- Automatic seamless switchover and no data loss if any network cable fails
クイックトラブルシューティング
- Cannot access web page: Set PC IP to 192.168.1.xxx, disable firewall
- Serial communication failure: Switch RS232/485/422 mode in web page, verify baud rate and parity
- Virtual COM offline: Upgrade driver, set static device IP, avoid DHCP dynamic IP
- Dual LAN no switchover: Confirm redundancy is enabled; ensure two switches are not in the same loop
Advantech EKI-1526 Dual LAN Redundancy Full Configuration Guide
The EKI-1526 supports Master-Backup dual LAN redundancy with switchover time <1 2番. After enabling via Web UI, it automatically detects link faults and performs seamless failover to ensure uninterrupted industrial communication.
- Dual LAN Redundancy Working Principle
The EKI-1526 is equipped with two independent Ethernet ports (LAN1/LAN2) and independent MAC addresses:
Master Port: Carries all network traffic under normal operation
Backup Port: Monitors master port status in real time and takes over only when master port fails
Switchover Mechanism: Automatically switches to backup port upon LAN link down (cable disconnection / switch failure), switchover time <1 second with no data loss
Restore Mechanism: After master port recovers, configurable for auto switch back or remain on backup port
- Hardware Connection Preparation
Recommended Topologies (Avoid Single Point of Failure)
| Connection Mode | 説明 | アプリケーションシナリオ |
| Dual Switch Redundancy | LAN1 to Switch A, LAN2 to Switch B; both switches connect to core network | Critical production lines, unattended rooms; prevent single switch failure |
| Single Switch Dual Port | LAN1/LAN2 connect to different ports of the same switch | 予算は限られている; only protect against single port / cable failure |
| Dual Network Segmentation | LAN1 for production network, LAN2 for management network; サービス & management isolated | Security scenarios requiring network isolation |
Hardware Wiring Steps
- Power off the device, connect serial devices and power supply
- Connect LAN1/LAN2 to switches (dual switches recommended)
- 電源を入れる; check indicators: PWR steady on, both LAN LINK lights flashing normally
- Detailed Web Configuration Steps
- Basic Network Settings (必須)
- Set PC static IP: 192.168.1.× (same segment as device default)
- Browser access default IP: 192.168.1.1, login: `admin/admin`
- Go to Ethernet Configuration → Ethernet 1: Set master port IP, subnet mask, ゲートウェイ
- Go to Ethernet Configuration → Ethernet 2: Set backup port IP (same segment recommended, 例えば. 192.168.1.2), subnet mask, ゲートウェイ
- Click Save, device auto restarts (について 1 分)
- Enable Dual LAN Redundancy (Core Config)
- Log in Web UI again after reboot
- Enter Network → Redundancy
- Check Enable Dual LAN Redundancy
- Select Redundancy Mode:
Master-Backup (デフォルト): LAN1 as master, LAN2 as backup, auto failover upon fault
Load Balance: Both ports work simultaneously for traffic sharing (supported by partial firmware)
- Set Switch Back Mode:
自動: Automatically switch back to master after recovery (デフォルト)
マニュアル: Stay on backup port; manual switch required after master recovery
- Set Detection Interval: デフォルト 1 2番, adjustable 500ms~10s (1s recommended)
- Click Save, redundancy takes effect immediately
- Advanced Configuration (オプション)
| パラメータ | 推奨値 | 説明 |
| Heartbeat Packet | 有効にする | Enable heartbeat detection for higher fault accuracy |
| Heartbeat Interval | 100MS | Heartbeat sending interval; shorter = faster detection |
| Failover Count | 3 | Switch only after 3 consecutive failures to avoid false switching |
| Link Down Detection | 有効にする | Physical layer link detection (cable disconnection etc.) |
- Redundancy Function Test
- Link Fault Test
- Normal status: Web Status → Network Status shows LAN1 Active, LAN2 Standby
- Unplug LAN1 cable:
Device indicator: LAN1 off, LAN2 steady on
Web status updates: LAN2 becomes Active, switchover <1s
Verify serial communication via Virtual COM / Modbus TCP, no interruption
- Reconnect LAN1 cable:
Auto Mode: LAN1 resumes Active, LAN2 becomes Standby
Manual Mode: Remain on LAN2; manual switch required in Web UI
- Switch Failure Test
- Power off the switch connected to master port
- Device switches to backup port within 1 2番
- Restore master switch power and verify switchback works normally
- よくあるトラブルシューティング
| 故障現象 | 考えられる原因 | 解決 |
| Cannot enable redundancy | Firmware version too old | Upgrade to latest firmware from official website |
| Communication interrupted after switchover | Wrong backup port IP | Ensure master & backup ports same segment with consistent gateway |
| Frequent false switching | Detection interval too short | Extend interval to 2s, set Failover Count to 5 |
| No auto switch back after master recovery | Switch Back Mode set to Manual | Change to Auto or switch manually in Web |
| Both LAN ports down | Network configuration conflict | Check duplicate IP and subnet mask settings |
- Configuration Mnemonic
> Three steps for dual LAN redundancy: set IP first, enable redundancy second;
> Dual switches avoid single point; always verify failover after config.
- Hardware Selection: Critical sites choose dual switches; ordinary sites choose single switch dual port
- IP Planning: Master and backup ports recommended same network segment for easy management & switchover
- Mode Selection: Industrial control prioritizes Master-Backup; data collection can use Load Balance
- Switchback Policy: Unattended sites select Auto; manual intervention sites select Manual
- Test Validation: Perform link failover test after configuration to ensure reliable redundancy in actual faults
EKI-1526 dual LAN redundancy can be quickly configured via Web interface. The core is enabling redundancy and correctly setting master/backup IP and switchover policy. Cooperating with dual-switch topology, it effectively eliminates single-point faults in industrial networks and ensures high reliability of serial device communication. Full functional verification is recommended after deployment.
