hi
i am a learner working with siemens plc.I m trying to make a program , where i have to generate one index.When input1 gets high, the index starts from 0 and after 20 minutes it becomes 1.Same way when the input1 goes low, the index starts gettting decrease and after 30 minutes it becomes 0.
I was trying to start one timer as input1 goes high.and them i am dividing 20 with running time value so that when the running value of timer becomes 20 the output of divid block will come 1.
but it is not working.I think i am making some mistake.Please help me.
