  1. ABB SDK features: Robot Web Services for IRC5 and OmniCore

    RAPID variables and programs

    Read and write RAPID variables and persistents, start and stop tasks, move the program pointer, load and save modules.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // Read a RAPID variable
    var counter = robot.Rws.Rapid.GetSymbolValue("RAPID/T_ROB1/MainModule/nCounter");
    Console.WriteLine(counter.Value);
    // Write it back
    robot.Rws.Mastership.Request();
    robot.Rws.Rapid.SetSymbolValue("RAPID/T_ROB1/MainModule/nCounter", "42");
    robot.Rws.Mastership.Release();
    // Start the program
    robot.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.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // Read every signal of the controller
    foreach (var signal in robot.Rws.Io.GetSignals())
    {
    Console.WriteLine($"{signal.Name} = {signal.LogicalValue} ({signal.Type})");
    }
    // Read and write one signal
    var 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 ms
    robot.Rws.Io.PulseSignal("Local", "DRV_1", "DO_Gripper", 1, 3, 500, 500);
    }
    }
    Click to see the full code

    Position and kinematics

    Read the current robtarget and jointtarget, compute forward and inverse kinematics, and jog the robot.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // Cartesian position of the tool
    var robTarget = robot.Rws.MotionSystem.GetRobTarget("ROB_1");
    Console.WriteLine($"X={robTarget.X} Y={robTarget.Y} Z={robTarget.Z}");
    // Joint angles
    var jointTarget = robot.Rws.MotionSystem.GetJointTarget("ROB_1");
    Console.WriteLine($"Axis 1 = {jointTarget.RobotAxes.Axis1}");
    // Forward kinematics, without moving the robot
    var 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.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // Who am I talking to
    var identity = robot.Rws.Controller.GetIdentity();
    Console.WriteLine($"{identity.Name} ({identity.Type}, {identity.MacAddress})");
    // RobotWare version and installed options
    var system = robot.Rws.System.GetInfo();
    Console.WriteLine($"RobotWare {system.Version}");
    Console.WriteLine(robot.Rws.Controller.HasOption("Multitasking"));
    // Full controller backup
    robot.Rws.Controller.CreateBackup("/hd0a/MyBackup");
    Console.WriteLine(robot.Rws.Controller.GetBackupState());
    }
    }
    Click to see the full code

    File system

    Browse the controller file system, download and upload files, create, copy, rename and delete files and directories.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // Browse a directory of the controller
    DirectoryListing 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 back
    string 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.
    AbbController robot = new AbbController();
    robot.Connect("192.168.0.1");
    // State of the robot
    Console.WriteLine(robot.Rws.Panel.GetOperationMode());
    Console.WriteLine(robot.Rws.Panel.GetControllerState());
    Console.WriteLine(robot.Rws.Panel.GetSpeedRatio());
    // Last events of every domain
    foreach (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}");
    }
    }
    }
    }

  2. 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.

    ControllerRobotWareRobot Web ServicesConnection parameter
    IRC5RobotWare 6 and earlierRWS 1.0RwsVersion.Irc5_V1_0
    OmniCoreRobotWare 7 and laterRWS 2.0RwsVersion.OmniCore_V2_0
    HTTP or HTTPS is a separate setting on the controller, independent of this table.

  3. Browse the documentation

    Browse the documentation

    The documentation allows you to quickly start developing with the library. The same functionality is available in all supported languages.

  4. How-To articles

    Short answers to the questions developers ask most often about ABB robots.

    Robot Web Services overview

    Robot Web Services (RWS) is the REST interface of ABB robot controllers. One API covers RWS 1.0 on IRC5 and RWS 2.0 on OmniCore.

  5. 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.

  6. 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.

    Available

    Robot Web Services

    RAPID, I/O, position, controller, file system, event log and mastership, on IRC5 and on OmniCore.

    In development

    Externally Guided Motion (EGM)

    Low latency motion over UDP: position stream, position guidance and path correction, for sensor and vision driven applications.

    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.
