Why isn't the sequence running past step 1?

Also SFB4 is not getting initialized? CASE SeqStepOpn OF 1: t_q_si_cmd := false; IF NOT t_fb_si_opn AND t_fb_si_cls THEN ST_SD_OPN_DLY := true; TON_SD_OPN_DLY(IN := ST_SD_OPN_DLY, PT := SD_OPN_DLY); SeqStepOpn := 2; M100.0 := true ; END_IF; 2: IF TON_SD_OPN_DLY.Q THEN t_q_sd_cmd := true; TON_SD_OPN_DLY(IN := false); SeqStepOpn := 3; M100.1 := true ; END_IF; 3: IF t_fb_sd_opn AND NOT t_fb_sd_cls AND NOT t_fb_ps_ok THEN ST_DV_OPN_DLY:=true; TON_DV_OPN_DLY(IN := ST_DV_OPN_DLY, PT := DV_OPN_DLY); SeqStepOpn := 4; M100.2 := true; END_IF; 4: IF TON_DV_OPN_DLY.Q THEN t_q_dv_opn_cmd := true ; TON_DV_OPN_DLY(IN := false); M100.3 := true; END_IF; END_CASE; ------------------------------------------------------------------------------------------ Split from sequence programming in scl..

This way you are sure that each step will last at least one cycle, which may be needed somewhere else For example: Step1 := (Start); Step2:= (Transision1_2); Step3 := (Transition2_3); ... Transition1_2 := Step1 && logic for transition Transition2_3:= Step2 && logic for transition

The trigger inputs to the timer blocks is all that needs to be in the case statement's individual cases. Turning a timer on in case 1 that needs to turn off when it is not in case 1 needs to be considered as well. If a timer needs to only be on while a particular case (sequence step perhaps in this specific topic) is active, prior to the start of the case statement, all timer inputs need to be turned off (set to false). Then only activate (set to true) the correct timer trigger input during each selected case (sequence step). sinhx Hello, I have used case statement only. However sequence is not working. Can you give it a try and find the error?
