For the RTDE interface can you please provide the return values of runtime\_state and their meanings? The documentation only says that it is of the type UINT32 and has the description Program state I have reverse engineered these states 1 - STOPPED? 2 - RUNNING? 4 - PAUSED? There is no documentation for this that I have been able to find. Is there a STOPPING and a PAUSING state? ---

It is not written about this in documentation in detail. I defined the following enum. Stopping : 0 Stopped : 1 Playing : 2 Pausing : 3 Paused : 4 Resuming : 5 ![runtime2](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/6/66daab046f863833ea9c082150a71876e5ce948e.png) ---

Thanks, did you test the remaining states by writing the return value to the console continually and manipulating the PolyScope program state? ---

Yes, that’s right. I comfirmed by testing on real robot.(UR3 CB-Series) ---

Anyway, state is “Paused” when robot is paused and protective stop. “Resuming” refers to the state in which program is resumed from protective stop.
