Use labels for multiple DAS setup

In your RPA setup, you may have multiple instances of the Desktop Automation Service (DAS) installed on different computers.

To connect multiple DAS instances to Design Studio simultaneously, you need to create separate devices for them. After that, ensure they are listed under Required Devices on the Action tab of the Call Robot step in the Basic Engine Robot .

When the DAS is installed on a desktop or a virtual machine, such a computer does not usually have an extensive set of software applications installed. Adding labels helps identify which software is installed on each computer and can be used by the Robot .

Later, when the Robot needs to automate a particular business application installed on the computer, the system finds an available DAS that provides all labels required by the Robot .

Possible scenarios include:

• Multiple setups are used with different DAS versions, while the business application to be automated can only work with a specific DAS version.
• Different desktops may be set up with different platform versions (Microsoft Windows), which may impact the Robot configuration.

Follow the procedure below to assign labels.

1. Start the Desktop Automation Service from the Start menu. Once the service starts, you can see its status by looking at the icon in the notification area.
2. Right-click the Desktop Automation Service icon in the notification area and click Configure. This action opens the Desktop Automation Service window.
3. On the Management Console tab, in the Labels field, type the labels. In the example below, the DAS is installed on a computer that has Microsoft Windows 10, the Microsoft Edge browser, and the Team Foundation Server (TFS) application installed. The labels must be separated by commas and must not contain any spaces between the comma and the next label.

   Within your organization, you can create any labels, without any limitations.

   
4. Click Save and Restart.
5. Check that the device is registered in the Management Console under Admin > Devices.
6. Launch Design Studio.
7. Right-click the required project in the Projects list and select New > Automation Device Mapping.
8. In the New Device Mapping screen, name the new mapping and click Next.
9. Ensure that Management Console Based Device Mapping is selected and type the required labels. In the example below, the Robot is going to automate the TFS application on a computer with Microsoft Windows 10 installed.
10. Finish the configuration and map the Robot to this device.
