IoT HMI
Overview
Samkoon SK Series IoT Human-Machine Interface (IoT HMI) is engineered for edge-computing data aggregation, multi-protocol industrial translation, and secure cloud telemetry architecture. Utilizing an innovative modular snap-on IoT expansion framework, this platform bridges standard on-site machinery directly to centralized Scada and cloud infrastructures via integrated dual-band Wi-Fi, high-capacity 4G LTE cellular modules, or gigabit Ethernet physical links. Built to eliminate localized field commissioning limits, it delivers real-time remote configuration windows while operating reliably under harsh high-interference manufacturing workshop floors.
Product Features
Secure VNC & Remote Edge Control
Integrates native VNC server capabilities, enabling plant engineers to mirror, view, and override the HMI display terminal execution environment securely from any authorized PC, iOS, or Android mobile device. Real-time frame synchronization facilitates instant off-site troubleshooting.
Cloud Platform & Multi-Brand PLC Pass-Through
Fully optimized for Display Control Cloud 3.0 ecosystems. The embedded firmware framework natively executes Remote PLC Program Upload/Download (Pass-Through Routing), allowing remote ladder logic modifications for mainstream peripheral PLCs without requiring on-site engineering deployments.
Comprehensive Protocols & Physical Port Matrices
Equipped with isolated RS232, RS422, and dual RS485 channels running concurrently with hardware-level optical isolation. The system firmware supports native protocol mapping for Modbus-RTU/TCP, MQTT edge nodes, and mainstream industrial communication controllers to remove register-matching friction.
Modular Plug-and-Play Cellular Extensions
Features unique hardware-latching backplane slots supporting hot-swappable Samkoon IoT modules. System builders can transition between standalone local Ethernet setups and global 4G/Wi-Fi remote networking clusters instantly without altering cabinet footprint sizing layouts.
