How To Turn on BG Logic on the Old-Style Teach Pendant (R-30iA)?

alive15 · February 14, 2019 at 7:03 PM

Good afternoon all,

I have a Fanuc R-30iA with a black and white, 1 display teach pendant. I cannot find back ground logic for some reason. I have a program that runs in the background which controls a conveyor (99% sure anyways). From my understanding, the robot controller was restarted at shift start, and since then, the conveyor was not indexing automatically, but was done manually by an operator via pushbutton. I have uploaded some pictures showing some settings on the particular program, but unsure what I may need to change? Maybe option 1 or 2?
Any help is appreciated, thanks!

I'm unsure if you can see the attachments, but I uploaded here also:

Have you tried MENU>SETUP>BG LOGIC to see if there are any background programs set up? What software version are you running?

Right, when I hit menu, setup, it does not show BG Logic. On the newer colored teach pendants, I can see BG logic, but on this old one I cannot. How do I check the software version for you?

MENU>ENTER will show the software and version

The solution was to abort the program and re-run it from the beginning. It then calls that program to run in the background. What happened, they turned off the robot this morning, and when they started back up, the tech knew the exact location the robot was at in the program, so he moved down to it and started from there. However, he skipped opening that background routine up, as it's in the first few rungs, thus causing it not to run.

However, I will still bring you the software version, as I would like to know how to enable it manually, instead of restarting the entire program, as I am sure there is a way to do this.

Thanks!

If BG Logic isn't available, it is possible to force the program to run when the system does a cold start. Set the system variable $PWR_NORMAL to the name of the program you'd like to execute. However....

I am not sure that background is what you need. It seems this program may have been executed from a RUN statement (multi-tasking) in a .TP program. Take a look in your programs and see what might be calling or running the code that controls the conveyor.

Great point! If you're multitasking your conveyor program probably has the header of the program to ignore pause and not have the run light on while it's executing, plus of course not have motion enabled. Then inside the program, there is just an infinite loop. Also, i don't think R30iAs have BG logic...I could be mistaken though and it may just be an option.

Add this program to your hotstart and cold start in your system settings. I normally make a program called HOTSTART and then run the needed background programs in there. That way the program is always executed whether it's called in the production program or not.
