ETH-4NAT is suitable for all network ports PLC (TCP/UDP protocol) network communication and data acquisition, and has the functions of cross-network segment and transparent transmission. ETH-4NAT supports NAT conversion of 4 network port PLCs at the same time; if multiple devices in the workshop have different IP addresses, they can be unified into the IP addresses of the same network segment for data collection. The module integrates WiFi function, supports AP mode, STA mode and AP+STA mode, which is very convenient to build WiFi network, PLC programming, data acquisition and cross-network segment access directly through WiFi.
ETH-4NAT has three physical ports, LAN1 port is four RJ45 ports, with switch function, it is mainly used to connect PLC; LAN2 port is single port RJ45, which is mainly used for the connection of upper computer. The WiFi interface is an external antenna, which is used to connect to the upper computer.
ETH-4NAT can realize the address translation function of 4-way NAT at the same time, which can map the PLC device connected to LAN1 to any IP address of the LAN2 port or WiFi interface, which solves the problem that the field device cannot modify the IP address.
In short, it has the powerful functions of switches, cross-network segments, multiple NAT port mappings, multiple clients, and WiFi connections.
ETH-4NAT function
- Installed on a 35mm guide rail, LAN1 is a four-port RJ45 with switch function, and this port is connected to PLC; LAN2 is a single-port RJ45, which can be connected to the host computer; WiFi external high-gain antenna can be connected to the host computer; ETH- 4NAT needs an external 24VDC power supply;
- Support NAT mapping and IP address access across network segments for 4 PLCs;
- Integrated WiFi function, support AP mode, STA mode and AP+STA mode;
- PLC programming and data acquisition can be performed through WiFi;
- Integrated WEB server, device parameters and operation diagnosis can be set through the webpage; it can also be configured through the BCDevice tool; it can be configured arbitrarily from LAN1, LAN2 or WiFi;
- The host computer can access the devices connected to the LAN1 interface through LAN2 or WiFi, and can convert IP across network segments;
- It can support up to 32 host computer connections;
- Support firmware update on the user side through Ethernet, one purchase, permanent upgrade.
