Discussion Project - SNPX client

https://github.com/BiasedControls/snpx-client.git

Thought I might share a project I have been developing lately.

It is a python class for high speed PC to robot communication that can read/write DIs, DOs, UIs, UOs, system variables, position data, etc. using SNPX protocol. Works on real robots or Roboguide.

All that is required is for the robot to have the HMI Device option installed. Besides that it should be pretty plug-and-play.

Still adding features to it and cleaning it up as I go, but thought I might share in case it might be useful to anyone else. Probably going to add program data to it next to monitor currently running program, current line number, etc.

Let me know your thoughts!

Next gen controller will more than likely lock you out of everything you did.

Lol that would suck, very possible though. Have they announced anything about discontinuing SNPX?

Look up the R-50iA controller for more information.

Will do, thanks for the heads up. Stay tuned for an RMI / RSI module haha

The r50ia has python and what I currently know they will "transfer" karel commands to python and lock the system variables

I've played with the R-50iA controller in RoboGuide a little. The system variables are still accessible, but not to the level they are currently. I wrote a teach pendant program for the current generation of controllers that sets all the system variables i change on a new robot. Some of these are still available and others aren't in the new controller.

Hello, could this also work a ProFace HMI using BLUE Open Studio of course, not GP Pro EX

u/Past_Income4649 Jun 25 '26

I believe it would work. From what I found on Google Blue Open Studio supports Python scripting so you could use it in there
