 Hello,

  I not see very well your image but ... In OB1 is ok and in another call not function right?

 Maybe some Jump function before?

 Hi, thank you for your answer.
By the way, timer in FC310 active when timer in ob1 actived, and then it will active indicator as led. in my case there is no jump before and after timer function. i has tried to placed the jump after timer function go to timer function in fc310 and the result is nothing. when i want to see what happend in fc310, i must copy paste program from FC310 into OB01.  Although, meskipun logically it's no need to copy paste network like it.
