Industrial Automation & Software Engineering

Siemens engineering, from machine control to integration

GCG connects PLC software, operator interfaces, I/O and industrial networks into working machine controls. For new installations and existing S5 and S7 systems that need maintenance, expansion or modernization.

What we do on this platform

  1. PLC programming

    TIA Portal, S5 (legacy), S7-300/400/1500.

  2. HMI/SCADA

    WinCC Flexible and WinCC Professional.

  3. Drives

    Sinamics G120 drives, commissioning and parameterization.

  4. Networking

    PROFINET and PROFIBUS, up to 400+ stations in one network.

  5. Safety integration

    Aligning safety functions with the risk assessment, selected hardware and machine validation.

  6. Migration

    S5 → S7-1500, S7-300/400 → S7-1500 with TIA Portal.

Migration starts with understanding the running system

We first map the existing software, I/O, communication and operation. We then agree migration steps, testing and switchover with your production and maintenance team.

The choice of CPU or runtime is project-specific. Compatibility, required licenses and current product availability are checked before implementation.

  • S7-1200 G2

    A compact PLC for basic automation.

  • S7-1500 and Distributed Controllers

    Modular control or a compact combination of PLC and distributed I/O.

  • SIMATIC I/O

    Connecting field signals to the controller to suit the machine layout.

TIA brings together controllers, HMI, drives and engineering. The right combination depends on cycle times, signals, operation and maintenance.
