Connecting OEE and CMMS: The Technical Guide to Closing the Loop

In the traditional factory, Production and Maintenance are often at war.

Production focuses on OEE (Overall Equipment Effectiveness). They track Availability, Performance, and Quality. When a machine stops, they scream, "Fix it!"

Maintenance focuses on CMMS (Computerized Maintenance Management System). They track Work Orders, Spare Parts, and MTTR (Mean Time To Repair). When a machine stops, they ask, "Why didn't you tell us it was vibrating?"

The problem isn't the people; it's the data. The "Diagnosis" (OEE) is disconnected from the "Cure" (CMMS).

OEE CMMS Integration is the technical bridge that closes this loop. It automates the flow of information from the machine controller to the technician's pocket, removing human latency and error.

Here is the technical guide to how this integration works and why Fabrico is uniquely positioned to execute it.

To stop the finger-pointing, you need a system where data flows in a continuous loop.

1. The Sensor (The Nervous System): PLCs, IoT sensors, or Computer Vision cameras detect a state change (e.g., stopped, slowed, overheated).

2. The OEE Module (The Brain): The system analyzes the data. Is this a scheduled break? Or is it a Functional Failure? If it's a failure, it impacts the OEE score.

3. The CMMS Module (The Hands): If the failure hits a specific threshold, the system automatically generates a Work Order and assigns it to a technician.

4. The Feedback: The technician fixes the issue and closes the Work Order. The CMMS sends a signal back to the OEE module to log the "Down Time Reason" accurately.

Most legacy CMMS platforms rely on Time-Directed maintenance (e.g., "Change oil every 3 months"). Reliability-Centered Maintenance (RCM) teaches us that this is inefficient. We should maintain based on condition.

By integrating OEE data, you can create Smart Triggers:

• Cycle Count Trigger: Instead of "Monthly," trigger the blade change work order exactly when the OEE module counts 10,000 cycles.

• Runtime Trigger: Trigger motor lubrication only after 500 hours of actual runtime, not just calendar time.

• Performance Trigger: If the OEE "Performance" metric (speed) drops below 85% for more than 15 minutes, auto-generate an "Inspect Feed Drive" work order.

Fabrico Advantage: Because Fabrico houses both OEE and CMMS natively, these triggers are built-in logic, not complex API scripts that break when you update the software.

Standard OEE software relies heavily on PLCs. PLCs are great at telling you that a machine stopped, but they are terrible at telling you why.

• PLC Data: "Error 404 - Motor Stop."

• Reality: A bottle fell over and blocked the sensor.

This is where Fabrico Computer Vision changes the game.

Cameras monitoring the line can detect the context of the stop.

1. Vision system sees a jam.

2. OEE module logs "Minor Stop" (impacting Performance).

3. Vision system verifies it is a simple operator clearing task.

4. Decision: Do NOT send a maintenance technician. Log it as an operational loss.

This prevents "Alarm Fatigue" for the maintenance team. They only get a work order when the Vision system or PLC detects a true mechanical fault that requires a wrench.

One of the biggest wastes of time in manufacturing is the "Morning Meeting" where Production and Maintenance argue over downtime codes.

• Production: "Maintenance took 4 hours to fix the pump."

• Maintenance: "No, we fixed it in 1 hour. You took 3 hours to restart the line."

With integration, this argument ends.

1. Fault Trigger: The machine faults. OEE timer starts "Unplanned Downtime."

2. Response: Technician scans the QR code in the Fabrico CMMS app. Status changes to "Repair in Progress."

3. Completion: Technician marks "Complete." Status changes to "Waiting for Startup."

4. Restart: Machine cycles again. OEE timer switches to "Running."

Fabrico captures the exact MTTR (Mean Time To Repair) versus the operational delay, giving "Paula" (Strategic Leader) accurate data for ROI analysis.

You don't need to rip and replace your entire stack to get this.

1. Step 1: Connect the Data Source.
   Fabrico connects to your existing PLCs via standard protocols (OPC UA, MQTT) or uses non-intrusive sensors/cameras if the machines are old.

2. Step 2: Define the Failure Modes.
   Using RCM principles, define which faults trigger which actions. Not every stop needs a work order. Configure the logic to filter out "noise."

3. Step 3: Train the Loop.
   Ensure technicians know that closing the Work Order in the app is what "clears" the downtime log. This enforces compliance.

You can try to achieve this by buying an OEE tool from Vendor A, a CMMS from Vendor B, and paying a consultant to glue them together with APIs.

Or, you can use a platform where they are already connected.

OEE provides the signal. CMMS provides the action.
