ETS-2200 Secure Ethernet I/O Modules
 
The ETS-2200 modules support RESTful API and Industrial IoT communication protocols, including Modbus and MQTT Client. These modules are designed with comprehensive cybersecurity mechanisms, such as support for SSL/TLS certificates for encryption, to ensure that sensor data is transmitted securely and protected from unauthorized access.

 
The ETS-2200 provides an IP address filter function with an allow-list, blocking all other access, thereby reducing the risk of unauthorized access and enhancing security. The Netstat feature provides real-time monitoring of connection status for listening TCP ports and connected clients. Equipped with various types of I/O, the module also has a built-in web server (HTTP/HTTPS) that allows users to configure, monitor, and control I/O directly via a web browser, making it ideal for remote control applications.

Features

SSL/TLS Encryption for Ensured Security and Data Protection

SSL/TLS uses certificates and a public-key infrastructure (PKI) to authenticate the identities of both the server and the client, ensuring a secure connection and protecting against man-in-the-middle (MITM) attacks. All data transmitted is encrypted, preventing unauthorized access or modification. The ETS-2200 modules support SSL/TLS, offering continuous security from initial configuration to online operation. They provide comprehensive protection for communications, ensuring that data remains private, intact, and authentic, making the module ideal for building secure systems.

Support MQTT and Modbus for Flexible System Integration

Support both the MQTT client (compliant with the MQTT V3.1.1 protocol) and the widely used Modbus TCP protocol for industrial automation. These protocols work simultaneously, providing flexibility and simplifying system integration. This enables seamless remote monitoring and control via SCADA systems or IIoT platforms. By incorporating SSL/TLS protocols into both MQTT and Modbus TCP communications, we enhance security, ensuring that data transmitted across networks is protected against unauthorized access and potential cyber threats.

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

Equipped with robust defense mechanisms, the ETS-2200 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.

 

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.

  

mDNS Hostname Resolution for Easy Connection

The ETS-2200 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.

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.

802.1Q and 802.1p Tagging for Prioritized Network Transmission

Supporting 802.1Q and 802.1p priority tagging, the ETS-2200 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.

Ethernet Daisy-Chain Cabling with LAN Bypass

Include a 2-port Ethernet switch that supports a daisy-chain network topology. This topology simplifies wiring, reduces maintenance complexity and lowers both wiring and maintenance costs, while increasing network scalability. In addition, the module is equipped with a LAN bypass function that ensures stable Ethernet communication. If a module loses power, this function is automatically activated to maintain seamless network connectivity.

Built-in Various I/O Functions

Support various I/O types, including optically isolated digital inputs, power relays, PhotoMOS relays, and open-collector outputs. The I/O Pair-Connection function establishes mirrored input-to-output pairs over Ethernet, enabling bidirectional data exchange between the local module and remote devices. Once configured, the module automatically transfers data between their respective paired I/O channels via Modbus TCP.

Fast Boot (< 5 Seconds) for Immediate Operation

The module powers up and becomes fully operational in less than 5 seconds, ensuring immediate system availability. This rapid startup enhances productivity, reduces delays in critical applications, and improves workflow efficiency. By enabling a quick reboot after power cycles or unexpected shutdowns, it minimizes downtime and enhances the overall user experience.

 

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.
 

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.
