Hi,

May I kindly ask some of your idea how to solve situation I have. What I need is to start motor at time=0 to the right direction, after 5 seconds it should stop and wait for 2 seconds, then it should run in left direction for 5 seconds.
This is one cycle.
All other cycles should be the same (repeat all the time).
Problem I see is related to reset timers at the end of the first cycle¸(in discrete logic i.e. using Omron digital timers I made solution by reseting timers at the end of first cycle and after that all works fine).

Everything I do produce in some moment that both outputs goes to 1 (which would lead to short circuit).

Can it be done using ordinary ladder and existing timers or it have to be done using something other?

Please find attached simplistic table of what I'm trying to do.

Any ideas how to do that will be appreciated.

Code should be run on LOGO! (never used until now).

Kindly regards,

Almir

I would like to share a solution (which i guess is the same with what you would like to have).

My circuit is based on the application example from Siemens (automatic shift register).

Thank you

 Hi ixo65,

this is great. Thank you very much.

It is very readable code.

Thanks again.

You guys rock.

Here is a possible solution proposed in FBD and in LAD.

 Hi karthikk,

your solution is great also, now I can see how to use shift register to achieve goal.

Thanks for fast reply and saving me.

Thanks again.

Best wishes.
