Industrial Managed Switches: Function Overview

Administration and diagnostics, availability, security, data transfer and performance: An overview of all functions of the industrial managed switch

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, v2, v3
Support of MIB standards (Management Information Base)
Diagnostics via Modbus TCP: Numerous information available for easy diagnostics via MODBUS

DDM (Digital Diagnostic Monitoring)

Automatically detects a connected SFP module
Detailed module information
Real-time monitoring
- Temperature
- Power supply
- Transmission power
- Reception power

Monitoring and Diagnostics

Simplified Maintenance:

Port mirroring: Mirroring the network traffic
LLDP: Automatic detection of adjacent devices
Email notifications

Availability

Via communication redundancy

Jet Ring

Typical switching time < 300 ms (depends on the application)
Extremely easy configuration
Up to 20 participants (fast aging) in a jet ring

Xpress Ring and Dual Ring

Xpress Ring:

Switching time < 20 ms
Easy configuration
Up to 200 switches in one Xpress ring
Two Xpress rings per switch

Dual Ring:

Combination of both redundancy types
1 jet ring and 1 Xpress ring per switch or 2 Xpress rings per switch

ERPS (ETHERNET Ring Protection Switching)

The Fast and Open Solution:

Standardized and open technology
Switching time < 50 ms
Nested topologies with up to six rings per switch
Realization of a one-fault tolerance (SPOF – Single Point of Failure)

ERPS – Enhancement Mode:

WAGO's devices with integrated switches and fast aging configuration
Typical switching time < 300 ms (depends on the application)

Security

Absolutely Secure Industrial Networks

IEEE 802.1X Authentication

The Security Standard of IT Networks: Secure authentication and authorization in ETHERNET networks (locally on the switch or via RADIUS server).

Process:

Authentication of a subscriber is performed by the authenticator.
The authenticator checks the authentication information of the subscriber (supplicant) with an authentication server.

Firewall – Access Control List

Authorization only for the required services

Filtering data packets due to:

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

Port Security

Dynamically learns MAC addresses per port
Limitation of MAC addresses per port
MAC-based white/black list per port

Data Transmission

Streamlined ETHERNET 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

IP-Based VLAN

Routing of data packets between VLANs via IP address
Communication from one participant to two or more VLANs
Economic connection of networks to higher-level routers
Prioritization of data packets via IP address

MAC-Based VLAN

Assignment of data packets to a VLAN via MAC address
Prioritization of data packets via MAC address

Performance

Streamlined ETHERNET Networks

Network Optimization

LACP link aggregation

Merge multiple data connections into a single logical link:

Increase transmission rate
Link redundancy

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
Limitating broadcast and multicast data flows (packets/time)

Customer Applications: Industrial Switches

The Energy-Efficient Porcelain Factory

The porcelain manufacturer BHS tabletop AG has invested in a new combined heat and power plant in Schönwald, partially modernized its heat distribution system and installed a central control system with increased operational reliability. This saves the company a lot of energy.
