How to Start Monitoring Okuma CNC for Free (2026)

Okuma machines running OSP-P300S, OSP-P500S, and OSP-P300L controls support MTConnect via a free adapter available from Okuma's developer portal. This guide covers the full setup - from downloading the adapter to seeing live OEE data - at no cost.

Okuma OSP controls and MTConnect support

Step-by-step: MTConnect setup on Okuma OSP

Step 1 - download the Okuma MTConnect adapter

Okuma provides a free MTConnect adapter through the Okuma App Store (apps.okuma.com). Log in with your Okuma account (free registration) and search for "MTConnect Agent." Download the installer for your OSP version (P300 or P500).

The adapter runs on the OSP controller's built-in Windows PC - no separate hardware required.

Step 2 - install and configure the adapter

1. Copy the installer to the OSP PC via USB or network share
2. Run the installer - it installs as a Windows service
3. Open the configuration file at C:\Okuma\MTConnect\adapter.cfg
4. Set the port to 7878 (MTConnect adapter default)
5. Set the device_name to identify your machine (e.g., "Okuma-VTM200")
6. Start the service: Windows Services → "Okuma MTConnect Adapter" → Start

Step 3 - deploy the MTConnect agent

The adapter produces raw data. An MTConnect agent (separate software) formats it into the standard MTConnect XML stream that monitoring platforms consume. Download the free MTConnect C++ Agent from github.com/mtconnect/cppagent, or use the agent built into MDCPlus.

If using MDCPlus: add a new machine, select "Okuma MTConnect," enter the OSP PC's IP address and port 7878. MDCPlus handles the agent layer internally.

Step 4 - verify data

Open a browser and navigate to http://[OSP-PC-IP]:5000/current (standard MTConnect agent port). You should see an XML document with the machine's current state, program name, and spindle data. If the XML returns valid data, your monitoring system connection will work.

What data Okuma MTConnect provides

Standard Okuma MTConnect implementation exposes: execution state (Active/Interrupted/Ready/Stopped), program name, spindle speed, feedrate override, axis positions, and active alarms. Part count is available on OSP-P500 and requires a specific configuration in the adapter config file - see the Okuma developer documentation for the part_count_register parameter.
