I’m building a brand-new automation line around a Siemens S7-1200 and want the PLC logic and SCADA layer designed, written, and tested end-to-end. The core of the job is green-field development, yet I’m already bumping into three recurring headaches—communication drop-outs between devices, erratic sensor feedback, and a few stubborn programming errors—so the solution has to address those from the start rather than as after-thoughts. You will have full access to the plant topology and component list, and I’ll provide a clean namespace, I/O map, and the partial tags I’ve drafted in TIA Portal. What I expect back is a rock-solid S7-1200 program, a WinCC (or compatible) SCADA screen pack, and evidence—either through simulation files or on-site commissioning support—that the communication layer is stable, every sensor input is debounced and validated, and the code compiles without warnings. Deliverables • Completed S7-1200 project file in TIA Portal, neatly commented • SCADA configuration with live data points and alarms linked to the PLC • Test report showing no communication errors, clean sensor handling, and zero compile faults • Brief hand-over document so my maintenance team can step in confidently If you’re comfortable troubleshooting Profinet links, taming noisy sensors, and writing clean, modular PLC code, let’s get this system up and running.

I have reviewed your S7-1200 and SCADA requirements. Designing a greenfield automation line while proactively fixing Profinet drops, sensor noise, and compile errors is exactly my area of expertise. Here is my direct engineering approach to solve your three headaches: Stop Profinet Drop-outs: I will audit update times and watchdog factors in TIA Portal to mitigate network jitter. I'll use DeviceStates and ModuleStates instructions to auto-detect and report precise hardware faults instantly to the SCADA. Tame Sensor Noise: I will deploy software-based moving average filters, digital debouncing logic, and deadband limits within modular Function Blocks (FBs). Out-of-range signals will trigger immediate SCADA alarms before affecting the process loop. Flawless Code & SCADA Architecture: I will structure the S7-1200 logic using modular FBs and optimized UDTs (User-Defined Data Types) to ensure zero compilation warnings. The WinCC screens will map directly to these UDTs for fast, reliable data refreshing. Deliverables: Clean, commented TIA Portal project file. WinCC SCADA screen pack with live tracking and alarm logs. PLCSIM Advanced simulation test report proving zero errors. Maintenance-ready handover document. Quick Questions: Which version of TIA Portal are we utilizing? Are the current communication drops occurring with the SCADA host or with field devices like VFDs? Ready to look at your I/O map and tag list to get this line running flawlessly. Victoria
