ABB robots expose Robot Web Services in two versions. The SDK covers both, so the same code runs on an old IRC5 and on a new OmniCore. Only one connection parameter changes.

Short answers to the questions developers ask most often about ABB robots.
Frequently asked questions
Do I have to install something on the ABB robot?
No. Robot Web Services is a service of the controller itself, it is there on a standard system. You only need the robot to be reachable on the network and a user account allowed to do what you ask.
Does the SDK work on IRC5 and on OmniCore?
Yes. IRC5 controllers running RobotWare 6 expose RWS 1.0, OmniCore controllers running RobotWare 7 expose RWS 2.0. The SDK covers both behind one API, you only set the version in the connection parameters.
Do I need RobotStudio or the ABB PC SDK?
No. The library is 100% managed and talks directly to the controller. RobotStudio is only useful if you want to test against a virtual controller instead of a real robot.
Can I read and write RAPID variables?
Yes. You can read and write variables, persistents and constants, including robtarget and record types, and search the symbols of the loaded program.
Which .NET versions are supported?
From .NET Framework 3.5 to .NET 9, plus .NET Standard 2.0 and 2.1 and .NET Core 3.0. The asynchronous methods are available everywhere except on .NET Framework 3.5 and 4.0.
Can I move the robot with this SDK?
You can jog the robot, set a position target, and start or stop RAPID programs that contain the motion. Continuous real time motion control is the job of Externally Guided Motion, which is in development.
What comes next
Robot Web Services is available today. The other native protocols of ABB controllers, starting with Externally Guided Motion (EGM), are in development and will be added to the same SDK.
AvailableRobot Web Services
RAPID, I/O, position, controller, file system, event log and mastership, on IRC5 and on OmniCore.
In developmentExternally Guided Motion (EGM)
Low latency motion over UDP: position stream, position guidance and path correction, for sensor and vision driven applications.
Download and test
Windows application exampleAllows you to test all the features of the SDK with a simple interface. The example is compiled in "self contained" and "single file" with .NET 8. The application is portable without installation.

Libraries can be downloaded for free and can be tested for 30 days. After this period, you can ask us to extend the trial period, or buy the license that suits you best: standard, pro or source. After purchasing, you have a maintenance period, giving you access to the support and the possibility of updating. When you buy a license to use, it is linked to a robot brand, you can use it forever, without recurring fee, regardless of the number of robot, developer or software that you redistribute to your customers. If you are a distributor and wish to offer your customers one of our products, please contact us to discuss special conditions and prices.
