Siemens S7 PLC migration: S5 to S7-1500
Siemens S5 and early S7-300/ET 200M are end-of-life. GCG migrates to S7-1500 or S7-1200, including Statement List (STL) to Structured Control Language (SCL) conversion, hardware changeover and IEC 62443-compliant network segmentation.

Migration target
Where we migrate to
→
Siemens S7-1500 + TIA Portal V17/V18 + WinCC Unified
Software conversion
Existing program converted to modern IEC 61131-3. Recipes and parameter sets transferred.
HMI replacement
Touch panel replaces ageing CRT/TFT. Same operator logic, modern interface.
Fieldbus upgrade
Profibus or DeviceNet converted to PROFINET or EtherNet/IP. Remote I/O preserved where possible.
Track record
Completed refit projects
Completed refit projects on Siemens S7 machines, documented, with results.
