Siemens S7-1200 PLC HMI Integration

I am building a control solution around a Siemens S7-1200 and need the complete PLC program and matching Siemens HMI screens created in TIA Portal. All logic has to compile error-free, follow Siemens best-practice block structure, use symbolic addressing, and include clear comments so I can maintain it later.

Once we start I will share the I/O list, functional description, and network settings; you will return a single TIA Portal project that contains both the PLC and HMI configurations.

Deliverables
• TIA Portal project file (.ap13 or later) with PLC and HMI fully linked
• Export of all program blocks and tag tables
• Short PDF explaining program structure, tag mapping, and any special instructions
• Video or simulation showing each HMI screen driving the PLC logic

Acceptance criteria: the project downloads to my S7-1200 without faults, the Siemens HMI connects immediately, and every described function passes a brief FAT session carried out remotely.
