Connecting Zeiss CMMs via MTConnect

1. Overview

This guide explains how to enable MTConnect connectivity on Zeiss Coordinate Measuring Machines (CMMs) for integration with MachineMetrics or other MTConnect-compatible monitoring systems.

Zeiss provides an MTConnect Data Interface that allows CALYPSO and PiWeb environments to stream standardized XML data directly to downstream systems. Once enabled, this interface reports CMM status, measurement cycle activity, and job execution events in real time.

Intended audience: Metrology engineers, IT administrators, and data integration specialists.
Why it matters: MTConnect integration brings CMMs into the same visibility framework as CNC machines, allowing real-time production analytics, automatic downtime tracking, and unified OEE reporting.

2. Feature Availability

3. How It Works

Zeiss’s MTConnect adapter runs as a lightweight service alongside CALYPSO. It converts machine-state and measurement events into MTConnect XML and exposes them via a local HTTP endpoint.

Typical Data Flow

1. CALYPSO controls measurement execution.
2. The MTConnect service reads event and machine-state data.
3. Data is made available at a URL such as http://<CMM-PC-IP>:5000/current.
4. MachineMetrics Edge polls this endpoint, normalizes the XML, and forwards data to the cloud platform.
   
    

Data items include:

• Machine status (Idle / Measuring / Alarm)
• Current part program name
• Measurement count and cycle time
• Operator ID (if configured)
  
   

4. How to Enable MTConnect on the Zeiss CMM

A. Prerequisites

• CALYPSO 7.2+ installed and licensed.
• Active Zeiss MTConnect Data Interface license.
• Windows 10/11 64-bit PC with network access to the MachineMetrics Edge device.
• Administrative permissions on the controller PC.
  
   

B. Install and Activate the MTConnect Adapter

1. Obtain the Installer
   • Request the Zeiss MTConnect Interface package from your local Zeiss support representative or through your Zeiss Portal account. Download free 60 day trial here.
      
2. Run the Installer
   • Execute as Administrator on the CMM PC.
   • Accept the default path (C:\Program Files\Zeiss\MTConnectAdapter).
      
3. Activate the License
   • Open the Zeiss License Manager and import the MTConnect entitlement file.
   • Verify that the MTConnect Interface service appears as “Licensed.”
     
      
4. Configure the Adapter
   • Launch the MTConnect Configuration Utility.
   • Set the machine name, HTTP port (default 5000 or 5001), and CALYPSO data path.
   • Click Apply and Start Service.
   • Test the local PC browser: http://localhost:5000/current → you should see XML output containing <MTConnectDevices> or <MTConnectStreams>.
     
      

5. Configure MachineMetrics Connection

1. In the MachineMetrics Edge portal, add a new MTConnect device.
2. Enter the endpoint URL of the Zeiss CMM (e.g., http://192.168.1.45).
3. Save and test the connection.
4. Once validated, you should see state transitions and cycle data updating in real time.
   
    

6. Verification & Testing

• Browse the endpoint URL directly to confirm live XML output.
• In MachineMetrics, confirm the device shows as Connected.
• Run a CALYPSO measurement program and verify the MTConnect XML updates accordingly (execution=ACTIVE, then COMPLETE).
  
   

7. Troubleshooting

8. Tips & Best Practices

• Use static IP addresses for all CMMs.
• Keep CALYPSO and MTConnect Adapter versions in sync after updates.
• Validate XML output with the official MTConnect schema to avoid parsing errors.
• Schedule service restarts weekly via Windows Task Scheduler for long-running installations.
