Overview & Background
Beijing YiLink Technology presents a fully autonomous industrial automation PLC system solution, engineered to benchmark against industry leaders like Inovance and Siemens. Powered by the proprietary real-time operating system kernel (yiOS), the solution completely eliminates reliance on foreign proprietary black boxes. At its core, the modular YC200/YC201 PLC CPU interconnects via a 1 Mbps high-speed CAN backplane bus with the full spectrum of YM200 industrial expansion modules: 16DI/16DO optocoupler-isolated digital units, European-standard sourcing PNP modules, 4-channel bistable pulse-latching relays (zero steady-state power with non-volatile mechanical state retention during outages), and 4-channel high-precision PT100/PT1000 RTD temperature modules. Crucially, all YM modules support dual operation modes: high-speed local backplane expansion or standalone Remote I/O over standard CANopen and Modbus fieldbuses. Complemented by an installation-free cloud-native Web IDE, terminal-level wiring simulation (yiSim), and AI-assisted code generation, the platform provides machine builders, automated assembly lines, and process industries with a cost-effective, dependable, and future-proof automation foundation.
Critical Bottlenecks in Traditional Automation & Imported PLCs
- Vendor lock-in and foreign dependencies: Core PLC execution runtimes, compilers, and bus stacks rely heavily on imported software, risking supply disruption and costly recurring licenses;
- Rigid and expensive I/O expansions: Expansion modules from legacy brands depend on proprietary closed backplanes, preventing flexible reuse as generic distributed Remote I/O units;
- Heavy and cumbersome desktop IDEs: Legacy programming suites require tens of gigabytes of disk space, specific Windows revisions, and hardware dongles that hinder collaborative development;
- Loss of critical actuator states during power outages: Standard relays release when power drops, failing to preserve pre-outage valve and motor statuses and risking process failure;
- Severe electromagnetic noise in harsh industrial environments: High-power inverters, welding arcs, and inductive kickbacks trigger digital false alarms without robust sourcing PNP drivers and undervoltage protection.
Core Advantages & Technical Highlights
100% Proprietary Autonomous Industrial Control FoundationIn-house embedded real-time OS (yiOS), IEC 61131-3 five-language runtime engine, web compilation pipeline, and hardware schematics deliver complete autonomy without hidden vulnerabilities.
Fully Aligned with International Industrial StandardsComplete support for Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), Sequential Function Chart (SFC), and Instruction List (IL). Ladder networks mirror Siemens, while device trees align with CODESYS and Inovance paradigms.
Dual Operating Modes: Backplane Slave & Standalone Remote I/OYM200 digital, sourcing PNP, latching relay, and RTD modules function both as local backplane expansion units and as standalone Remote I/O over CANopen and Modbus.
Zero-Power Mechanical State Memory & Rugged HardwareProprietary YM200-04M 4-channel latching relay module retains contact positions permanently during power loss using 10ms bidirectional pulse excitation; YM201-16I16OP features sourcing PNP drivers with 24V undervoltage detection.
Zero-Install Web IDE with yiSim Circuit SimulationProgram and monitor directly from modern browsers. Built-in wiring-level schematic simulation verifies electrical rules and simulates hardware-in-the-loop behavior, cutting commissioning risks by 70%.
AI Engineering Assistant & Verified Function Block MarketplaceBuilt-in industrial LLM generates and refines Ladder and ST logic from natural language prompts; integrated marketplace offers 85+ pre-verified industrial function blocks (FBs) for instant project reuse.
Autonomous Industrial Automation System & Bus Topology
The system establishes the modular YC200 CPU as the local automation hub, interfacing upward with supervisory SCADA over industrial Ethernet and downward with digital, PNP, latching relay, RTD modules, and HMI touch panels over high-speed CAN and fieldbuses.
