I've never had enough time to play with such issues, but in my opinion 4 points should be enough - robot knows it's circular, count properly and that should be it
But never tested it for many different cases.
The calculation itself you can do in PLC and then send the offset to points, no problem with that.
OK, I will try this. Thanks for your support.
The issue is I had kinds of productions, so the radius and height are not the same. I don't want to teach robot and store the positions every time. What I would like to do is send the position data from PLC include some offsets. Another point is if the circular radius is large, does 4 points enough? I didn't have robot on hand to try this, But as far as I know, if I have more points, the circular will be more accurate. Is that correct?
Display MoreWell... I always do it from hand - easy calculation if it's on the XY plane, 4 points needed, point 1 is the same as 4 and that's it.
eg. circle with radius 50mm:
L/J P[1] // X = 0, Y = 0
C P[2] // X = 50, Y = 50
P[3] // X = 100, Y = 0
C P[4] // X = 50, Y = -50
P[1]
Hello Mates,
May I know how do you guys set up the robot to make it running a perfect circular? I know I should divide the circular to several points then use C/Arc to run the robot to the points, but how I can calculate the points automatically? Is there any software to do that?

Hello All,
Anybody know if I can change the number of digital IO? I have 1024 now and I want to change to 2048. I got experience on the new R-30iB controller and now i want to do that on the Old version of the controller. The old controller version is V7.7. When i controlled start the robot and try to change it in the Program SETUP, it says out of range. is that caused by the controller itself? thanks!

Chris
Hello Guys,
how do you guys use the DCS safe I/O for Fanuc Robot? What do you normally connect to the Inputs and Outputs? E-Stops, Fence and Safety relays? I just cannot know how to start to use that? or in which conditions that we need to use it. thanks!
you can change the PR[x] positions and then pass the PR[x] to user frame.
Hello,
Did you have the AOA files that was able to share with me? I understand we can do that by PR and R. I just assume that if there is something happened, the robot may cannot know. For example, how the robot reset the R[X]? as soon as the pallet was not there? another one is that normally we will get 20 parts, but it's possible that at the end of the productions, there just 10 parts, how we can reset the R[X]? Manually reset or do you have any ideals?
Regards,
Chris
Hello mates,
I just got a project that need to use the robot to stack parts. The parts need to be 4X5 on the pallet. Should I bought a robot with palletizing function or I can get it by the programming. Does anybody have samples of that? Can anybody give me some suggestions or the sample programs. I would like to know how you guys deal with that. Thanks!

Chris
Just attached the picture.
Thanks for your help. But its's very strange that the UO[20] was the reserved signal, it should not turn off by itself, correct?
Is the robot working with some HMI that has direct access to IOs?
Or maybe there is a PMC / BG-Logic program running in the background, switching the DO[20] to OFF?
There is no PMC and BG logic running. The robot is directly communicate with the PLC via EIP
Very Sorry for that. It's not DI[20], It's DO[20].
Thanks for your reply, but the robot didn't have the error recovery function. any other suggestions?
Hello All,
I just found a strange issue on the robot program. when I run the program and set the DO[20] to on and wait for a while, it will be off by itself. Even I test it in the Manual and Step mode, the issue still happen, and in the step mode, i didn't run it to jump to other line, it's stay inLine 17, I have checked and there is no any BG logic running in the robot. I will attach the program and hope someone can give me suggestions. Thanks!
What communication protocol are you using?
Hello
Dnet,EIP and Profinet. I have the GSD for the Profibus.
What is the difference between using a PNS to call a program vs a style select?
Thanks
For my understanding, there is no so much difference. Style you can choose the program that you want, you don't need to name the program with a special name. PNS and RSR, you have to name the program as the RSRXXXX or PNSXXXX. And also, there just 8 PNS program that you can choose, for Style should be 32, and for RSR you are able to get more.
Hello Mates,
Does anybody know how to get the EDS file and GSD file for the Fanuc Robot? it's not possible to download from the Fanuc website. For EDS, I know that even we don't have we are still able to use the robot, but for the GSD files, i guess we have to get it for using the robot.
Regards
You need RsLinx as well, you need it to configure drivers on your workstation. Maybe you can skip that step somehow, but I don't know how.
I think you can configure without eds-file and input parameters manually, but I used the attached eds-file and it worked fine for me.
After install the EDS, the RSLogix 5000 still cannot create the fanuc robot module. Did you use the EDS for the rslogix 5000?
Can you go to MENU--->SYSTEM---->CONFIG and check the item 43, it should be REMOTE and also there is another one called ENABLE UI SIGNALS, it should be TRUE.
Thanks a lot all you guys. Learn a lot!
