I have a manufacturing assembly line that needs a solid Siemens S7-1500 program so the whole process runs reliably without constant operator tweaks. The PLC will take charge of every step on the line—from feeding parts, through each assembly station, to final transfer—maintaining sequence, interlocks, and safety signals while logging key production data for our MES. You’ll be working in TIA Portal (latest V17 preferred, but I can migrate from V16 if needed). The deliverable I expect is a fully commented PLC project file, tested in the simulator first and then ready for onsite download. If you can include basic WinCC Unified screens for status and fault diagnostics, that’s a plus, but the core focus is the ladder/SCL logic that makes the line cycle smoothly. To accept the work, I’ll load your project into our test rack: each station must complete a full cycle without watchdog or safety trips, all I/Os must map exactly to the provided hardware list, and alarms should be clear and timestamped. Remote commissioning support over VPN rounds out the job.

Hello, i think i'm the best candidate to do this job and I will propose to you to do plc program + base HMI that we need to define togheter. I will start with make this bid for 37000 INR / day, and we need to make a plan of work based on days. To make an evaluation of effort in days I need electrical schematics and a P&ID diagram where i can see the process flow. We also need to be clear that this price / day is only for development phase, while commissioning support i will consider separetely and we can discuss in future. I have 10 years of commissioning experience, so I know how many difficulties can happen during that phase.

Hi, Albert here, from Philippines. Building your S7-1500 assembly line control with PLC comes down to one thing: a device that behaves the same in the field as on the bench. I'm a senior embedded and electronics engineer with 10+ years of experience working with Electronics and Electrical Engineering. With PLC, the real challenge is timing, power and real conditions. A common issue: testing only on the bench, so problems appear once the device runs in real conditions. My plan: first, review the schematic, pin map and timing requirements. Then, write the firmware in small modules, each tested on the board. Finally, test on the real hardware under load, power loss and bad signal. I've done firmware work before, so I check early for timing issues and power drops. A few questions to better understand the scope: 1. Should firmware update over the air? That needs a safe bootloader and a fallback image, planned from the start. 2. Use the vendor HAL except where timing is tight? I'd recommend it, easier to change, registers only where needed. 3. Will units run unattended for long periods? Then I add self-checks and logs that explain any failure afterwards. I can start right away. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you, Albert

kind regards, I can help develop the S7-1500 assembly line control around a clear PLC sequence, safe machine states, and reliable I/O handling. I’d structure the automation logic for sensors, actuators, interlocks, alarms, and operator control, then verify the sequence through simulation where practical. I can also prepare clear electrical and technical documentation so the final control design is easier to test, troubleshoot, and maintain.
