Hi, I am quite new to Codsesy and am after some help on trying to come a basic problem. Long story short I'm saying to implement a timer to start timing when sensor 1 is triggered and stop timing when sensor 2 goes high, then calculate the average speed. The problem wants it to be completed in SFC but if you know how to complete it in ST or ladder I would be interested to learn. Any advice would be great. Thanks
