NAT switches

The 2000 series NAT switch

Switches with NAT routing function combine switching and routing in a single DIN rail device.

Cost-effective integration in higher-level networks – With virtual addressing (NAT)

If identical machines are operated in parallel in a network, each machine must be configured individually. This is the only way to integrate them into the higher-level communication network. Various NAT mechanisms enable you to operate entire production cells with the same IP address space, without having to configure the machines individually.

In the image gallery, we present various NAT mechanisms that are supported by our NAT switches.

Very flexible

NAT switch with two WAN ports and six LAN ports  

The ports of the NAT switch can be freely used as LAN or WAN ports

The FL NAT 2000 offers a high degree of flexibility, as each of its 8 ports can be freely assigned as LAN or WAN ports. This means that you can use the FL NAT 2000 as a simple NAT switch with one WAN port and seven LAN ports. There is no need for an additional switch in the system.

Alternatively, you can use the NAT switch to connect a machine to multiple higher-level networks, such as production and diagnostics networks. You can choose from various NAT mechanisms: 1:1 NAT, virtual NAT, IP masquerading, and port forwarding.

Redundancy in the LAN and WAN

FL NAT in the RSTP and MRP ring  

The FL NAT 2000 supports RSTP and MRP redundancy mechanisms

In order to ensure a high degree of reliability both within the system and when connecting to higher-level networks, FL NAT 2000 switches support redundancy mechanisms on the LAN and WAN side.

For redundant connection to higher-level WAN interfaces, you can integrate the FL NAT 2000 into an RSTP ring with two WAN ports.

On the LAN side, you can use both RSTP and MRP as the master or client to redundantly connect parts of a machine to the NAT switch.

PROFINET support in the LAN

NAT switches support PROFINET functions

On the LAN side, the FL NAT 2200 and the FL NAT 2300 offer full PROFINET integration:

  • Integration in PROFINET control environments, e.g., TIA or PC Worx
  • MRP support for increased availability
  • LLDP for topology detection
  • Hardware-based PROFINET prioritization
  • Extended diagnostics for PROFINET
