Memory: Equipped with fixed storage areas, including digital inputs, analog inputs, flags, registers, counters, timers, etc.

Functional Features

Control Function: Based on ladder logic control, enabling various complex control logics.
Communication Function: As a communication interface module, it supports data communication with other devices and may have multiple communication protocol conversion functions, suitable for connecting different types of devices and systems (e.g., PLC, DCS, etc.).
Isolation Protection: Features isolation functions to protect circuits and personnel, break ground loops, and improve common-mode voltage and noise suppression performance, enhancing system stability and reliability.

Working PrincipleI. System Architecture and Core Components

Hardware Foundation

Main Control Unit: Integrates a high-performance microprocessor (e.g., ARM Cortex series), supporting real-time data processing and multi-task scheduling with a main frequency ≥400MHz to meet the high-speed response requirements of industrial control.
Communication Module: Built-in EtherCAT bus interface (100Mbps), Ethernet (10/100Mbps), and RS485/RS232 interfaces, supporting industrial protocols such as Modbus and CANopen to enable bidirectional communication with PLCs, sensors, and host computers.
Power Module: Powered by DC 24V (±10%), with reverse connection protection, overvoltage protection (OVP), and low-power design (power consumption

Functional Module Integration

I/O Interface: May include digital input/output (e.g., 16 DI/16 DO) and analog input/output (e.g., 8 AI/8 AO), supporting 16-bit resolution and electrical isolation (isolation voltage ≥1000V DC) to prevent interference and improve reliability.
Motion Control Unit: Optimizes electronic cam and multi-axis synchronization algorithms, supports the CiA 402 protocol, and can directly connect to servo drives to achieve real-time control of motor torque, speed, and position (e.g., synchronous axis position error

II. Communication and Data Processing Flow

Bus Communication Mechanism

EtherCAT Real-time Communication:
Constructs a ring network topology via RJ45 interface, supporting ≥65,535 slave stations in a single ring network with communication delay
Protocol Conversion Function:
As a gateway, it can convert protocol data such as CANopen and Modbus RTU into Ethernet/IP or OPC UA to achieve integration of different systems (e.g., connecting sensors to SCADA or MES systems), adapting to Industrial Internet of Things (IIoT) requirements.

Data Acquisition and Processing

Signal Input:
DI channels collect field switching signals (24V DC, response time
Instruction Output:
Receives DO/AO instructions from the master station (PLC/DCS), converts them to analog signals via DAC or directly drives digital outputs (e.g., transistors/relays, maximum load 2A), supports edge-triggered interrupts (response time

III. Motion Control and Real-time Control Logic

Multi-axis Synchronization Control

Adopts optimized electronic cam algorithms to achieve position and speed synchronization of multi-axes (e.g., servo motors, stepper motors) via the EtherCAT bus. For example, in packaging machinery, it controls the synchronous movement of cutting blades and conveyor belts to ensure a position error
Supports the CiA 402 protocol, directly communicates with servo drives, real-time monitors motor status (torque, speed, temperature), and adjusts parameters through closed-loop control to improve motion accuracy.

Application Scenario Control Logic

Automotive Production Lines: Achieves multi-station synchronous control of welding robots and material sorting equipment through electronic cams for precise positioning of stamping machines.
Logistics Sorting: Utilizes the high-speed response of the EtherCAT bus to control the action of sorting valves and conveyor belt speed, enabling precise sorting of packages (response time

IV. Reliability and Safety Design

Hardware Protection Mechanism

Electrical Isolation: Optoelectronic isolation between I/O channels with isolation voltage ≥1000V DC prevents surges and electrostatic interference; supports short-circuit protection, overload detection, and hot-swapping to reduce maintenance downtime.
Environmental Adaptability: Operating temperature -20℃~+60℃, humidity 5%~95% (non-condensing), protection class IP20 (panel mounting), meeting the requirements of harsh industrial field environments.

Redundancy and Self-diagnosis

Ring Network Redundancy: Supports EtherCAT DCIR (Dynamic Configuration Ring Network Redundancy) with switching time
Self-diagnosis Function: Real-time monitors faults (e.g., overvoltage, communication timeout) through LED indicators (power, communication, I/O status) and diagnostic buffers, and records logs for maintenance.

Application Fields

Industrial Control DCS Systems: Can be used as spare parts in various industrial control systems (e.g., Invensys Foxboro's IA series systems), undertaking functions such as sequence control, ladder logic control, accident recall processing, digital-analog conversion, I/O signal processing, data communication, and processing.
