NE870 是一款工业路由器，也充当防火墙。路由器/防火墙可用于将系统划分为网络区域和安全区域。NE870主要用于分离客户端/服务器网络和控制网络，分离不同的控制和安全网络，以及在RNRP网络之间创建RNRP隧道区域。

IEC 62443 中描述了安全分区的概念。简而言之，安全分区是一种将系统划分为具有不同安全级别的区域的方法。通过实施安全对策的组合来遵守安全级别。将系统划分为符合不同安全级别的安全区域可能是有意义的，原因可能是系统不同部分的风险不同。另一个可能是潜在事件的影响各不相同。

NE870 支持 RNRP（冗余网络路由协议），使 800xA 能够拥有两个物理上独立的网络，从而避免单点故障。

The NE870 is an industrial router that also acts as a firewall. Routers/firewalls can be used to divide the system into network zones and security zones. The NE870 is primarily used to separate client/server networks from control networks, separate different control and security networks, and create RNRP tunnel zones between RNRP networks.

The concept of secure partitions is described in IEC 62443. In a nutshell, security partitioning is a way of dividing a system into zones with different levels of security. Compliance with security levels by implementing a combination of security countermeasures. It may make sense to divide the system into security zones that conform to different security levels, possibly because the risks are different for different parts of the system. Another possibility is that the impact of potential events varies.

The NE870 supports RNRP (Redundant Network Routing Protocol), which enables 800xA to have two physically independent networks, thereby avoiding a single point of failure.
