PLC Engineering
Overview
PLC engineering is the foundation of modern industrial automation. A well‑designed PLC system ensures stable machine operation, predictable behavior, and easy maintenance. My approach focuses on clean logic, reliable hardware, and structured diagnostics. Whether you need troubleshooting, upgrades, or complete PLC development, the goal is always the same: stable, safe, and efficient operation.
I work with a wide range of PLC platforms, including Siemens, Allen‑Bradley, Mitsubishi, Omron, Schneider, and Beckhoff. Every project is built with long‑term reliability in mind, using clear documentation and modular logic that can be expanded in the future.
PLC Programming & Logic Design
A strong PLC program is not just code — it is a complete engineering solution. I design logic that is:
• modular
• easy to understand
• easy to maintain
• fully documented
• optimized for performance
Typical tasks include:
• creating new PLC programs
• redesigning old or unstable logic
• converting programs between platforms
• adding new functions or machine modes
• optimizing cycle time and performance
My programming style follows industry standards and best practices, ensuring that your system remains stable and predictable.
Troubleshooting & Diagnostics
Machine downtime is expensive. Fast and accurate diagnostics are essential for keeping production running. I provide structured troubleshooting based on:
• signal tracing
• I/O analysis
• error logs
• safe state verification
• communication monitoring
• inverter and drive diagnostics
Whether the issue is electrical, logical, or related to field devices, the goal is always to identify the root cause quickly and restore normal operation.
PLC Upgrades & Modernization
Many factories still rely on outdated PLC systems that are difficult to maintain. I offer complete modernization services, including:
• migrating old PLCs to modern platforms
• replacing obsolete hardware
• converting ladder logic to structured text
• updating HMI/SCADA interfaces
• improving safety and reliability
Upgrading your PLC system increases stability, reduces downtime, and ensures long‑term support.
Communication & Integration
Modern automation systems depend on reliable communication between devices. I integrate PLCs with:
• HMIs
• SCADA systems
• inverters and servo drives
• safety controllers
• sensors and field devices
• industrial networks (Profinet, EtherCAT, Modbus, Ethernet/IP)
Clean communication architecture ensures that every part of the system works together without conflicts or delays.
Documentation & Support
Every project includes clear and structured documentation:
- I/O lists
- wiring diagrams
- logic descriptions
- safety functions
- troubleshooting guides
Good documentation reduces maintenance time and makes future upgrades easier.
Safety Integration
Safety is a critical part of PLC engineering. I design and implement safety logic using:
• safety PLCs
• emergency stop circuits
• door switches and interlocks
• light curtains and scanners
• STO (Safe Torque Off) modules
All safety functions follow international standards such as ISO 13849 and IEC 62061.
Why Work With Me
My engineering approach is based on:
• clean logic
• stable operation
• precise diagnostics
• long‑term reliability
• honest communication
• practical, real‑world solutions
I don’t overcomplicate systems. I build them to work — simply, reliably, and safely.
