I want write a example program with S7 Simatic manager.24 pieces digital output are exist.One strobe input for start and stop.Scenario:When strobe input is active then outputs are energised one by one ( energising,passing and waiting time will be adjustable).Like a shift register it must continuosly run.if Cycle is finished,after a wait time will work again.
Example program in Simatic manager

Here's an example program. DB1 contains the times and the Q addresses. Start the sequence with I0.0, stop with I0.1
I've added my solution to L D's project. My sequencer consists of 25 instances of FB5, "One_State". You'll find the sequencer in FB 10 "Sequencer". Again I0.0 and I0.1 for start/stop.
If everybody joins in we'll find out once and forever how many solutions there actually are. Tulip: We are not making fun of you it's just that a problem likes yours overloads a programmers mind with all the possible ways to go. See the extreme difference in L D's ultra compact solution, and mine. Another way could be by using the SRD, CAD, CAW instructions...

Thanks Bakkei
for your efforts.I tried your program it is okay but I can not change interval times ,because it continuously shift very short interval.May be I could not explain my example.When I give an enable system will run.Firstly q0.0 will be on ( rest are off)and this on time of q0.0 is adjustable,end of this time a timer will be triggered (waiting time for all of intervals)at the waiting time is finished q0.1 will be on (rest are off) etc...end of cycle ,that is q2.7 will be on and off,more after another a timer will triggered ,at the this time is finished start cycle again...

As far as I understand that's exactly what my program does. Check FB 10, it drives outputs Q4.0 - Q 6.7 as the outputs Q0.0 - Q2.7 are already used by L D's program.
- the i_Time_Pulse of a state defines how long an output is high
- the i_Time_Pause of a state defines the delay between two states.

LD program:
Qn on for 1 sec, off for 3 sec then
Qn+1 on for 1 sec, off for 3 sec, then
Qn+2 etc.
Bakkei program:
Qn on for 500ms, off for 1 sec then
Qn+1 on for 500 ms, off for 1 sec, then
Qn+2 etc.
What do you require ?

Some pre-hints !!I came up with 68438 ways - I'm glad this came up up as i needed an idea for the April puzzle
But how the figure of 68438 came anyway??
Do you mean you used PLCSim? In that case you should install the latest servicepack & hotfix. There is a known bug with the use of SFB4.
