Project description:
"I have an existing Ladder program for a three-belt system in the VirtualMakTOP “Cintas Transportadoras” model, but it needs a complete overhaul. Using Siemens TIA Portal you will restructure the code, add clear rung comments, and build a clean sequential control routine that transfers boxes between conveyors C1, C2 and C3.

Core requirements
• Three fully tested transfer sequences
• Industry-standard Provisional Pause (PP) and Emergency Stop (PE) routines
• Timers (TON, TOF, TP) and counters (CTU, CTD) used where appropriate
• Visual status indicators that show current conveyor position, active sequence, and any error messages

All development and testing must be done inside TIA Portal with VirtualMakTOP; no substitutes are acceptable. The deadline is 28 November 2025, and the job is a small fixed-price engagement, so efficiency matters.

When you reply, please confirm:
1. You have working access to both TIA Portal and VirtualMakTOP.
2. Your past experience creating conveyor or similar sequencing logic.
3. That you can deliver by the stated deadline.

I’ll supply the existing program and simulation files as soon as we agree to start." (client-provided description)
