About this Gig

Welcome to my Siemens TIA Portal PLC & HMI Gig!

Need reliable, fail-safe automation logic? I develop industrial-grade solutions using Siemens S7 controllers and HMI panels.

Unlike software-only programmers, I have hands-on experience with real-world hardware and instrumentation. I build robust architectures that protect equipment and optimize processes.

What I offer: Function Blocks (FB): Reusable code for motors, valves, and sensors. Fail-Safe Logic: Hardware interlocks, auto/manual modes, hysteresis, and alarm timers. Analog Processing: Precise scaling (NORM_X/SCALE_X) for PT100/4-20mA sensors. Modern HMI UI: Operator-friendly Dark Mode, Trend Views, alarms, and multi-screen navigation. Testing: 100% logic verification using PLCSIM. Optimization: Organized Global Data Blocks (DB) and clean I/O tags.

Why choose me? Hardware-Aware: I prioritize interlocks to protect physical drives and contactors. Clean Code: Well-commented, scalable Ladder logic (LAD).

Please contact me before placing an order to discuss your project!
