CONNECT Overview
realvirtual CONNECT is the local gateway between controllers and realvirtual. It runs near the machine on a Windows IPC or edge PC, speaks the industrial protocol on one side and the realvirtual WebSocket protocol on the other, and streams live signals to browsers. Unity is not required in this path.
Because the gateway runs at your site, machine and process data never leave the local network. CONNECT can also serve the complete realvirtual viewer locally — it ships inside the executable — or supply signals to another realvirtual deployment.

CONNECT is deliberately signal-centric. The smallest thing it knows is a named signal — Boolean, integer or floating point. Drives, sensors, kinematics and HMI logic live in realvirtual, which keeps the gateway thin and every protocol bridge interchangeable.
What CONNECT does
Section titled “What CONNECT does”| Capability | Description |
|---|---|
| Virtual commissioning | Closes the loop between the digital twin and a real or simulated PLC: PLC outputs move the twin, the twin’s sensors and buttons are written back to the PLC inputs — see connecting a PLC |
| Protocol gateway | OPC UA, Siemens S7, MQTT, TwinCAT ADS, Modbus client and server, EtherNet/IP, Bosch Rexroth ctrlX, Keba, Festo AX / PLCnext, FANUC, Denso, ABB RobotStudio and SIMIT shared memory — see supported protocols |
| Bundled 3D HMI | The open-source realvirtual viewer ships inside the executable and is served on the same port — or you point a hosted viewer at the gateway instead, see where the viewer comes from |
| CAD conversion | Large STEP and JT assemblies are tessellated locally and returned as GLB — see CAD conversion |
| Data recording | Selected signals are written to InfluxDB and shown as history charts — see data recording |
| AI error diagnosis | Answers “what does this alarm mean?” from your own machine PDFs — see AI diagnosis |
| MCP server | One endpoint through which an AI assistant reads signals and operates the running HMI — see AI clients |
| Self-update | The gateway replaces its own program file with a newer signed build after you confirm it — see updates |
Quick Start
Section titled “Quick Start”- Download and start the gateway on a PC in the controller network.
- Open
http://localhost:5100or use Open realvirtual WEB in the tray menu. - Register once to activate the free tier.
- Add an interface and add its signals by browsing, importing or entering them.
- Load your model and confirm that live values arrive.
