Service de robots

Vue d'ensemble (Overview)

The Robot uses a Windows service that always runs when the machine is powered on. This service maintains a consistent connection with the UiPath Orchestrator to ensure the Robot can accept and execute jobs anytime. Some of the main capabilities of the Robot Service are:

• Inter-process communication (IPC)—Once you run an automation, the Robot Service receives and breaks down the process data into actions that the Robot Executor can understand and perform. This is done through communication channels that let different software parts on the same device share data.

• Connection to Orchestrator—The Robot Service maintains steady contact with the Orchestrator, constantly updating it with its operating status and receiving new instructions. It sends a heartbeat to Orchestrator, a signal that indicates the Robot Service is online and functioning.

• Session and credential management—The Robot Service manages Windows sessions, creating isolated task environments for each robot. Concurrently, the Robot Service upholds the security of sensitive data by managing the credentials for the Robot. In tasks requiring authentication, the Robot Service retrieves the necessary credentials securely, providing them to the robot.

• Operational modes—The Robot Service can operate in two modes - Service Mode or User Mode. These modes primarily differ in the way they are installed and operated, and the kind of tasks they tend to support.

Le service de Robot UiPath prend en charge les automatisations non assistées et assistées, comme suit :

• Unattended automation—The Robot Service executes processes in the background, even on virtual environments or when the user is not logged in. It makes decisions based on predefined rules, and it is suitable for large-scale, high-volume tasks, which improves operational efficiency.

• Attended automation—The Robot Service works alongside a user providing help with routine tasks. These might be rule-based tasks that require human judgment, aiding accuracy and productivity.

UiPath.Service.Host.exe

Lorsque vous installez le Robot en mode service, UiPath.Service.Host.exe est le service qui gère tout ce qui a trait à l’exécution de la tâche en arrière-plan.

In Service Mode, the Robot runs under the Local System, meaning it starts together with the system.

The UiPath.Service.Host.exe service manages how and when the Robot opens a Windows session for execution, and is responsible for launching and maintaining the Robot Executor in those sessions.

UiPath.Service.Host.exe est un élément essentiel de la fonctionnalité Robot car il garantit que les processus d'automatisation sont exécutés correctement en arrière-plan sans nécessiter d'interaction de l'utilisateur. Il s'exécute indépendamment de la connexion d'un utilisateur.

UiPath.Service.UserHost.exe

UiPath.Service.UserHost.exe est un service lié au robot UiPath lorsqu’il est installé en mode utilisateur.

En mode utilisateur, le Robot s'exécute sous l'utilisateur connecté et ne peut fonctionner que dans une session Windows active. Il ne nécessite pas d’autorisations système spéciales et s’arrête lorsque l’utilisateur se déconnecte.

Le service UiPath.Service.UserHost.exe exécute les tâches planifiées par Orchestrator et démarre le Robot pour l'exécution de la tâche.
