Can current position registers be updated from a program?

Search the forum for Explicit Message

What does the explicit messaging have with the OP question?
His problem is not reading the data, but the impossibility to override these data in the robot.

I not 100% sure but don't think you can simulate the current position data in the robot. Can you just create a program where the robot moves back and forth for testing?

I want to write a program on the robot controller to be able to set these robot registers through the program. I need this to simulate my robot - the program will update these positions without actually moving the robot. Is it possible? What do I need to do?

If this is something that doesn't need to happen all the time, you could turn off motion in the test menu. I believe the CURJPOS will updated with where the robot "believes" it is, not where it actually is.

I tried updating these values manually from the Kepware client, but they didn't change. So I assumed it was impossible. Or maybe I need to enable something on the controller for this?

They may have updated for a scan on the robot side, but then your background program probably immediately overwrote it.

I'm very new to robots and especially fanuc robots. We have R-30iB controller.

Our software communicates with the robot via a Kepware server. To get the robot's current position, we have 8 tag names mapped to robot registers that are updated as the robot moves.

Hello ,

To understand your requirements -

1.Do you want those reg value to be updated with out executing any robot porgram ? - well you can do by creating background program which update robot current position from robot variable --- that has robot current position or you can use instruction JPOS to get currnet joint positon ... this program could update all register value in real time --- some miliseconds delay !!

also , mask out any group in program details so your program can run in background wiht our affecting any other motion program

Also , does your software has difficutiles to read register value or your robot program can not update register values

If you can not update your tags with current updated register values , you can do some reasearch on explicit messaging ... we did get use those messaging to read and write direct postion register / register from Allen bradley PLC .. or you may need PCDK to get live robot data

Hope this helps ..
