The IS420ESWBH2A is an Ethernet Switch Module in GE's Mark VIe series control systems. It is primarily used for high-speed data communication within the Mark VIe control system and with external devices, enabling network interconnection of control modules, I/O modules, HMIs, host computers, and other equipment. It is a key component ensuring the reliability and real-time performance of system data transmission. Below is its detailed information:
- Module Type: Industrial-grade Ethernet switch module supporting redundant network architecture, specifically designed for the communication needs of the Mark VIe control system.
- Port Configuration: Typically equipped with multiple Gigabit Ethernet ports (specific quantity varies slightly by model, typically 8 or more), supporting RJ45 interfaces to meet the simultaneous access requirements of multiple devices.
- Network Standards: Compatible with IEEE 802.3 series Ethernet standards, supporting 10/100/1000 Mbps adaptive rates, ensuring compatible communication with devices of different speeds.
- Redundancy Function: Supports network redundancy protocols (such as MRP, RSTP, etc.), enabling the construction of ring or star redundant network topologies. When a link fails, it can switch to the backup link within milliseconds to ensure uninterrupted communication.
- Switching Capacity: Features wire-speed switching capability and supports full-duplex communication, reducing data transmission delay to meet the real-time requirements of industrial control (typical delay below 10 microseconds).
- Power Requirement: Powered by a Mark VIe system redundant power module (e.g., IS220PPROS1B) with 24VDC, equipped with overvoltage and overcurrent protection functions.
- Operating Environment:
- Operating temperature: 0°C to 55°C
- Storage temperature: -40°C to 85°C
- Humidity: 5% to 95% RH (non-condensing)
- Protection level: Industrial-grade design with vibration resistance and electromagnetic interference (EMI) resistance, suitable for harsh on-site environments such as power plants and heavy industry.
- High-Reliability Network Architecture: Supports redundant network design, eliminating the risk of single-point failures through dual network paths, ensuring continuous transmission of critical control system data (e.g., control commands, status feedback).
- Low-Latency Real-Time Communication: Optimized hardware design and switching algorithms reduce data forwarding delay, meeting the strict requirements for real-time data interaction in scenarios such as turbine control (e.g., millisecond-level response).
- Network Management Function: Supports SNMP (Simple Network Management Protocol), allowing monitoring of port status, traffic statistics, fault alarms, etc., through network management software, facilitating remote diagnosis of network issues by maintenance personnel.
- Enhanced Security: Supports port isolation, VLAN (Virtual Local Area Network) division, etc., which can isolate the control network from other networks, preventing unauthorized access and data interference, and improving system security.
- Plug-and-Play and Compatibility: Specifically designed for the Mark VIe system, it seamlessly integrates with the same series of processor modules (e.g., IS220UCSAH1A), I/O modules, etc., supporting rapid deployment and integration into the system without complex configuration.
- Construction of internal networks in gas turbine and steam turbine control systems (Mark VIe), connecting CPU modules, I/O modules, HMI terminals, and other devices.
- Enabling communication interconnection between the Mark VIe system and upper-level systems (such as DCS, SCADA) in thermal power plants and combined cycle power plants.
- Serving as a core network switching node in control systems of large industrial equipment in petrochemical, metallurgical, and other industries, coordinating data transmission among various control components.
- Building redundant industrial Ethernet to ensure stable transmission of critical control signals (such as real-time data on speed, temperature, pressure, etc.).
- Exclusively applicable to the GE Mark VIe control system, requiring compatibility with the same series of backplanes, power modules, and network components.
- Supports integration with GE ControlST software, allowing configuration of network parameters, redundancy strategies, VLAN division, etc., through the software.
- Compatible with industrial standard Ethernet devices, enabling cross-system communication with third-party HMIs, data acquisition servers, etc.
Through stable network switching capabilities and redundant design, this module provides an efficient and reliable data transmission channel for the Mark VIe control system, serving as an important communication component ensuring the smooth operation of automated control for large industrial equipment.
