簡介

NPort® S8458系列集合了串口設備聯網服務器和網管型交換機于一體，具有4個光纖口，4個以太網口和4個RS-232/422/485串口，讓您可以輕松安裝、管理和維護您的產品。NPort® S8458具有串口聯網和交換機的功能，可大大節(jié)省使用空間，降低功耗和成本，因為您無需再單獨購買交換機和串口設備聯網服務器。

具備NPort®系列產品的功能
NPort® S8458系列支持NPort®系列串口設備聯網服務器的所有功能。您最多可將4臺串口設備通過8個以太網口進行網絡連接，而只需做一些基本的配置要求。此外，串口和網口之間的數據傳輸是雙向的。

支持網管型交換機功能
NPort® S8458系列內建了網管型交換機功能，支持QoS，IGMP-snooping/GMRP，VLAN，Port Trunking，SNMPv1/v2c/v3和IEEE 802.1X，讓您可以任意使用。在網絡冗余方面，Moxa的Turbo Ring和Turbo Chain技術（自愈時間<20ms）或RSTP/STP（IEEE 802.1w/D），可以讓您的工業(yè)以太網絡冗余更具冗余性，更為可靠穩(wěn)定。

設備層的環(huán)網冗余
工業(yè)自動化中，設備層的通信網絡是非常關鍵的，因為它們用來監(jiān)控設備的運行。通信的可靠性取決于設備層的環(huán)網冗余，可支持快速的網絡故障檢測和重新配置，適用于最嚴苛的控制應用。NPort® S8458系列集成了NPort®系列串口設備聯網服務器和交換機的功能，可同時連接串口設備和網絡設備。此外，NPort® S8458還支持STP/RSTP標準、Moxa的Turbo Ring或Turbo Chain網絡冗余協議。這種一體化的設計可簡化您的網絡，并提升網絡的可靠性。
