Functional Description

IS415UCVHH1AA is a Single-slot Controller Board developed by GE. It is a part of the Mark VIe control system. This controller serves as a processing unit within the Mark VIe architecture, integrating advanced computing power, flexible communication interfaces, and robust memory capacity to support critical control, protection, and monitoring operations in real time.

Processor and Memory Architecture

Intel Ultra-Low Voltage Celeron 1067 MHz (1.06 GHz) processor, designed for high efficiency and low power consumption—essential for continuous industrial operation where stability and endurance are critical.

The controller is equipped with:

• 128 MB of onboard flash memory, used for firmware storage, configuration files, and boot processes.
• 1 GB of SDRAM, providing sufficient capacity for real-time control logic execution, data buffering, and fast data retrieval.

This architecture enables the UCVH controller to execute complex algorithms, handle multiple data streams, and support fast response times, ensuring seamless control performance across turbine and plant systems.

Ethernet Communication and Networking

It features dual Ethernet ports (10BaseT/100BaseTX) using RJ-45 connectors, offering versatile communication capabilities within the Mark VIe environment.

Primary Ethernet Port (Port 1)

• Provides connectivity to the UDH (Unit Data Highway), which is the main control and communication backbone within the Mark VIe system.
• Supports peer-to-peer communication, enabling the controller to exchange data efficiently with other controllers, operator workstations, and network devices.
• Facilitates system configuration, diagnostics, and firmware updates through the GE ToolboxST™ software interface.

Secondary Ethernet Port (Port 2)

• Designed for use on a separate IP logical subnet, enhancing network segmentation and communication security.
• Can be configured for Modbus TCP/IP communication—commonly used for integration with third-party control systems, data historians, or distributed control systems (DCS).
• Alternatively, it supports Ethernet Global Data (EGD)—GE’s proprietary high-speed data exchange protocol, ensuring deterministic, time-synchronized communication between Mark VIe components.
• Configuration and IP assignments for this port are managed through ToolboxST™, allowing flexible network customization based on plant architecture.

Configuration and Validation

• Each time the control rack is powered up, performs an automatic hardware validation process. The controller verifies its ToolboxST configuration against the physically installed hardware to ensure consistency, detect mismatches, and prevent operational conflicts.
• This self-validation mechanism enhances reliability by ensuring that the controller’s operational parameters, firmware, and connected components align perfectly with the system configuration eliminating potential communication or logic execution errors before they can impact turbine operation.
