Analysis
Process, source code, signals, communications and required behaviour.
Industrial automation
PLC controller programming
We create new control programs, develop existing applications and diagnose problems that affect the operation of machines and production lines.
New applicationsProcess logic from requirements to commissioning
Code developmentFunctional changes and structured software
DiagnosticsAnalysis of faults and incorrect behaviour
Service scope
Software built around the real process
We design PLC software from operating sequences, I/O signals, operator requirements and commissioning conditions. The code should deliver the required function and remain understandable for future service work.
- Control logic and automatic sequences
- States, interlocks, alarms and operating modes
- Communication with HMI, drives and field devices
- Software fault diagnostics and correction
- Extension and restructuring of existing code
- Functional testing, commissioning and documentation
Delivery
A controlled path from analysis to acceptance
Before modifying a live system, we secure its current state and agree on acceptance criteria. This reduces commissioning risk and makes the result measurable.
Programming and tests
Logic implementation, review of fault cases and functional verification.
Commissioning
Machine tests, acceptance of operation and delivery of current project files.
Applications
When PLC engineering support is useful
New machine
Complete logic, manual and automatic modes, alarms and HMI cooperation.
Process change
New steps, recipes, devices or a new method of exchanging information.
Difficult diagnostics
Recurring stops, unclear alarms or faults that only appear under specific conditions.
Legacy code takeover
Program analysis, structural improvement and a controlled development path.
FAQ
Common questions
Can you extend an existing PLC program?
Yes, provided that source files are available and a verified backup can be made. We confirm the scope after reviewing the code and the current machine behaviour.
Can you diagnose a fault without replacing the whole system?
Yes. We identify the cause first and propose a change proportionate to the risk and the expected outcome.
How do you limit production downtime?
We prepare and test changes before site work wherever possible. The commissioning plan includes backups, test order and a defined rollback path.
