Virtual Commissioning

realvirtual includes the functions for virtual commissioning in the browser: a running digital twin that is connected to the real or simulated controller and tested with it before the machine is built. No Unity installation and no separate simulation tool is needed.

The Laser Welding Assembly Station in the Commissioning workspace: the Operator Panel in AUTO on the left, the simulation controls and the SIM button in the top bar

Virtual commissioning is one of the use cases of realvirtual. It starts from a twin built in the Editor or exported from Unity.

FunctionWhat it providesDetails
Commissioning workspaceInspector, hierarchy, signals, CONNECT and the AI bridge in one workspace; can be opened or shared directly as a linkScreen and Modes, Sharing
PLC signalsInputs and outputs of the twin, named like the PLC tags and bound to drives, sensors and lampsSignals and Logic, Signal Binding
Controller connectionConnects the twin to a PLC, a PLC simulation such as PLCSIM Advanced, or a robot controller — over OPC UA, S7, TwinCAT ADS, Modbus, EtherNet/IP, MQTT and moreConnecting a PLC, Interfaces
Signal discoveryReads signals from a live connection or a symbol table, such as a TIA .sdf exportInterface configuration
Simulation / PLC modeSwitches between the model’s own logic and the connected controller; a controller takes over automatically when it writes its first outputSignals & Alarms
Operator panelThe machine’s control panel on screen — push buttons, selector switches, E-stops, stack light — wired to the same PLC signals as the real oneOperator Panel
Virtual PLCLogic steps, or a Structured Text program in the browser, that run the twin without a controllerLogic steps, Virtual PLC (ST)
ForcingHolds a signal at a fixed value to test a reactionSignal Binding
Collision detectionChecks moving geometry for collisions while the simulation runsCollision Detection
AI assistantReads and writes signals, drives and components of the running twin through the AI bridgeAI bridge

The Laser Welding Assembly Station uses these functions together: 193 PLC signals named like the station’s TIA tag list, a virtual PLC of eleven Structured Text programs, an operator panel and the Simulation / PLC mode.
