iKAN Cybersecurity LED Display

Administrators only need to connect to the iKAN message display through a web browser with HTTPS encrypted communication to ensure the security of the configuration process. They can configure message content and update the display directly through the web interface.
No software installation or programming is required. Additional iKAN displays can also be added flexibly as needed, eliminating the limitations associated with dedicated control software.

The iKAN message display can store up to 128 text messages with configurable message priorities, meeting the message display requirements of a wide variety of applications.
Once the required messages have been edited and saved through the web interface, there is no need to repeatedly re-edit them. PLC/SCADA systems can control in real time which messages are displayed or hidden, as well as the text color.

Messages can be assigned a higher priority. Once activated, high-priority messages will be displayed before lower-priority messages.
Users can use a smartphone to determine whether a specific message should be displayed. Remote host applications can also control which messages should be displayed with priority when an emergency occurs.

Modbus is an industry-standard communication protocol in industrial automation and is one of the most widely used methods for communication between industrial electronic devices.
To meet modern industrial cybersecurity requirements, the iKAN further supports Modbus TLS for encrypted communication. It also supports EtherNet/IP, which is widely adopted by mainstream PLCs, and provides EIP Security encrypted communication capabilities to ensure secure and reliable data exchange across industrial control networks.

When industrial control equipment uses the Modbus protocol to transmit data, physical values such as pressure, temperature, and weight are typically converted into 16-bit integer values.
After receiving the data, the control host must perform calculations to convert the integer values back into the corresponding physical values. Different devices may use different conversion methods depending on their requirements.
The iKAN message display includes a built-in data conversion function that allows users to define different conversion parameters for each integer value. When data from various devices is written to the iKAN, the device automatically converts the integer values and displays the calculated results.

In addition to integer data conversion, the iKAN message display allows users to convert the 0/1 status values of switches, relays, and various digital channels into highly readable and easy-to-understand descriptive text.

To seamlessly integrate with cloud and IoT architectures, the iKAN features built-in MQTT functionality, enabling field variables and messages to be efficiently published to or subscribed from an MQTT Broker using a lightweight communication mechanism.
It supports TLS transport encryption and mutual certificate authentication, effectively preventing plaintext eavesdropping and providing more secure synchronization of information displays and dashboards across multiple sites.

For IT administrators and system maintenance personnel, the iKAN provides a modern, standards-based Redfish HTTP JSON API. Access to protected resources requires authentication and authorization, helping prevent unauthorized modifications.
When used with the dedicated mobile app, on-site personnel can quickly discover devices on the same network segment via mDNS and securely read or write display content and verify data values through a user-friendly graphical interface, significantly simplifying system operation and maintenance.
