Communication Solution


The optimal solution for industry

  • Standard and safety-related communication over one bus system

  • Increased system availability thanks to redundant design

Benefits in the tunnel

  • Redundant and extremely robust structures can be established with PROFIBUS - the leading bus system in the automation environment


The open, vendor-independent Industrial Ethernet standard for automation - specified in the world's largest fieldbus organization, PROFIBUS & PROFINET International (PI)

  • PROFINET is 100% Ethernet

  • Maximum speed and precision in data transmission - even with high volumes

Benefits in the tunnel

  • PROFINET - the future-oriented network topology for I/O interfaces - opens up new possibilities for the bus architecture in tunnels

Industrial Ethernet Switches SCALANCE X

In a class of its own in every category

  • Flexibility thanks to a comprehensive portfolio with different designs and functional scopes

  • Fail-safe networks thanks to high-speed redundancy and redundant power supply

  • Configuration and diagnostics in STEP 7 / TIA Portal

Benefits in the tunnel

  • The SIMATIC switch components can be integrated into the overall configuration and thus enable system-wide configuring and diagnostics

  • The product portfolio encompasses industry-standard components for the tunnel area and industrial switches with office functionalities for central control rooms


Future-proof and low-cost telecontrol system based on SIMATIC S7 with internationally standardized communication protocols

  • Serial transmission IEC 60870-5-101

  • Ethernet (TCP/IP) IEC 60870-5-104
    - Data security through a time stamp at the data sourceĀ 
    - Time synchronization possible using the NTP or IEC protocolĀ 
    - Data buffer for bridging communication interruptions

Benefits in the tunnel

  • SIPLUS RIC opens up new possibilities in the cross-vendor connection of control rooms and automation components thanks to a standardized telecontrol protocol

  • The communication blocks merge seamlessly into the configuration and enable low-cost implementation of the telecontrol protocol in the controller
