5. Selection Guidelines & Alternative Solutions

Key Selection Considerations

1. Port Type: Select uplink port type (single/multi-mode fiber, RJ45) according to network topology; single-mode for long distance (>2km), multi-mode for short distance (<2km).
2. Software Function: Unmanaged (U) for simple plug-and-play scenarios; Managed (E/P) for complex networks requiring VLAN, QoS, ring redundancy.
3. Temperature Range: Wide-temperature model (H) for outdoor, high-temperature workshop and harsh environments; standard model for general indoor industrial sites.
4. Power Requirement: Confirm whether dual power redundancy is needed to enhance system reliability.
5. Certification: Select products compliant with IEC 61850-3, UL 508, ISA 12.12.01 based on regional and industry standards.

How to Select Hirschmann Industrial Ethernet Switches According to Actual Requirements

Below is a standardized 7-step selection process applicable to engineering projects, together with series positioning, industry matching and common selection pitfalls.

Step 1: Confirm Mounting Method

Determine the product series directly:

1. DIN Rail Mount (Most control cabinets & automation production lines)

Choose: RS20 / RS30 / RS40 compact series

2. 19-inch Rack Mount (Central control room & power distribution core cabinet)

Choose: MACH100 / MACH4000 rack-mounted series

3. Outdoor Wall Mount / Cabinet-Free (Outdoor base station, tunnel, pumping station)

Choose: OCTOPUS IP65/IP67 waterproof series

4. Panel Embedded Mount (Built-in equipment)

Choose: EAGLE / dedicated panel type

Step 2: Confirm Port Quantity, Port Type & Speed

Total Port Quantity

Count PLC, HMI, instrument and camera quantities on site, reserve 20% redundancy.

Common: 4-port / 8-port / 16-port / 24-port.

Port Type (Core Selection Point)

RJ45 Copper Port: Indoor short distance ≤100m, standard network cable

Fiber Port: Long distance & strong anti-interference

Multi-mode (MM): ≤2km, intra-factory & building interconnection, low cost

Single-mode (SM): ≥5~15km, cross-plant road, power remote transmission, outdoor

SFP Slot: Hot-pluggable Gigabit/100M fiber module, flexible expansion; recommended for mid-to-high-end projects.

Speed

Ordinary PLC, instrument & monitoring: 10/100M Fast Ethernet is sufficient

Machine vision, big data, multi-camera & core aggregation: Full Gigabit

Step 3: Select Management Mode

Three grades based on network complexity:

1. Unmanaged

Features: Plug-and-play, zero configuration

Application: Single device, simple production line, no network partition or ring redundancy

Suffix: U

2. Managed Lite

Supports VLAN, QoS, port rate limiting, basic ring network

Application: Multi-workshop partition, simple isolation & basic redundancy

3. Full Managed

Supports HIPER-Ring, MRP, RSTP, IGMP multicast, network security, port mirroring, fault alarm

Application: Power, rail transit, smart factory, ring topology, high reliability non-stop network

Step 4: Select Operating Temperature Grade

1. Standard Temperature: 0℃~+60℃

Application: Air-conditioned central control room, constant temperature cabinet

2. Wide Temperature: -40℃ ~ +70℃

Application: High-temperature workshop, outdoor, non-air-conditioned cabinet, cold northern & hot southern environments

Industrial sites are recommended to choose wide-temperature models for higher fault tolerance.

Step 5: Power Specification & Redundancy

1. Voltage: Industrial standard 24VDC, some support 12~48VDC wide voltage
2. Dual Power Redundancy: Mandatory for key production sections, power and rail transit; avoids network outage from single power failure
3. Protection: Reverse polarity protection & surge immunity; prioritize industrial EMC protection for harsh power environments

Step 6: Network Redundancy & Special Application Requirements

1. Ring Network Self-healing (Network remains online when one cable breaks)

Must choose managed switches supporting HIPER-Ring / MRP / RSTP

2. Network segmentation & device isolation → Require VLAN
3. Multiple cameras & streaming media → Require IGMP multicast
4. Industrial security & unauthorized access prevention → Require port security & MAC binding

Step 7: Protection Class & Industry Certification

1. Protection Class

Cabinet installation: Standard IP20

Outdoor, dusty & humid site: IP65/IP67 OCTOPUS series

2. Industry-Specific Certification

Power industry: Mandatory IEC 61850-3

Rail transit: EN 50155

Marine & offshore: Ship classification certification

Explosion-proof chemical industry: Explosion-proof grade certification

Hirschmann Main Series Positioning

Industry Recommended Selection

1. General Automation Production Line / Workshop

8/16-port RS20 wide-temperature unmanaged — cost-effective and sufficient

2. Multi-workshop Ring Network / Smart Factory

RS30 Gigabit SFP managed with ring network support

3. Power Substation / PV & Wind Power

RS40 wide-temperature + IEC61850 certification + dual power redundancy

4. Rail Transit / Tunnel Outdoor

OCTOPUS IP67 waterproof + wide temperature + rail transit certification

5. Central Control Room Core Aggregation

MACH rack-mounted full Gigabit

Common Selection Pitfalls

1. Do not blindly choose full Gigabit; 100M is enough for ordinary PLC and wastes budget.
2. Avoid standard temperature models for industrial sites; cabinet overheating easily occurs in summer.
3. Use single-mode fiber ports for long-distance cross-plant connection; do not use network cables for long-distance laying.
4. Ring topology must use managed switches; unmanaged switches cannot implement ring redundancy.
5. Key equipment must adopt dual power redundancy to prevent entire network paralysis from single power failure.
