Hello,
I am dealing with RAPID variables that are overwritten by a backend program through REST API.
After the mastership is given in robotstudio + the RAPID program modified + mastership released, it sometimes occurs that the backend "looses" the subscription to some variables (not all) and can no longer change their value. However, when the controller is restarted, the subscription becomes ok again and any change of the variable is detected by the backend.

Are there any known issues with REST API and connection loss to PERS variables, and recovery at controller restart ?

Hi,
Which version of RS are you using ? In v.20241.1 There is actually no "edit joint properties" from the tree structure in the explorer, after selecting a link (and not a joint)

Hi all,

This question has already been asked back in 2014 (https://forums.robotstudio.com/discussion/854…mechanism-model) and 2022 (RobotStudio sim Mechanisms: Editing the mechanism) and 2024 (https://forums.robotstudio.com/discussion/141…steriori#latest) but they all haven't been answered so far....
Is there truly still no possibility to edit a mechanism ? Such as modifying the joint limits/orientations ?

Quote from ColoradoTaco

Well I think the design intent with the ABB speed settings are that you write your move instructions at either an "ideal" speed, or a "fastest possible production" speed. The PERCENT adjustment is really just there to slow things down for testing purposes, or if you have a temporary equipment issue that requires running at a lower speed.

A lot of people will program everything they possibly can at V3000 or VMax, then run at 50%, but it's not really good engineering practice, and ABB tech support would definitely scold you for it.

If I may ask... why do you find it necessary to alter you program speed so frequently?

I see, thank you or this explanation ColoradoTaco !
The reason for changing the speed frequently is that in the framework of extensive testing, I want the operator to be free to variate the speed his own way during the robot moves (so as one would do with ArcRefresh and welddata for example)

SkyeFire thank you very much too for this clarification about on the fly !

Very helpful answers

I would like for an operator to be able to set a desired velocity via an external PC, more like a speed dial then.

So I guess the interrupt version is the adequate one. I am unsure if the update is effectively considered once a MoveL xxx,speedxxx ... has been set for example. I'll try it out.

Still, it feels a bit unlogical to me to have a speedrefresh function that only enables speed reduction and no speed increase... Anyway

I've checked the Hot Edit window more in depth and it seems like it is only made for target position update, by the way, but no speed update

Thank you so much for your input ColoradoTaco !

Hey,

Thank you for your message however, my goal is to change the speed on the fly e.g. while the robot is moving, which I think is not possible with your suggestion... Do you see any other alternative ?

Hello,


I am trying to find a way to increase the speed dynamically upon the same principle of VelSet and SpeedRefresh.
For instance, I would like to be able to override the current speed and set it to 110% for example.
Is there an alternative to initially setting a nominal speed twice as fast as desired on purpose, and using Velset based upon that larger virtual nominal speed ?


Thanks in advance for any suggestion
