PROFINET Managed Switches for Industrial Automation

Administration and Diagnostics, Availability, Security, Data Transfer and Performance: An Overview of All PROFINET Managed Switch Functions

Administration and Diagnostics

Simplified Commissioning and Maintenance

Configuration and Diagnostics

Several options:
  • Configuration via Web-Based Management
  • Configuration via command line (SSH, Telnet, RS-232)
  • Network management via SNMP v1, v2c, v3
  • Support of MIB standards (Management Information Base)
  • Configuration through the device description file

DDM (Digital Diagnostic Monitoring)

  • Automatic detection of a connected SFP module
  • Detailed module information
  • Real-time monitoring
    • Temperature
    • Supply voltage
    • Transmitter power
    • Reception power

Monitoring and Diagnostics

Simplified maintenance:

  • Port mirroring: Mirrors the network traffic
  • LLDP: Automatically detects adjacent devices

Availability

Via Communication Redundancy

Media Redundancy Manager

  • Media Redundancy Manager (MRM)
  • Media Redundancy Client (MRC)
  • Switching time < 300 ms
  • Easy MRC/MRM configuration via GSD file or Web-Based Management
  • Acyclic PN diagnostics in the event of a fault
  • Cyclic PN diagnostics in the event of a fault

Media Redundancy Client

  • Media Redundancy Client (MRC)
  • Switching time < 300 ms
  • Easy MRC configuration via GSD file or Web-Based Management
  • Acyclic PN diagnostics in the event of a fault
  • Cyclic PN diagnostics in the event of a fault

Security

Absolutely Secure Industrial Networks

Firewall – Access Control List

Authorization only for the required services

Filtering data packets on the basis of:

  • A source MAC or source IP address
  • A destination MAC or destination IP address
  • A range of MAC or IP addresses
  • UDP/TCP source or destination ports

Data Transmission

Optimized PROFINET networks

Logical network disconnection

VLAN (e.g., per IEEE 802.1Q)

Segmentation in logical, virtual networks:

  • Broadcast limitation
  • Security improvement
  • Data flow prioritization
  • Subdivision of machines and office networks, for example

Performance

Streamlined ETHERNET Networks

Traffic prioritization and limitation

  • Faster transfer of important data packets through the switch
  • Prioritization of data packets per IEEE 802.1 Q
  • Limitation of the bandwidth or number of packets per unit of time per port
  • Increase in data transmission quality

Mastering Data Traffic

  • Stopping broadcast storms
  • Ensuring network availability
  • Limiting broadcast and multicast data flows (packets/time)
