GE IC698ETM001 промышленный Ethernet-коммутаторный модуль

I. Основные технические параметры

Базовая коммуникационная способность

Конфигурация портов: 8 сетевых портов RJ45, поддерживающих адаптацию 10/100 Мбит/с, способных подключать множество ПЛК, датчиков, HMIs и других устройств, удовлетворяющих требованиям малых и средних промышленных сетевых узлов.

Пропускная способность шасси: 16 Гбит/с и полная линейная скорость передачи. Даже при одновременной коммуникации нескольких устройств задержек нет. Например, на автомобильной сборочной линии можно одновременно передавать данные от нескольких роботов и приборов, обеспечивая реальность времени.

Сетевые связи и управление

Таблица MAC-адресов: 8K записей, способная идентифицировать и управлять MAC-адресами большого количества устройств, подходящая для сценариев многоуровневого доступа на фабриках. Даже на умных фабриках, где подключено к сети сотни устройств, она может стабильно их идентифицировать.

Поддержка VLAN: На основе IEEE 802.1Q можно разделить до 256 VLAN, которые могут изолировать различные бизнес-потоки, такие как производственный контроль и управленческие данные. Например, на фабрике можно разделить сетевые системы управления оборудованием и офисные сети, чтобы повысить безопасность и эффективность.

Протокол избыточности: Поддерживает кольцевую (самовосстанавливающуюся <300ms), STP/RSTP, to build ring and tree-shaped redundant networks. When a certain link/device fails, it can be quickly switched to ensure uninterrupted operation in critical scenarios such as petrochemical and power.

The environment is compatible with the installation

Power supply: 24VDC input, typical power consumption of 10W, supports redundant power supply, universal DC power supply for industrial sites, redundant design to avoid power outage risk, suitable for 24-hour operation requirements of factories.

Temperature: -20℃ to +60℃, industrial-grade wide temperature range, capable of withstanding harsh environments such as cold workshops and high-temperature production lines. For instance, it can operate stably in steel mills and outdoor substations.

Installation: DIN rail installation, compatible with RX7i racks, conforming to the standardized installation method of industrial cabinets, facilitating integration into existing automation systems and reducing deployment costs.

Protection: IP20 dust-proof, needs to be installed in the control cabinet, suitable for industrial closed cabinet environments, preventing dust from entering and extending the service life of the equipment.

Ii. Working Principle and Network Architecture

1. Exchange and forwarding mechanism

Store-and-forward mode: Receive complete data frames → Check CRC→ Search the MAC address table → Forward to the target port to ensure data accuracy.

Line-speed forwarding capability: Each port supports a forwarding rate of 14,880 frames per second (100Mbps), meeting the requirements of high-speed data exchange.

2. Redundant network construction

Ring Network self-healing: Supports GE's proprietary Ring protocol. When a link in the network is disconnected, communication can be automatically restored within less than 300ms (for example, when the network cable is accidentally damaged in the production line).

Dual power supply redundancy: Two 24VDC power supplies are connected through the backplane. When one fails, it automatically switches to avoid network interruption caused by power supply issues.

3. QoS and Traffic Control

802.1p Priority: Supports 4-level priority queues to ensure that critical control instructions (such as emergency stop signals) are transmitted first.

Port mirroring: It can copy the traffic of a specific port to the monitoring port for network fault diagnosis.

Iii. Typical Application Scenarios

Automobile manufacturing production line

Application requirements: High-speed communication between PLC and robots, vision systems, and AGV carts, with a network latency of no more than 1ms.

Adaptation solution:

It adopts a ring topology, with 8 ports connected to multiple robot controllers.

Isolate production data from the management network through VLAN to ensure real-time performance.

The self-healing feature of the ring network ensures that a single link failure does not affect the operation of the entire line.

2. Smart Substation

Application requirements: Data interaction of protection devices and measurement and control units under the IEC 61850 communication protocol requires high reliability.

Technical advantages:

Support the STP protocol to build acyclic networks;

The wide-temperature design is adapted to the outdoor cabinet environment.

Support the connection between Modbus TCP and the SCADA system.

3. Distributed control system for Water Treatment plants

Application requirements: Connect multiple remote I/O stations with the central PLC, covering a wide area of the factory.

Deployment plan:

Expand the transmission distance (up to 20km) through an optical fiber converter (external connection required);

Redundant power supply ensures uninterrupted operation for 24 hours;

The port traffic monitoring function assists in troubleshooting abnormalities such as pipeline leakage.

Iv. Key Features and Usage Points

Status monitoring and diagnosis

LED indicator lights: Each port is equipped with a Link/Act (connected/active) indicator light to display the network status in real time.

Web interface: View port statistics (such as packet loss rate, traffic trends) through the built-in web server (IP address configurable).

2. Security and Configuration Management

Access control: Supports access filtering based on MAC addresses to prevent illegal device access;

Configuration backup: The switch configuration can be saved to an SD card (external connection required) for quick recovery.

3. Installation and Compatibility

Plug and play: It can be directly integrated with RX7i series PLCS (such as IC698 and CPU680) without complex configuration.

Protocol support: Compatible with mainstream industrial protocols such as EtherNet/IP, Modbus TCP, PROFINET, etc.

V. Selection and Deployment Suggestions

Number of ports: Select based on the number of connected devices. A typical configuration is:

Small-scale system: 4-6 ports for I/O station connection;

Large-scale system: 8 ports + external optical fiber expansion.

Topological structure

Circular: Suitable for scenarios with high reliability requirements (such as chemical industry and power);

Star shape: Suitable for centralized control (такие как интеллектуальное складское хранение).
