Control logic
Programming manual and automatic operating modes, process sequences, start conditions, operational interlocks and fault-handling functions to the agreed requirements.
01 / PLC AND HMI PROGRAMMING
Precise control.
Reliable operation.
We develop PLC programs and HMI interfaces for Siemens and Beckhoff controllers, for both new equipment and existing production systems. We tailor the control logic to the process requirements, with particular attention to clear operation, fault diagnostics and long-term maintainability.

01 / THE TASK
Developing new control systems and modifying existing programs
We primarily work with Siemens SIMATIC and Beckhoff control systems, using TIA Portal and TwinCAT. Our experience ranges from stand-alone workstations to production systems with multiple PLCs, including the control and communication integration of robots, servo drives and machine vision inspection systems.
Operator interfaces
Clear industrial HMI interfaces with status indications, parameter settings and operator functions. We also develop bespoke Windows-based HMI applications using C#/.NET WPF, tailored to the task.
Diagnostics
Detailed status and fault messages, device diagnostics and troubleshooting functions to help locate problems faster and make equipment easier to operate.
02 / WORKING TOGETHER
From requirements
to implementation.
- 01
Requirements review
We review the process, hardware, source projects, access permissions and development environment versions. For existing systems, we agree on communication links, required backups and the impact of changes on production.
- 02
Functional specification
We define manual and automatic operating modes, operating sequences and start conditions. We agree on process fault handling, restart conditions, operator requirements and the data to be displayed on the HMI.
- 03
Development
We create the PLC program and HMI screens to the agreed functions and any customer programming standards. We develop clear, structured programs, using a modular approach where appropriate, with diagnostics to support troubleshooting.
- 04
Verification
Functional trials check input and output signals, operating modes and process sequences. We test fault scenarios and restart behaviour; FAT/SAT testing is also carried out where required and agreed.
- 05
Handover
We organise the project files and agreed documentation so changes remain traceable. We explain operation and troubleshooting, and agree the conditions for future maintenance and support.
03 / HANDOVER
Clear results.
Documented solutions.
We define the exact handover scope at the start of the project, tailored to the task.
At the end of development, we hand over the PLC and HMI project files, documentation of the implemented functions and changes, and verification results within the scope agreed in advance.
Our aim is to keep the control system’s operation understandable, the program maintainable and the system ready for further development. The functional description and diagnostic guidance help maintenance teams locate faults.

05 / FREQUENTLY ASKED QUESTIONS
Frequently asked questions
Which control platforms do you work with?
We work with Siemens SIMATIC S7-1500 and ET 200SP CPU controllers in TIA Portal, and with Beckhoff PLC systems in TwinCAT. We confirm the hardware type and software version at the start of the project.
Do you modify existing PLC programs?
Yes. Feasibility depends on the available source project, access permissions, software versions and the condition of the equipment. After reviewing these and the required operation, we agree on the changes, necessary checks and production conditions.
Can HMI development be commissioned separately?
Yes. We prepare operator interface development around the PLC connection, available data and operator requirements.
What does the on-site work include?
The scope, conditions and schedule for on-site checks, commissioning and support are defined as part of the project.
Do you provide PLC troubleshooting and production support?
Yes. We help troubleshoot existing Siemens and Beckhoff controllers, identify program faults and make targeted changes. We agree on the options and conditions for intervention based on the equipment, available access and production environment.
