Hi Sina.Saffaran , A timer starts only when a rising edge is detected at the S input. T1 only starts when the start button is activated. Add an extra condition : not A red. Same way as you did for B green and it will work. The last network (stop button that resets the start button) can be deleted. Kind regards, BV |

Hello, At the end of your program, you are trying to reset I0.0(start) That is not possible. Inputs can only be written by the hardware. Try set a M-bit with start and reset at the end again. attached pdf with Start stop and fixed timer problem as mentioned in above post (T3 needed reset too) Regards, Marcjan AttachmentFC4_forum.pdf (208 Downloads) |
