RAPID variables and programs
Read and write RAPID variables and persistents, start and stop tasks, move the program pointer, load and save modules.// Read a RAPID variablevar counter = robot.Rws.Rapid.GetSymbolValue("RAPID/T_ROB1/MainModule/nCounter");Console.WriteLine(counter.Value);// Write it backrobot.Rws.Mastership.Request();robot.Rws.Rapid.SetSymbolValue("RAPID/T_ROB1/MainModule/nCounter", "42");robot.Rws.Mastership.Release();// Start the programrobot.Rws.Rapid.ResetProgramPointer();robot.Rws.Rapid.Start();Inputs / Outputs
List, read and write digital, analog and group signals. Pulse or invert a signal, and browse the I/O devices and networks.// Read every signal of the controllerforeach (var signal in robot.Rws.Io.GetSignals()){Console.WriteLine($"{signal.Name} = {signal.LogicalValue} ({signal.Type})");}// Read and write one signalvar gripper = robot.Rws.Io.GetSignal("Local", "DRV_1", "DO_Gripper");robot.Rws.Io.SetSignalValue("Local", "DRV_1", "DO_Gripper", 1);// Send 3 pulses of 500 msrobot.Rws.Io.PulseSignal("Local", "DRV_1", "DO_Gripper", 1, 3, 500, 500);Position and kinematics
Read the current robtarget and jointtarget, compute forward and inverse kinematics, and jog the robot.// Cartesian position of the toolvar robTarget = robot.Rws.MotionSystem.GetRobTarget("ROB_1");Console.WriteLine($"X={robTarget.X} Y={robTarget.Y} Z={robTarget.Z}");// Joint anglesvar jointTarget = robot.Rws.MotionSystem.GetJointTarget("ROB_1");Console.WriteLine($"Axis 1 = {jointTarget.RobotAxes.Axis1}");// Forward kinematics, without moving the robotvar toolFrame = new Pose(0, 0, 100, new Quaternion(1, 0, 0, 0));var pose = robot.Rws.MotionSystem.GetPoseFromJoints("ROB_1", toolFrame, jointTarget);Controller and backup
Read the identity and the options of the controller, set the clock and the network, create and restore a full backup.// Who am I talking tovar identity = robot.Rws.Controller.GetIdentity();Console.WriteLine($"{identity.Name} ({identity.Type}, {identity.MacAddress})");// RobotWare version and installed optionsvar system = robot.Rws.System.GetInfo();Console.WriteLine($"RobotWare {system.Version}");Console.WriteLine(robot.Rws.Controller.HasOption("Multitasking"));// Full controller backuprobot.Rws.Controller.CreateBackup("/hd0a/MyBackup");Console.WriteLine(robot.Rws.Controller.GetBackupState());File system
Browse the controller file system, download and upload files, create, copy, rename and delete files and directories.// Browse a directory of the controllerDirectoryListing listing = robot.Rws.File.ListDirectory("/hd0a/RobotWare");foreach (FileItem file in listing.Files){Console.WriteLine($"{file.Name} : {file.Size} bytes");}// Download a RAPID module and upload it backstring module = robot.Rws.File.GetFileAsText("/hd0a/MyProgram/MainModule.mod");robot.Rws.File.UploadFileFromText("/hd0a/MyProgram/MainModule.mod", module);Event log and state
Read the event log, follow the operation mode, the controller state and the speed ratio of the robot.// State of the robotConsole.WriteLine(robot.Rws.Panel.GetOperationMode());Console.WriteLine(robot.Rws.Panel.GetControllerState());Console.WriteLine(robot.Rws.Panel.GetSpeedRatio());// Last events of every domainforeach (var domain in robot.Rws.Elog.GetDomains()){foreach (var message in robot.Rws.Elog.GetMessages(domain.Number, maxCount: 5)){Console.WriteLine($"[{message.Timestamp}] {message.Type} : {message.Title}");}}IRC5 and OmniCore, one single API
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.
