I need you on the plant floor in Egypt to expand an existing Siemens S7-300 program by roughly twenty new points of mixed I/O. The work is purely control logic— no additional safety layer— and must integrate cleanly with the current STEP 7 project. Once the code is in place, create a single WinCC operator page that displays and allows basic control of those new points. Keep the look-and-feel in line with the existing HMI screens so the operators do not notice any stylistic jump. Because this job involves downloading to the live PLC and verifying signals on the physical panels, I can only accept someone who already resides in Egypt and can be on site for commissioning. Deliverables • Updated S7-300 program with the twenty mixed I/O points fully documented • One WinCC screen (runtime and source) linked and tested • Short handover report: tag list, network changes, and any address re-mapping carried out Acceptance criteria • All new points read/write correctly from the field devices and WinCC without forcing • No diagnostic or compile errors in STEP 7 after import • Operators confirm the new HMI page follows our existing navigation and color codes We will agree on a schedule that allows you to finish the logic, simulate, and then spend a single day on site for final commissioning and sign-off.

Hello, I understand you need an experienced professional in Egypt to expand your Siemens S7-300 program with about 20 new mixed I/O points, focusing on control logic without changing the safety layer. My approach would be to first carefully update your STEP 7 project ensuring the new points integrate smoothly without errors. Next, I will create a WinCC operator page that matches your current HMI style to keep the system user-friendly for operators. After testing and simulating the program fully, I will be on-site for commissioning, confirming all signals work correctly and operators approve the new HMI screen. I will also provide clear documentation including tag lists and network changes for a smooth handover. Are there any specific naming conventions or standards currently used in your existing STEP 7 and WinCC projects that I should follow? Best regards,
