Indexing Cylinder

[RobertL 1]

Hi Folks, I'm retrofitting an old machine and I need to index two cylinders, cylinder #1 will be keep extended to hold the part in place while cylinder #2 is retracted. After a few seconds, cylinder #1 will retract to let the part go to the next position on a downsream conveyor and cylinder #2 will extend and retract for a feaction of seconds then cylinder #2 will extend to hold the part in place to repeat the sequence . In orden to acomplish this, I'm planning to use two timers to index the cylinder on extended/retracted positiion. Is there a better way to do this? I'm usin a MicroLogix 1200. I would appreciate any help. Thanks, Robert.
