Cycle 4

Type Function module

Input E	BOOL ( Enable Input)
T0 _ T3	TIME (run time of each States )
S0	BOOL (continuous cycle Enable )
SX	INT ( State if SL = TRUE)
SL	BOOL (asynchronous Load input)
Output STATE	INT (status output)
	CYCLE_4 generates theStates 0..3 if E = TRUE . The duration of each State can be determined by the time constraints T0..T3. The input SL starts when TRUE from a predetermined STATE SX. The input E has the internal Default = TRUE, so that it can also be left open. After a rising edge on E the module always starts with STATE = 0, and if E = FALSE, the output STATE remains at 0. With the input of S0 the cyclic mode is turned on, if S0 = FALSE the module stops at State = 3, if S0 = TRUE, the device begins to State 3 again with State 0.
