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.
Шаг 1: Confirm Mounting Method
Determine the product series directly:
- DIN Rail Mount (Most control cabinets & automation production lines)
Choose: RS20 / RS30 / RS40 compact series
- 19-inch Rack Mount (Central control room & power distribution core cabinet)
Choose: MACH100 / MACH4000 rack-mounted series
- Outdoor Wall Mount / Cabinet-Free (Outdoor base station, tunnel, pumping station)
Choose: OCTOPUS IP65/IP67 waterproof series
- Panel Embedded Mount (Built-in equipment)
Choose: EAGLE / dedicated panel type
Шаг 2: Confirm Port Quantity, Тип порта & Скорость
Total Port Quantity
Count PLC, ЧМИ, instrument and camera quantities on site, reserve 20% redundancy.
Общий: 4-port / 8-port / 16-port / 24-port.
Тип порта (Core Selection Point)
RJ45 Copper Port: Indoor short distance ≤100m, standard network cable
Оптоволоконный порт: Большое расстояние & сильная защита от помех
Multi-mode (MM): ≤2km, intra-factory & building interconnection, бюджетный
Single-mode (СМ): ≥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.
Скорость
Ordinary PLC, инструмент & мониторинг: 10/100M Fast Ethernet is sufficient
Machine vision, big data, multi-camera & core aggregation: Full Gigabit
Шаг 3: Select Management Mode
Three grades based on network complexity:
- Unmanaged
Функции: Подключи и работай, zero configuration
Приложение: Single device, simple production line, no network partition or ring redundancy
Суффикс: U
- Managed Lite
Supports VLAN, QoS, port rate limiting, basic ring network
Приложение: Multi-workshop partition, simple isolation & basic redundancy
- Full Managed
Supports HIPER-Ring, MRP, RSTP, IGMP multicast, network security, port mirroring, сигнализация неисправности
Приложение: Власть, железнодорожный транзит, smart factory, ring topology, high reliability non-stop network
Шаг 4: Select Operating Temperature Grade
- Standard Temperature: 0℃~+60℃
Приложение: Air-conditioned central control room, constant temperature cabinet
- Wide Temperature: -40℃ ~ +70 ℃
Приложение: 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.
Шаг 5: Power Specification & Redundancy
- Напряжение: Industrial standard 24VDC, some support 12~48VDC wide voltage
- Dual Power Redundancy: Mandatory for key production sections, power and rail transit; avoids network outage from single power failure
- Защита: Reverse polarity protection & surge immunity; prioritize industrial EMC protection for harsh power environments
Шаг 6: Network Redundancy & Special Application Requirements
- Ring Network Self-healing (Network remains online when one cable breaks)
Must choose managed switches supporting HIPER-Ring / MRP / RSTP
- Network segmentation & device isolation → Require VLAN
- Multiple cameras & streaming media → Require IGMP multicast
- Industrial security & unauthorized access prevention → Require port security & MAC binding
Шаг 7: Класс защиты & Industry Certification
- Класс защиты
Cabinet installation: Standard IP20
Outdoor, пыльный & humid site: IP65/IP67 OCTOPUS series
- Industry-Specific Certification
Power industry: Mandatory IEC 61850-3
Железнодорожный транзит: В 50155
Морской & offshore: Ship classification certification
Explosion-proof chemical industry: Explosion-proof grade certification
Hirschmann Main Series Positioning
| Ряд | Позиционирование | Сценарий применения |
| RS20 | Entry-level compact | Small production line, ordinary control cabinet, mostly unmanaged, conventional budget |
| RS30 | Mid-range mainstream | Gigabit SFP, basic management, small & medium factory ring network, экономически эффективный |
| RS40 | High-end industrial | Full Gigabit, full-featured management, power/rail transit/high-end smart factory |
| MACH100/4000 | Rack-mounted core | 19-inch cabinet machine room, plant-level core aggregation switch |
| OCTOPUS | Outdoor waterproof | Outdoor, tunnel, pumping station, cabinet-free on-site installation |
Industry Recommended Selection
- General Automation Production Line / Workshop
8/16-port RS20 wide-temperature unmanaged — cost-effective and sufficient
- Multi-workshop Ring Network / Smart Factory
RS30 Gigabit SFP managed with ring network support
- Power Substation / PV & Wind Power
RS40 wide-temperature + IEC61850 certification + dual power redundancy
- Железнодорожный транзит / Tunnel Outdoor
OCTOPUS IP67 waterproof + wide temperature + rail transit certification
- Central Control Room Core Aggregation
MACH rack-mounted full Gigabit
Common Selection Pitfalls
- Do not blindly choose full Gigabit; 100M is enough for ordinary PLC and wastes budget.
- Avoid standard temperature models for industrial sites; cabinet overheating easily occurs in summer.
- Use single-mode fiber ports for long-distance cross-plant connection; do not use network cables for long-distance laying.
- Ring topology must use managed switches; unmanaged switches cannot implement ring redundancy.
- Key equipment must adopt dual power redundancy to prevent entire network paralysis from single power failure.
