Building Shopfloor Workflow with Agent

Available inCloud

UNS agent provides a faster and easier way to build factory data models, connect data from factories and create alarm events based on the data through conversation in natural language.

Workflow Background

Section titled “Workflow Background”

A mixing tank mixes materials while heating them. Build a data model and collect temperature, water level, and heater status to determine whether the tank is overheated and trigger an alarm.

How to Build the Workflow

Section titled “How to Build the Workflow”

  1. Start a conversation with the UNS agent in UNS with full_access.

  2. Enter the prompt to build UNS models.

    Terminal window
    Create a data model representing the temperature, water level and heater status of a mixing tank, temperature and level in one metric topic and heater status in a state topic.

  3. Once you confirm that the model is complete, enter the prompt and let the agent connect the corresponding data to the model.

    Terminal window
    Create a source flow to send data to these 2 topics, simulate reasonable data.

  4. Enter the prompt to create an event with the following logic.

    • Low water level warning: Triggered when the water level is below 20% and the heater is on.
    • Dry-heating alarm: Triggered when the water level is below 15%, temperature is above 90°C and the heater is on.
    Terminal window
    Create an Event Flow for the following alarm logic:
      - Warning: Trigger when level < 20 and heater_status = true.
      - Critical: Trigger when level < 15, temperature > 90, and heater_status = true.
      - Clear the active alarm when level > 25 or heater_status = false.
    Create a new topic under the existing UNS model to receive the alarm result. Include the alarm level, message, active status, and timestamp in the output.

  5. Check the results on UNS.
