So I'm building a dual sided cell it has no positioners or external axis. It is simply just 2 fixtures 180 degrees apart robot in the middle. I am putting light curtains on both ends. How do I enter the cell on the side that isnt working to load fixtures. If I wire both light curtains to a relay and wire to the fence stop either side will trip it. I'm sure someone will know the answer. Thanks

Wire each light curtain to the extra DCS inputs on the DCS board. Then create two 'NO GO' areas for the two fixtures in DCS that are muted when the light curtains are safe. I recommend creating an internal safety relay using the safety I/O that allows the robot to move if the light curtains are muted or if the robot is in teach, so you can jog if out while standing in the light curtain.

Is Dcs the only way to do it. I don't have that option on the control.

Then you will have to do it the old school way, with safety rated cam switches on J1 to tell where the robot is. This will allow you to safely ignore the broken light screen if the robot is servicing the other fixture.

Check this out. This is what we used before DCS.
