Omnicore virtual controller (RW7) web service change to http in appweb.conf doesn't work

Hi all,

I recently started development on Omnicore project. I have created an robot simulation with RW7 Omnicore. And I would like to use the web service as I did in the past for RW6. 

And I found online that Omnicore is can support https and http where you just need to modify the parameter on appweb.conf listen port.

I tried to change the first parameters from:
#Listen -1
ListenSecure -1

to

Listen -1
#ListenSecure -1

But when I use Listen instead of ListenSecure, after reboot the virtual controller, I have error on controller

It doesn't have any issue when I switch back to ListenSecure. 

May I know did Omnicore required particular option to enable web service? 

And I couldn't find the virtual controller listening port from the netstat -aon | FindStr command as thread below. I am only able to get a response if I try on the robotstudio.exe PID instead of RobotVC.exe

And the webservice command doesn't work on the robotstudio.exe listening port.

Thanks for the help in advance.

  • Hello there,

    Thanks for pointing out some mistakes in the initial post. I have now corrected the post to contain correct information for OmniCore.

    So if you want OmniCore to listen on HTTP as well as HTTPS, you'll have to uncomment the Listen -1 and change the -1 to some open port. I wouldn't recommend disabling HTTPS on OmniCore as that would cause RobAPI exceptions in RobotStudio.

    Then, regarding "netstat -aon | FindStr", you should find the process Vrchost64.exe for OmniCore controllers instead and use that pid in the command.

  • Thanks Maxim,

    I am able to see the virtual controller listening port based on Vrchost64.exe

    My next roadblock is I tried a few command but all of them return with error 401 unauthorized. 

    I am using username : Default User; password: robotics 

    my curl command : curl -u "Default User":robotics "http://127.0.0.1:51000/rw/elog

    I set my listen port to 51000 and below is my netstat response on Vrchost64.exe PID

    Is this due to unauthorized account login?
  • It looks like the headers aren't correctly setup. The post you linked to in your initial post covers required header settings.
