Jambo Posts: 13 Rating: (0)	Hi Folks, I have 8 inputs and 4 outputs, 4inputs switch on the coils and 4 switch off the coil through a SR flipflop (relay). Only one coil can run at anyone time and when one coil is switched off the next in line is switched on. Also ifone off the inputs to switch on a coil is activated then that coil takes priority. My problem is if more than one input to switch on a coil is activated then no coils are on! What I want is for the coil with the lowest number to run for a time before the next coil that has the input signal state 1 to run until all coils have run. I have tried to attach my program without any success. With LOGO it was possible to save it in my pictures then the file could be sent.

HelloJambo, I am not sure that I have understand your question correctly. For each coil (output) you have two different inputs. One for set and the other for reset the flipflop. Only one coil can run at any time. If coil 1 is being set and then being reset, the next output will not being set until the set input is triggered. So to do the above, you have to add an enable bit for each output in its set condition. In case of more than one set input is active, then the enable bit of the lowest number should be set, then its coil will be energized. If I understand your problem correctly, please see the attached pictures. Hope this helps. Attachment ex.zip (613 Downloads)
