PAIN POINTS

Industry Pain Points

🔌

Difficult Device Protocol Access

Field devices speak disparate, mutually incompatible protocols such as Modbus, IEC 104, OPC, BACnet, and S7. Traditional gateways support only a few protocols, forcing redundant acquisition software development on every project.

☁️

Unreliable Cloud Data

Pure-cloud architectures depend heavily on network connectivity: when 4G signals weaken or fiber cuts occur, data is lost and critical alarms fail to trigger in time.

⏱️

Slow Control Response

Cloud-edge-device links add tens of milliseconds to seconds of latency, unable to serve fast control scenarios that demand millisecond response (microgrid on/off-grid switching, production line emergency stop).

🧩

Expensive System Expansion

Traditional PLC plus acquisition gateway means two separate systems: doubled hardware and software investment, complex cross-platform integration, and brand-locked I/O expansion that drives up selection costs.

CR series I/O covers digital DI/DO, analog AI/AO, PT100/NTC thermal resistance, relay output, and other module types, cascaded over RS485 or CAN bus to expand a single gateway to up to 512 points.

🔒

Capability 5

Encryption & VPN Tunnels

Multiple VPN tunnels (IPsec/L2TP/OpenVPN), MQTT TLS encrypted transmission, X.509 certificate mutual authentication, and username/password authentication form three tiers of protection; data stays encrypted all the way to the cloud, meeting MLPS compliance requirements.

🛠️

FAQ

Which protocols do your edge computing gateways support? How long does it take to add a new protocol?

CW series gateways come with 100+ built-in industrial protocols covering mainstream PLCs (Siemens S7 series, Mitsubishi MC/FINS, Omron FINS, Delta, Inovance, Xinje, etc.), instruments and meters (Modbus RTU/TCP, DLT645, CJ/T188, GB/T 19582, etc.), building automation (BACnet MS/TP, BACnet/IP, KNX, LonWorks), the power industry (IEC 104, IEC 61850 MMS/GOOSE/SV, Modbus TCP), and general IT (MQTT, OPC UA, HTTP RESTful, WebSocket). Custom new protocols typically take 3-5 business days to develop and debug on the SDK.

How do CC series PLCs compare with Siemens and Mitsubishi in compatibility and reliability?

CC series PLCs follow the IEC 61131-3 international standard and support four programming languages: LD ladder diagram, FBD function block diagram, SFC sequential function chart, and ST structured text. Programming habits closely match Siemens S7-200 SMART and Mitsubishi FX series, so engineers need no retraining. For stability, CC PLCs are built with industrial-grade components, operate across -40°C to +75°C, pass EMC Class A certification for interference immunity, and deliver an MTBF greater than 50,000 hours, with volume-proven deployments in demanding sites such as a major port and a major grid operator.

How do 4G gateways ensure no data loss in areas with poor signal?

The FEXLINK CW edge computing gateway is engineered with three layers of reliability assurance: ① local offline caching—built-in 8GB eMMC storage buffers more than 3 months of data at default sampling frequencies; ② breakpoint resume—after the network recovers, uploads continue from the exact breakpoint, with no duplication or omission; ③ multi-link backup—high-end CW models support automatic dual-4G-SIM switching plus wired Ethernet and Wi-Fi backup, failing over to a standby link whenever any single link fails. For extreme no-signal scenarios, LoRa or BeiDou short-message transmission modules can be added.

Can customers run their own algorithms and programs on the gateway?

Absolutely. The CW gateway opens the complete Linux user space and supports: ① Docker containerized deployment—customers package custom applications as Docker images and push them remotely with one click via the platform; ② Python/C++/Node.js SDKs—complete API wrappers for reading and writing locally acquired data and sending control commands; ③ edge AI acceleration—high-end models come with an NPU neural network accelerator supporting TensorFlow Lite, ONNX Runtime, and other edge AI inference frameworks, with inference speeds up to 5 TOPS.

What does OEM customization cover? What is the minimum order quantity?

FEXLINK provides equipment vendors and system integrators with a full suite of OEM/ODM customization services: ① hardware customization—interface count and types, mounting methods, mechanical design, and enclosure color/silkscreen; ② firmware customization—boot logo, default configuration, preloaded protocols, and brand information; ③ platform customization—dedicated OEM domain, branded interface, and white-label API integration. Hardware customization MOQ typically starts at 100 units, pure firmware/branding white-label MOQ starts at 50 units, and special projects can be negotiated case by case.
