When ON, the initial step S0 is ON and Y0 is ON.2. When transfer condition X10 is ON (in actual application, the transferring condition may be formed bythe serial or parallel combination of the contacts X, Y, M, T and C), the step S20 is activated. Thesystem will automatically turn S0 OFF in the current scan cycle and Y0 will be reset automatically toOFF.i.e. X10 ON⇒S20 ONS0 OFF⇒X1 ONX2 ONY0 OFFY1 ONY2 ON3. When the transfer condition X11 is ON, the step S0 is ON, Y0 is ON and S20, Y1 and Y2 will turn OFFat the same time.i.e. X11 ON⇒S0 ONS20 OFF⇒Y0 ONY1 OFFY2 OFF8-6
