cycle, which is equivalent to all returning to the initial state. Can realize the cycle.

Hope to adopt. . . . .
