Industrial communication and networks: Configuration of a stable data exchange in a PROFINET network, including secure integration of machines with supervisory systems and plant databases.
Safety systems: Programming, validation and rigorous testing of machine safety functions based on the PROFIsafe protocol.
HMI/SCADA interfaces: Creating and generating operator visualizations strictly according to VASS guidelines in terms of graphics, navigation, and diagnostics.
Start-up and optimization: signal tests, technological start-up at the facility, connecting the station to the main line and precise optimization of cycle time.
Acceptance inspections and documentation: Preparation of as-built documentation, participation in the corporation’s technical acceptance inspections, and engineering support during the start of production.

Why entrust us with VASS PLC programming?

We fully understand the realities of production. We deliver code compliant with the VASS structure, combining the rigorous requirements of the automotive industry with many years of experience from factory floors. We have turned this practice into a repeatable implementation model. Thanks to the standards we have developed, we eliminate unforeseen risks and reduce the entire project to a clear, smoothly executed process.

Predictable implementation

A precise action plan is a guarantee of a smooth launch. We eliminate the risk of delays and unplanned downtime by following proven procedures at every stage of implementation.

Clear division of responsibilities: We precisely specify the assignees of each task. This eliminates decision-making delays during system startup.
Defined scope of work: Before the first lines of code are written, we write down a detailed implementation plan. You know in advance how the work will proceed and what to expect at each stage.
Start-up based on checklists: We implement the project based on rigorous checklists. Thanks to this, we are certain that no key detail will be overlooked.

Partnership approach

Implementing software that complies with rigorous standards requires discipline. To ensure timeliness and trouble-free acceptance, we base our collaboration on three pillars.

Technical lead as a dedicated supervisor: The project is led by an engineer responsible for the system architecture. They know the full context of the work and have decision-making competencies, which significantly facilitates technological arrangements.
Seamless international communication: We select a team taking into account the language competencies required when collaborating with foreign suppliers or partners. This ensures an error-free flow of information.
Practical feel for processes: Experience gathered on the shop floors allows us to understand the business and technological context of the client’s plant. We not only write code, but we advise on choosing the most optimal solutions.

Experienced team

We eliminate the risk associated with handing tasks over to random subcontractors. Implementation is carried out by our in-house specialists, which translates into full commitment, quality control and clear responsibility for the result.

Certified competencies in the automotive industry: We have certificate-backed knowledge of the programming and commissioning standards of the largest corporations. This guarantees a smooth conduct of acceptance procedures and full compliance with the investor’s requirements.
One team from analysis to commissioning: The same people design the software and deploy it on-site. This way we avoid errors at the interfaces between stages and smoothly hand the machine over for operation.
Clean code and efficient diagnostics: We combine attention to code readability with rigorous adherence to the standard. Thanks to this, plant engineers receive a clear design with a familiar diagnostic system, which reduces response time to failures to a minimum.
