Features

1.Multiple Security Protection Mechanisms

A built-in HTTP/HTTPS web server, with HTTPS providing a secure web service interface, allows users to configure module configuration, control output channels, and monitor module connections and I/O status through a web interface or RESTful API. This process is simple and fast, and requires no additional software installation. The ETS-8000 series supports Industrial IoT communication protocols such as Modbus, OPC UA Server/Client, MQTT Client, and LwM2M Client, and offers the option to enable SSL/TLS certificates and encryption. This encryption ensures that real-time sensor data is encrypted during transmission, preventing unauthorized access. Furthermore, the ETS-8000 series features an IP address filter, allowing users to allow or block access to specific IP addresses. The Netstat function can be used to view listening TCP ports and connected clients, helping to monitor the ETS-8000's real-time connection status.

2. Rich I/O expansion

The ETS-8000 series provides 4/8 I/O slots suitable for I-8K and I-87K series I/O modules for Ethernet expansion.

I-8K/I-87K Series (High Profile)

3. Denial-of-Service (DoS/DDoS) Attack Defense

Equipped with robust defense mechanisms, the ETS-8000 protects against DoS and DDoS attacks. It actively regulates network traffic to reduce the impact of large volumes of abnormal network packets on Ethernet operations, ensuring that the module remains functional and reliable.

4. IPv4/IPv6 Dual-Protocol for Flexible Network Configuration

The module incorporates dual-stack technology for effective communication over both IPv4 and IPv6 networks. Users can operate without additional configuration because the system automatically evaluates packet sources to determine the appropriate network protocol. With SLAAC (Stateless Address Autoconfiguration), the module automatically requests IP information from the router, eliminating the need to manually set complex IPv6 addresses and ensuring seamless connectivity.

5.mDNS Hostname Resolution for Easy Connection

The ETS-8000 modules support the mDNS (Multicast DNS) protocol, allowing easy-to-remember domain names (e.g., EthernetIO.local) for local network communication with compatible browsers and software. Whether the module operates with static or dynamic IP addresses, users can maintain communication through the fixed mDNS domain name, helping to prevent problems associated with IP address changes.

6.Rule Logic Engine for Streamlined Edge Control

Built-in logic engine that supports IF-THEN-ELSE rules to make decisions with physical I/O and software points. This capability enables stable and efficient execution of automated monitoring tasks. The logic engine also supports encrypted and unencrypted e-mail notifications to efficiently notify relevant personnel when specific events occur.

7.802.1Q and 802.1p Tagging for Prioritized Network Transmission

Supporting 802.1Q and 802.1p priority tagging, the ETS-8000 module tags data frames on selected network protocols for use with 802.1Q compliant switches. In environments with limited network bandwidth, this configuration effectively preserves network resources for time sensitive network communication, ensuring low-latency and high-reliability transmission.

8.Ethernet Daisy-Chain Cabling with LAN Bypass

The ETS-8000 series modules feature a built-in dual-channel Ethernet switch, supporting a daisy-chain topology. The benefits of using a daisy-chain topology include simplifying cabling and maintenance complexity, effectively reducing cabling and maintenance costs, and improving network scalability. Furthermore, the ETS-8000 features a LAN Bypass function to ensure Ethernet communication stability. If any ETS-8000 module loses power, this function automatically activates to maintain network connectivity.

10. Dual Watchdog with Power-on and Safe Values

To ensure system reliability, stability, and continuous operation, this module incorporates a Dual Watchdog design. The hardware watchdog automatically resets the MCU if it detects a module freeze, preventing it from stopping working. This reset loads the AO/DO values according to user-defined power-on settings. The software watchdog monitors communication activity between the host controller and the module. If the watchdog timeout occurs, the module switches its outputs to predefined safe values to prevent incorrect operation.

11. Seamless Device Interaction via a RESTful API

Supports reading and writing of I/O and virtual points over HTTP, with HTTPS ensuring secure, encrypted communications. This feature enables secure data transmission, facilitates remote access for seamless device interaction, and offers cross-platform compatibility. Additionally, it provides scalability for system growth and simplifies integration.
