Hi, development support.

I found the bug on polyscope SW3.15.0

It is that value of gp output cannot be changed after setting action to none manually.

Please check this behaivor.

I confirm the behaviour on URSim 5.10 with @fujikit’s sample [Ethernet/IP I/O Monitor URCap](https://forum.universal-robots.com/t/urcap-sample-ethernet-ip-i-o-monitor-urcap-included-the-feature-of-rtde-and-xml-rpc-server-by-java/8724).

However if you write and read the gp output in URScript and save the value in a program variable you can see that they work even after setting “High when not running” and then “None”. Maybe there is a problem in your sample or in RTDE.

Hi  
I confirmed this problem also without my urcap.  
I sent the script from SocketTest App.

Hi @fujikit,

Thank you so much for letting us know! It seems like Polyscope does not send a _set\_runstate\_gp\_boolean\_output\_to\_value(0, 0)_ to the controller in this situation. I will report that internally.
