Description
GE IS200ESYSH1AAA — Ethernet Switch Module (ESW)
Product: IS200ESYSH1AAA, Ethernet Switch Module
Manufacturer: GE (General Electric), part of the Mark VIe Speedtronic Turbine Control System family
Primary Application: A managed industrial Ethernet switch module that provides networked communication capabilities within the GE Mark VIe control system, primarily used to form the Ethernet Control Network (ECN) for high-speed, deterministic data exchange between controllers, I/O packs, and operator interfaces.
1. Core Overview & System Context
The GE IS200ESYSH1AAA is a critical networking component in the Mark VIe architecture. The «ESYS» in the part number stands for Ethernet SYStem module. It functions as an embedded, ruggedized Ethernet switch designed specifically for the harsh electrical and environmental conditions of power generation and industrial applications.
Key Role: It serves as the local networking backbone within a turbine control cabinet or across multiple cabinets, enabling controllers (e.g., TMR controllers), I/O packs, and other intelligent devices to communicate using standard Ethernet protocols in a reliable, deterministic manner.
2. Key Features & Functions
-
Managed Switch Capabilities: Provides advanced network management features such as:
-
VLAN (Virtual LAN) Support: For segmenting control traffic and improving network security/performance.
-
IGMP Snooping: Efficiently manages multicast traffic (important for peer-to-peer controller communication).
-
Quality of Service (QoS): Prioritizes critical control traffic over other data.
-
Port Configuration: Allows setting of speed, duplex mode, and enabling/disabling of individual ports.
-
-
Deterministic Performance: Designed for real-time control systems, offering low-latency, high-reliability data transfer essential for turbine control.
-
Robust Hardware: Built to withstand industrial temperatures, vibration, and electrical noise.
-
Hot-Swappable: In systems designed with redundancy, the module can typically be replaced without powering down the network (if a redundant switch is online).
-
Network Diagnostics: Provides status information on port activity, link state, and network health, accessible via the Mark VIe engineering tool (ToolboxST).
-
Redundancy Protocols: Supports network redundancy protocols like STP/RSTP (Spanning Tree Protocol) to prevent network loops and ensure path redundancy.
3. Common Technical Specifications
-
Network Ports: Typically features multiple 10/100 Mbps Ethernet ports (e.g., 8, 12, or 16 ports) with RJ-45 connectors. Some ports may be designated for specific purposes (e.g., uplink, controller connection).
-
Switch Type: Managed Layer 2 Ethernet Switch.
-
Mounting: A single-slot VME board that plugs into a Mark VIe IS200-series rack (e.g., a controller rack or a dedicated communication rack).
-
Power: Powered directly from the VME backplane of the rack.
-
Management: Configured and monitored via ToolboxST software or, in some cases, via a web interface or command-line interface (CLI).
4. System Integration & Network Architecture
-
Role in Mark VIe Network: It forms the core of the Ethernet Control Network (ECN), which is a separate, isolated network from the plant’s business network.
-
Typical Connections:
-
Connected to Mark VIe Controllers (TMR, Simplex, Duplex).
-
Connected to distributed I/O Packs (via their communication modules).
-
May connect to operator stations (HMI) and engineering stations running ToolboxST.
-
May have an uplink port to connect to a higher-level plant network (e.g., for historian data) via a firewall.
-
-
Configuration: Network settings (IP addresses, VLANs, etc.) are configured within the Mark VIe system project using ToolboxST. The switch’s firmware is also managed through this tool.
5. Typical Applications
This module is used in any Mark VIe-controlled installation requiring robust networked communication:
-
Gas Turbine Power Plants (Heavy-duty & Aeroderivative).
-
Steam Turbine Control Systems.
-
Combined-Cycle Power Plants.
-
Compressor Control Stations.
