Awesome. Thanks for all the help. I gave a rough picture to the local integrator and they are going to come take a look in person and then give us a price.

I guess where I am not understanding is how the EAS is working.

I am planning to have two separate relays, one for the door interlock and one for the light curtain. Where I am losing my understanding is with both contacts of the EAS.

I tried yesterday to pull the jumper on EAS 1-11 to see how the robot would react and what all we would need to do to reset it. EAS 12-21 was still jumpered. All of the contacts on that block are jumpered at the moment, that is how the controller came to us. After further forum searching my current understanding is that a fault occurs if EAS 1-11 and 12-21 are not switched at the same time. .

So if I had my door connected to EAS1-11 and light curtain connected to EAS 12-21. If my light curtain was not broken, but my door was open how is that any different that having the jumper pulled on EAS 1-11 and the jumper still in 12-21? Wouldn't that give me the same fault on the fence circuit as I had when I pulled one of the jumpers mimicing a door opening, leaving the other jumper in mimicing that the light curtain is not broken?

I have a call into our local integrator, now I am just trying to understand how this works for my own sake.

How do I wire the door interlock and light curtain both to the controller?

I think I can jump into the reset and cycle start buttons and run auxiliary push buttons closer to the light curtain. That would eliminate the need to walk to the robot controller for reset and cycle start. And would also eliminate the need for a plc if we just have the person pressing both buttons.

Now onto my next problem.

The way I am understanding is that I need two outputs from my safety relay for the door in EAS 1-11 and EAS 2-21 since they both need to activate / deactivate close in timing. So I take two separate outputs from my safety relay and run into those connections. (2 channel, 3NO safety outputs, 1 NC safety output) But then I am not left with any EAS connections for the light curtain to go into? I assume I also need 2 outputs from my light curtain for that to work correctly as well? Can I use the EGS as the same thing as the EAS? are the basically the same thing?

So if I do not have a PLC does that mean I would need to continue program from the teach pendant, or does the program need to be restarted from the beginning every time the light curtain is broken?

Can someone explain the Difference between the EEs, EAS, EGS, and SD on the estop board for an R30ia controller?

I have a system that is going to have a safety fence door interlock. I am thinking this should be wired into the EAS (Fence) board. My question is do I choose the controlled stop, powered off stop from the teach pendant or is it a matter of how the device is wired in? I am wanting the robot to stop once the gate is opened. Then I want it to have to be restarted from the controller when it is closed again.

I am also adding a light curtain to the system. When the light curtain is broken I would like the program to HOLD when the light curtain is broken. And then once the light curtain is no longer block and the reset button is pressed I would like the robot to continue on with the program automatically. Should the light curtain still be wired into the EAS board.

We do have the DCS software that came with the robot, but we have not gotten far enough with our programming to start messing with it. We bought the robot used. It is a R2000ib with the R30ia controller. This is our first attempt at using a Fanuc robot so we are still pretty green with it.
