ALSTOM MCHN02D1AB0004A Módulo de expansión de bus

Rendimiento potente del sistema de control
Se puede utilizar en conjunto con los PLCs medianos y grandes de la serie Hecin CTH300, que cuentan con grandes espacios de programa y datos, una fuerte capacidad de expansión y velocidades de escaneo del procesador rápidas.

Control de bus de alta velocidad
Adopta la conexión del bus EtherCAT de alta velocidad, con un cableado sencillo, una alta precisión de control, una velocidad rápida y una respuesta en tiempo real.

Depuración y monitoreo convenientes
El software CODESYS permite la visualización y el seguimiento efectivos de las curvas de cambio de variables correspondientes para facilitar el ajuste. El uso de cámaras electrónicas permite un mejor control del proceso.

Arquitectura de bus
El módulo utiliza EtherCAT (Tecnología de automatización de control Ethernet) como bus de comunicación de alta velocidad, lo que admite el intercambio de datos en tiempo real entre sistemas de E/S distribuidos y controladores maestros (como PLCs, DCS).
Con una tasa de comunicación de hasta 100 Mbps, una red de anillo única admite hasta 65,535 estaciones esclavas, lo que garantiza una transmisión de datos de baja latencia (tiempo de ciclo típico <1ms) and high-precision synchronization.

Protocol Adaptation
Supports protocol conversion for Modbus RTU/TCP and Ethernet/IP, and can act as a gateway to connect devices with different communication standards, enabling seamless integration of multi-protocol systems.
Communication parameters (such as IP address, slave station ID, data mapping) are configured through the CODESYS programming environment, supporting IEC 61131-3 standard programming languages (such as LD, FBD, ST).

Signal Acquisition and Conversion
The module acquires field device signals (such as sensor status, temperature/pressure values) through digital or analog input channels (such as DI, AI).
Signals are converted to digital quantities by an ADC (Analog-to-Digital Converter) with a typical resolution of 12-16 bits, and transmitted to the microprocessor via the internal bus.

Data Frame Processing
The microprocessor encapsulates the acquired data into EtherCAT data frames, following the Mailbox Protocol or Process Data Object (PDO) format.
Data frames are sent to the master station via the physical layer (such as RJ45 interface), which parses them to execute logic operations or control algorithms.

Control Command Response
The module receives control commands (such as DO output values, parameter settings) from the master station, converts them to analog signals via a DAC (Digital-to-Analog Converter) or directly drives digital output channels.
Supports Distributed Clock Synchronization (DC) to ensure timestamp consistency across all devices in the system, enabling high-precision motion control (such as electronic cams, synchronized axes).

High-speed I/O Processing
Supports fast input response (such as edge triggering, interrupt handling) with a typical response time <100μs, suitable for emergency stop (E-Stop) or high-speed counting scenarios.
Digital output channels have short-circuit protection and overload detection functions, which can automatically cut off faulty loops and report status.

Redundancy and Reliability Design
Supports EtherCAT ring network redundancy (DCIR), automatically switching to the backup path when the link is interrupted, with a recovery time <1ms.
Built-in watchdog timer and self-diagnosis function continuously monitor module status (such as power voltage, temperature), triggering alarms or safe modes in case of anomalies.

Parameterization and Configuration
Communication parameters, I/O mapping, and functional characteristics are defined via EDS files (Device Description Files), allowing the master station to automatically identify and configure slave stations.
Supports hot-swapping, enabling module replacement without powering off, reducing system maintenance time.

Motion Control Integration
Works with servo drives and stepper motors to achieve multi-axis synchronous control (such as electronic cam curves for packaging machines, printing presses).
Supports motor status monitoring (such as torque, speed) and fault diagnosis via the CiA 402 protocol.

Distributed I/O System
As a remote I/O station, it expands the I/O points of the master controller, suitable for large production lines (such as automotive manufacturing, logistics automation).
Supports mixed I/O configuration (such as DI/DO, AI/AO, temperature measurement modules) to meet diverse application needs.

Industrial Internet of Things (IIoT) Connection
Uploads field device data to SCADA systems or cloud platforms via protocol conversion for remote monitoring and data analysis.
Supports OPC UA interfaces, providing standardized data access for smart manufacturing.

Status Indication
The module is equipped with LED indicators showing power status, communication status, and I/O channel status for quick on-site fault troubleshooting.

Diagnostic Data
Reads the diagnostic buffer via CODESYS or dedicated configuration tools to obtain historical fault information (such as overvoltage, communication timeout).
Supports heartbeat message and device status word monitoring to track module operational health in real time.

Equipment Control
Suitable for dual-station equipment, enabling control and triggering of odd/even numbers. For example, in dual-station processing equipment on automated production lines, precise control can be achieved via this module.

Motion Control
Can be used to control the speed of transmission belts, capping torque, and the matching of lifting shaft speed and capping rotations during capping. It has broad application prospects in capping equipment for the food and pharmaceutical packaging industries.
