Hey Guys,
Apparently i need help for a project of mine. I am unable to continue as i am stuck with the Grafcet Process.. So, The operation goes like this..My project is about a automated rubbish collector.
I have the rough idea for the grafcet...the problem is , I am wondering if there is a PLC function that will allow me to measure distance? .. the thing is , when i first start operation , the gripper that will be gripping the part has a sensor to detect whether bin has been gripped or not , and after the throwing process , i need to return the bin to its original location , but how can i do that if i dont know the distance between my vehicle and the bin?...if i give the output for gripper to extend , it will extend to the fullest , and that is what i don't need.
i am not allowed to use Timers.
Please Help
