Thanks Guys, I read a lot of things in the manual and tried several things. My biggest problem was figuring out the software works. ( probably still need a lot of help) but i finally got it. Here is the program that works, ( it includes STL, Special thanks to Bob) (Wayne, i am still trying to get your program into my old software.) 0 LD X0 1 SET S0 3 STL S0 4 SET M0 5 LD M0 6 OUT T0 K25 9 AND T0 10 OUT Y0 11 OUT T1 K65 14 AND T1 15 RST Y0 16 SET M1 17 RST M0 18 LD M1 19 OUT T2 K25 22 AND T2 23 OUT Y1 24 OUT T3 K65 27 AND T3 28 RST Y1 29 SET M2 30 RST M1 31 LD M2 32 OUT T4 K25 35 AND T4 36 OUT Y2 37 OUT T5 K65 40 AND T5 41 RST Y2 42 SET M3 43 RST M2 44 LD M3 45 OUT T6 K25 48 AND T6 49 OUT Y3 50 OUT T7 K65 53 AND T7 54 RST Y3 55 SET M4 56 RST M3 57 LD M4 58 OUT T8 K25 61 AND T8 62 OUT Y4 63 OUT T9 K65 66 AND T9 67 RST Y4 68 SET M5 69 RST M4 70 LD M5 71 OUT T10 K25 74 AND T10 75 OUT Y5 76 OUT T11 K65 79 AND T11 80 RST Y5 81 RST M5 82 RST M0 83 RST S0 85 RET 86 END Valves.txt

To All, Thanks for the Information. I am still reading, looking and trying different things. Since last night, my program had to change to add a dwell between the valves on time, a period when all are off, which i seem to have working with the following program. 1. waits three seconds, from time X0 is closed. 2. turns on Y0 for 7 seconds, turns it off 3. 3 seconds of off time then turns on Y1 for 7 seconds then off. 4. 3 seconds later turns on Y2 for 7 seconds, then off. I just cant seem to figure out how to make it reset itself yet. Inst mode: 0 LD X0 1 ANI C1 2 SET M0 3 AND M0 4 OUT T0 K30 7 AND T0 8 OUT T1 K70 11 OUT Y0 12 AND T1 13 RST Y0 14 SET M1 15 RST M0 16 LD M1 17 OUT T2 K30 20 AND T2 21 OUT T3 K70 24 OUT Y1 25 AND T3 26 RST Y1 27 SET M2 28 RST M1 29 RST C1 31 LD M2 32 OUT T4 K30 35 AND T4 36 OUT T5 K70 39 OUT Y2 40 AND T5 41 RST Y2 42 SET M3 43 RST M2 44 END ladder is in file attachment. All help will be welcomed! Thanks Again Randy

Hello, i am new to programming PLCs, and need a program to turn on and off outputs without outside input & Auto recycle if you will. ( once started recycle until stopped) i have the program running one cycle without an issue, what i cant get is it to reset itself without an outside input. Is it possible to do this? can anyone guide me to the programming steps needed. I am using melsec medoc 1.64b to program the plc. i included my program for your help. Thanks, Randy valve.zip
