What this covers
- Code audit — reading and documenting existing STEP 7 v5.x logic, including the blocks nobody has touched in fifteen years.
- Block conversion — STL and LAD blocks and data blocks rebuilt in TIA Portal SCL and LAD rather than machine-translated.
- Network migration — Profibus-DP to Profinet planning, bridging where a staged cutover is needed.
- HMI redesign — obsolete WinCC flexible panels rebuilt in WinCC Unified or Basic.
- Schematic update — revised terminal assignments, 24 VDC control distribution and terminal block layouts.
- Staged changeover — sequencing that keeps the switchboard in service, with fallback at each step.
What you receive
- Existing system audit report with the recovered logic documented
- Converted TIA Portal project, commented and structured for future maintenance
- Profibus to Profinet migration plan with outage requirements identified
- Updated control schematics and terminal schedules
- Commissioning and changeover procedure with rollback steps
Standards and references
Converted logic is structured to IEC 61131-3, with network migration to the applicable Profinet and Profibus specifications and schematics to IEC 81346 reference designation practice.
