PLC and HMI software
We bring PLC, HMI and field devices into one clear control structure.
SD Otomasyon builds field-ready control software for PLC programming, operator screens, drive and sensor communication, troubleshooting and commissioning. The goal is a system that operators can use and maintenance teams can understand.
Service scope
We treat the machine, panel and software as one working system.
PLC-HMI work is not only code writing. I/O structure, panel wiring, communication, operator use and maintenance access are considered together.
PLC programming
Readable PLC logic is prepared for machine movements, safety logic, manual/automatic modes and fault scenarios.
HMI screen design
Commands, status information, alarm pages and production parameters are gathered in a clean operator interface.
Communication and field devices
Drive, sensor, energy analyzer, remote I/O and Modbus-based device communication structures are planned.
Revision and commissioning
Existing systems are revised carefully when there are faults, missing documentation, old software or operator-use issues.
When is it needed?
We make software-side uncertainties readable before they stop production.
If the machine runs but troubleshooting is difficult, the operator screen is weak, communication drops or the system behavior is unclear after revision, a proper PLC-HMI structure directly affects production continuity.
- When a new machine or line needs a control architecture before commissioning
- When the old PLC program cannot be read, backed up or modified safely
- When the HMI screen does not give enough information to the operator
- When drive, sensor, Modbus or field device communication needs to be arranged
- When a safe and stable test is required after machine revision
Work process
During commissioning, we keep the logic clear and traceable.
Our aim is not only to deliver running software, but also to leave an automation structure that can be understood during maintenance and production.
Survey
The machine, panel, I/O and operating scenario are reviewed on site or through technical data.
Plan
Control architecture, communication, HMI screens and test steps are defined.
Software
PLC program and HMI screens are prepared in a serviceable structure.
Test
Manual, automatic, alarm and safe-stop scenarios are tested in the field.
Delivery
Operator use, maintenance intervention and backup information are clarified.
Technical topics
We shape PLC-HMI work around production, maintenance and commissioning needs.
PLC, HMI, recipe, alarm and reporting
Machine control software, operator screens, alarm management, recipe structure and production information are handled with one clear logic.
Drive, sensor and communication infrastructure
Modbus, Profinet, remote I/O, drive parameters and field device communication are arranged according to production needs.
Breakdown, revision and field commissioning
Support is provided for reading existing software, diagnosing faults, revising systems and commissioning in the field.
