Dashboard Server: remote commands

Power, brakes, programs, popups, robot mode and safety status of a UR cobot with the Dashboard Server of PolyScope 5. All the commands of the SDK.

The Dashboard Server of a Universal Robots cobot accepts remote commands on TCP port 29999: power on and off, release the brakes, load and play programs, show popups, read the robot mode and the safety status. This page lists the commands of the SDK for CB-Series and e-Series robots with PolyScope.

PolyScope X has no Dashboard Server: use the REST API.

Prerequisites

  • The service Dashboard Server is enabled on the robot: see Prepare the robot.
  • On e-Series, the commands that change the state of the robot (power, brakes, load, play) need the remote control: see Remote control. The commands that read a value work in local control.

Example

The Dashboard Server is enabled by default: Connect("192.168.0.1") opens it.

static void Main(string[] args)
{
var robot = new UR();
var parameters = new ConnectParameters("192.168.0.1");
// The Dashboard Server is enabled by default
parameters.Dashboard.Enable = true;
robot.Connect(parameters);
// Every command returns a CommandResponse
var powerOn = robot.Dashboard.PowerOn();
if (!powerOn.Succeed) Console.WriteLine(powerOn.Message);
robot.Dashboard.ReleaseBrake();
robot.Dashboard.LoadProgram("pick_and_place.urp");
robot.Dashboard.Play();
// Commands that read a value return a CommandResponse<T>
var running = robot.Dashboard.IsProgramRunning();
Console.WriteLine($"Running: {running.Value}");
// Close the Dashboard Server only
robot.Dashboard.Disable();
}
}

The same client works without UR:

static void Main(string[] args)
{
// A Dashboard Server client, without a UR instance
var client = new DashboardClient();
// Address of the robot. Optional: port, receive and send timeouts
client.Enable("192.168.0.1");
client.PowerOn();
client.ReleaseBrake();
client.Play();
client.Disable();
}
}

Responses

Every command returns a CommandResponse: Succeed says if the robot accepted the command, Message gives its answer. The commands that read a value return a CommandResponse<T>, with the value in Value.
