One more thing you can do is to use a counter. One push of the button can move bit 1 in the counter (use logic ... if count value is one ...it is ON )next push adds one more and if the count value is 2 reset counter ( this is OFF ).. try this it works -Anshuman

Hello friends, I am new to Siemens programming and have started to learn LAD a few days back. I am using CPU 315 2DP. Basically now I am writing the small programs in OB1 block and then use Simulation to test it. My software version is Simatic 5.2. I know that one can use FC,FB, SFC,SFB,DB and other tools to make a good program. I need to crate these Blocks and then link the these blocks to my main program which I do not know how ? Can anybody tell me how it should be done preferably with an exmaple for me to understand easily.Some other examples for my learning would be highly apprecaited. My email is : anshumanpatra@yahoo.com Thanks in advance bapi
