Functional Description

IS200UCVEH1A is a Standard Controller Module developed by GE. It is a part of the Mark VI control system. UCVE boasts various forms, ranging from UCVEH2 to UCVEM01 through UCVMEM05. Each variant caters to distinct system demands and enhancements. UCVEH2 embodies the quintessential Mark VI controller. This single-slot board harnesses the prowess of a 300 MHz Intel Celeron processor, ensuring robust performance across control and monitoring operations. With options of 16 or 128 MB of flash memory and 32 MB of DRAM, UCVEH2 strikes a balance between storage capacity and processing efficiency.

Processing Power and Performance

• At the heart of the module lies a 300 MHz Intel Celeron processor, delivering dependable computational power for control, sequencing, and monitoring functions. This single-slot controller board is engineered for high reliability in mission-critical applications, where consistent processing performance directly influences turbine efficiency and plant safety.
• The UCVEH2 offers 16 MB or 128 MB of flash memory and 32 MB of DRAM, ensuring a balanced combination of storage capacity and execution speed. This architecture supports real-time control loops, diagnostic tasks, and data acquisition functions — all essential to maintaining precise and stable system operations.

Ethernet Connectivity

10BaseT/100BaseTX (RJ-45) Ethernet port facilitates communication over GE’s Unit Data Highway (UDH) network. This network connection enables seamless data exchange between the controller and other Mark VI components, such as operator interfaces, HMIs (Human-Machine Interfaces), and remote I/O modules.

Through Ethernet connectivity, users benefit from:

• Rapid data transfer for real-time process monitoring and control.
• Remote configuration and firmware updates, reducing downtime and simplifying maintenance.
• Efficient system diagnostics and fault detection, ensuring early intervention during anomalies.

This robust communication interface transforms the UCVEH2 into a highly integrated and network-aware controller capable of managing distributed automation tasks across complex industrial systems.

Memory Architecture: Flash and DRAM

The inclusion of both flash memory and dynamic random-access memory (DRAM) enhances the UCVEH2’s operational efficiency and data reliability.

• Flash Memory: Serves as non-volatile storage, retaining critical data such as firmware, configuration files, and control parameters even after power loss. This ensures that the system can recover swiftly after shutdowns without requiring manual reconfiguration.
• DRAM: Provides volatile memory used for high-speed data processing, temporary storage, and control logic execution. Its fast access times enable the controller to manage real-time control loops and data computations with precision.

Together, these memory components ensure that the UCVEH2 maintains a stable, responsive, and fault-tolerant performance across all operational conditions.

Ethernet Port Functionality

The Ethernet port is designed to support both 10BaseT and 100BaseTX Ethernet standards, offering flexible and reliable network connectivity. This dual compatibility enables the controller to adapt to various network infrastructures, offering options for both standard and high-speed data transfer. The Ethernet port enables the UCVEH2 to communicate efficiently with other devices within the Mark VI control system, such as human-machine interfaces (HMIs), data historians, and engineering workstations. By facilitating quick and stable data exchanges, the Ethernet functionality ensures smooth coordination across all system layers.

Integration with Unit Data Highway (UDH)

The controller is engineered to work in harmony with the Unit Data Highway (UDH), which serves as the primary communication backbone for the Mark VI system. This integration is fundamental to achieving cohesive and synchronized control system performance. Through its connection to the UDH, the UCVEH2 can interact with a wide range of devices, including input/output modules, operator interfaces, and system monitoring tools. This level of interoperability enables coordinated system behavior, facilitates timely data sharing, and enhances system awareness, all of which are crucial for maintaining operational reliability and efficiency.

Scalability and Flexibility

The design of the UCVE family, including the UCVEH2 model, emphasizes adaptability and modularity to meet a wide array of system requirements. With multiple variants available, each catering to specific control tasks, processing capabilities, and memory configurations, the UCVE lineup offers a scalable solution suitable for both small and large-scale industrial applications. As system demands evolve or expand, these controllers can be integrated, upgraded, or replaced with minimal disruption, making them a highly flexible option for long-term infrastructure planning and system growth.

Battery Connection for NVRAM and CMOS

• For seamless operation and data integrity within the Mark VI control system, it's imperative to correctly configure the battery connection. 
• Jumper Configuration: To establish connectivity for the batterie,s facilitating Non-Volatile Random Access Memory (NVRAM) and Complementary Metal-Oxide-Semiconductor
• (CMOS), adhere to the jumper configurations: Set jumper E8 to pins 7-8 (IN). Jumper E10 should also be set to (IN).
