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. 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 AttachmentTimers.pdf (187 Downloads) |

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

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
