NexaWork – PLC Programming, HMI Engineering & Commissioning Worldwide

NexaWork offers practical engineering support for machinery and equipment, from PLC programming and HMI engineering to virtual commissioning and on-site commissioning worldwide. We provide flexible support for partial scopes or complete projects and work with Siemens, Rockwell/Allen-Bradley, and CODESYS. Additionally, training and coaching help to build expertise within the team and sustainably embed engineering standards.

SPS Engineering

NexaWork– SPS / PLC Engineering

With NexaWork, we support you with SPS/PLC programming for machinery and equipment, from the basic structure, sequence controls, and motion, to diagnostics, alarm handling, and interfaces. Clear software architectures, traceable modules, and a clean project structure form the basis for robust, maintainable, and efficiently expandable control software. Depending on the project, we take on partial scopes, complete software packages, or specifically reinforce existing teams during peak phases.

Using structured PLC software, we demonstrate how basic functions, modules, interfaces, and diagnostic blocks can be clearly designed and logically organized.

HMI Engineering

NexaWork – HMI Engineering

With NexaWork, we develop HMI solutions that specifically improve operation, transparency, and diagnostics in everyday project work. Instead of purely functional screens, we create visualizations with clear user guidance, understandable status displays, a clean alarm concept, and practical service functions. This transforms the HMI into a real tool for operators, maintenance, and commissioning, not just an interface with buttons and messages.

On the HMI, machine states, operating modes, and process steps are visualized in a way that allows operators to quickly understand what the machine is currently doing and why.

HMI Engineering - Your Benefits

  • Improve usability in everyday operation


    Clear user guidance and comprehensible visualization reduce operating errors and facilitate safe handling of the system.

  • Diagnose malfunctions faster


    Well-structured alarm and diagnostic displays help identify causes more quickly and carry out service calls more efficiently.

  • Better support for operation and service


    Manual functions, service images, status displays, and recipes are designed to provide practical added value in real plant operation.

  • Seamless HMI and PLC Integration


    When data points, messages, and operating logic are consistently structured, control and visualization work together much more stably.

  • Simplify later adaptations


    A well-structured HMI is easier to expand, better to maintain, and can be adapted more quickly for machine variants or subsequent projects.

VIBN

NexaWork – Virtual Commissioning (VIBN)

With virtual commissioning, we test control logic, processes, and interfaces early on, before the real system starts. In conjunction with simulation or a digital twin, functions can be tested in a structured manner, error scenarios can be safely run through, and on-site times can be significantly reduced. This makes commissioning more predictable, lowers risks, and makes coordination between software, mechanics, and project stakeholders much more efficient.

The PLC is coupled with a simulation or a digital twin so that plant functions can be tested in a virtual environment even before the real machine starts up.

Virtual Commissioning (VIBN) - Your Benefits

  • Detect errors earlier


    Problems in logic, sequences, and interfaces become visible before actual commissioning and can be rectified with significantly less risk.

  • Specifically reduce on-site times


    The more functions that are virtually checked in advance, the fewer iterations, rework, and unplanned delays will occur later on the construction site.

  • Perform tests reproducibly


    Virtual test environments create repeatable conditions that allow processes, error cases, and changes to be tested in a structured manner.

  • Improve project communication


    Software, engineering, project management, and the client can jointly evaluate functionalities earlier and make more informed decisions.

  • Making Commissioning More Predictable


    A well-prepared virtual testing phase reduces project risks, improves schedule control, and increases safety during plant ramp-up.

Commissioning

NexaWork – Worldwide Commissioning

With NexaWork, we support commissioning worldwide, from preparation and initial test runs to stable handover for operation. We not only assist with system start-up but also with fault analysis, optimization, interface clarification, and structured handling of open issues. Thorough preparation based on software development, testing, and virtual commissioning forms the foundation for faster and safer on-site commissioning.

Before commissioning, test benches, software versions, open points, and interfaces are prepared in such a way that on-site deployment can begin with a clear structure.

Training

NexaWork – Training and Coaching

In addition to operational project support, NexaWork imparts knowledge on PLC programming, HMIs, and virtual commissioning. Whether it's standards, structuring, testing strategies, diagnostic concepts, or specific tools: training and coaching help teams not only procure engineering expertise externally, but also build it internally and make it sustainably usable. This creates not only short-term relief but also greater long-term independence in project business.

In training courses and coaching sessions, software structures, standards, module concepts, and typical engineering principles are made comprehensible directly through real project examples.
