ETS-7200 Secure Ethernet I/O Modules The ETS-7200 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-7200 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.

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-7200 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 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.

 

Equipped with robust defense mechanisms, the ETS-7200 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.

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.

The ETS-7200 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.

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.

Supporting 802.1Q and 802.1p priority tagging, the ETS-7200 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.

 

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.

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.
