Virtual Commissioning as a service for machines and systems

With NexaWork VIBN, we operationally support mechanical and plant engineers with virtual commissioning as a service. Together with your team, we check control logic, processes, interfaces, operating modes, and error cases early on in the digital twin, so that real commissioning proceeds more predictably, structured, and significantly more efficiently.

Overview

Virtual commissioning as an operational service for more predictable plant projects

NexaWork stands for engineering services in everyday project work. In the field of virtual commissioning, this means: We don't just deliver a model or a test approach, but actively support you with the preparation, coupling, execution, and evaluation of your virtual tests. This transforms the digital twin into a practical working tool that enables project teams to identify risks earlier and significantly better prepare for subsequent commissioning. We accompany virtual commissioning from the test strategy to the operational validation of individual functions, sequences, and fault cases. Depending on the project, we test PLC logic, HMI behavior, interfaces, operating modes, restarts, and defined scenarios in conjunction with the digital twin.

Core Functions

What NexaWork VIBN as a service actually does

Test strategy

Structuring test strategies and test scopes

We support you in setting up virtual commissioning not only technically, but also methodologically. This includes test objectives, test cases, priorities, release criteria, and the selection of functions to be validated before the actual system startup.

Pre-check

Early validation of control logic, processes, and interfaces

In the digital twin, operating modes, sequences, material flows, manual functions, and interfaces can be tested early. This reveals errors in the PLC logic, inconsistent processes, or unclear handovers before they cause time and cost on the real plant.

Robustness

Specifically secure error cases, restarts, and special states

Critical situations such as malfunctions, edge cases, or restarts can be simulated virtually in a much more structured way than in real commissioning. This improves the robustness of the software and increases safety during subsequent on-site tests.

Practical integration

Making Digital Twins Operable in Projects

If a Digital Twin or NexaTwin already exists, we help integrate it meaningfully into the engineering and testing process. This transforms a visualization model into a reliable tool for software testing, coordination, and commissioning preparation.

Your Benefits

Why virtual commissioning as a service pays off in projects

VIBN makes control logic, sequences, and system behavior testable at an early stage and reduces risks before actual commissioning.

Early detection

Detect errors earlier and fix them more cost-effectively

Problems in processes, states, interfaces, or operating logic become apparent before the actual plant startup and can be corrected significantly more efficiently than under construction site conditions.

Time-saving

Reduce on-site times and commissioning loops

When functions have already been virtually tested and fine-tuned, real-world commissioning processes are more structured. This saves time, relieves teams, and reduces unplanned rework.

Planning certainty

Making test phases more predictable and secure

A structured virtual commissioning creates clear test stands, defined scenarios, and traceable results. This makes approvals more reliable and project progress more transparent.

Voting integrity

Improve interdisciplinary coordination

PLCs, HMIs, mechanics, design, and project management can jointly assess functions and fault patterns on the digital twin. This reduces misunderstandings and accelerates decision-making.

Workload reduction

Provide operational relief for internal teams

NexaWork takes on specific tasks in test preparation, execution, and evaluation. This frees up internal software teams, project managers, and commissioning engineers, giving them noticeable time for their other project tasks.

Typical Applications

Typical Use Cases for NexaWork VIBN

The service is particularly suitable for projects where real commissioning is complex, expensive, internationally distributed, or time-critical.

Examples:

Virtual testing of new machine and plant concepts before physical construction
Validation of PLC software, HMI, and interfaces before FAT, SAT, or site deployment
Preparation of complex sequences, operating modes, and restarts
Early testing of material flow, tracking, or process logic
Support for project peaks when internal teams cannot fully cover testing themselves
Using an existing Digital Twin as a practical test tool in the project

User

Who NexaWork VIBN is particularly relevant for

This service is particularly interesting for:

Machinery and plant manufacturer
Special machine manufacturers with complex processes and tight commissioning windows
Project Manager for Automation Projects
PLC and software teams who want to secure functionalities early on
Commissioning engineers who need a better prepared real plant
Companies that want to more closely integrate Digital Twin and engineering

Classification in NexaWork

Virtual commissioning as a link between engineering and real commissioning

Within NexaWork, VIBN connects upstream engineering work with downstream real-world commissioning. Based on PLC engineering, HMI engineering, and a suitable digital twin, testing phases can be brought forward, problems can be identified earlier, and projects can be organized with significantly better planning. This is precisely why the service aspect is crucial: NexaWork VIBN doesn't just deliver a model or a method, but concrete support in preparation, test execution, error analysis, and handover to real-world commissioning. This creates an integrated engineering service that reduces risks and significantly safeguards project success.
