PRIO-063 Bad I/O asg error. How to fix?

Hello,

We have a pair of (used - new to us) Fanuc R-2000iA/210F robots with R-J3iB controls (Handling Tool Version V6.40-1K). I am currently getting a PRIO-063 Bad I/O asg error: Rack 85 Slot 21 error on both robots. It doesn't seem to affect them in their tasks/programs, but it's annoying seeing it on the screen (and maybe it does affect them in some way). After some research I found that Rack 85 is the ControlNet rack. These robots do not have the ControlNet cards installed. The programs I've created do not call these addresses at all. Under this error (http://alarmcodes.com/fanuc-ro…bad-io-asg-rack-d-slot-d/), it says to delete or update the assignments, but to this time I haven't been able to figure out how or where.

When I go to the I/O ControlNet board detail, I get:

Board: 1 Status: NOBOARD
Motherboard: Full-slot
Operation mode: ADPTR
Param Change Mode: NET ULK
Input error state: ZERO

When I checked the SUMMARY.DG file (which I found during my research), it shows RACK 85 SLOT 21 under the following I/O:

When I check the I/O Digital configuration, it shows:

# RANGE RACK SLOT START STAT.
1 DI[1-16] 1 1 1 ACTIV
2 DI[17-512] 0 0 0 UNASG

# RANGE RACK SLOT START STAT.
1 DI[1-8] 1 1 1 ACTIV
2 DI[9-512] 0 0 0 UNASG

(No range above 512).

So, how do I delete or update the assignments?

Thank you,

Andrew

To delete an assignment just go to your I/O config screen, cursor onto the line of the assignment you want to delete, press the DELETE button(above F4 i believe), and then press YES. I just did this in Roboguide to confirm the steps, but this was an R30iB controller so the steps or buttons might be a little different in the older R-J3iB controller.

I also use the SUMMARY.DG file alot. If I get a call about an issue with a robot I usually look there first in a robot's backup to get a good overview of the robot; IO config, options installed, software version, etc.

The address range listed (in the SUMMARY.DG file) for Rack 85, Slot 21 is not listed in the IO config, so I can't delete it (I tried).

Did you try to perform Cold Start of the controller ?

Many times.

Also you can clear ALL I/O assignment by going to:

MENU -> I/O -> Link Device

and than form softkeybar menu choose option CLR_ASG, than confirm that you want to clear ALL assignment and after this is done restart the controller.

But be aware this will clear ALL I/O, that means you need to set them again after restarting the robot. In your case it's not so many just one assignment.

I'll try this next week when the line is not running.

Thanks.

Remember that I/O changes require a robot restart.....

Is that a Cold Start on the controller or just cycling the power to it?

Quote from bidzej

I would first try to set the number of digital IOs to 1024 (controlled start -> PROGRAM SETUP Menu) and then, after a cold start, try to delete the assignments. You can set the number if IOs back to 512 when you're done.
Also, check analog signals for any non-zero configuration (Rack/Slot/StartPt).

Thanks bidzej. Unfortunately, my controller didn't have a menu under the Controlled Start to allow a Setup as you mentioned. BUT, because of what you mentioned, I was able to find a Variable under System/Variables called $MAX_DIG_PRT that I could set to 1024 (was 512). I did a Cold Start, deleted the I/O configuration that was assigned to the non-existant ControlNet boards, changed the variable back to 512, cold start and voila! NO BAD I/O rack assignment alarms anymore. Did this to both my robots and now I'm happy.

Thanks bidzej and to everyone with their suggestions.
