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)
