Technical Architecture & Functional Positioning
The IS215UCVEM09B functions as the central VME processor in Mark VI systems, particularly optimized for land-marine aero-derivative turbine controls and LCI applications. Installed in a single VME slot, it executes turbine application software under QNX RTOS, processes real-time data from I/O packs, runs governor/sequencer/protection algorithms, and handles communication over Ethernet and serial links to HMI/SCADA or external devices.
The board integrates a 300 MHz Intel Celeron processor with 32 MB DRAM and 16 MB CompactFlash storage, providing reliable non-volatile code persistence and sufficient memory for complex control strategies. Key technologies include high-speed Ethernet for IONet networking, diagnostic feedback channels, and support for DLAN+ in specific setups. These features address critical engineering requirements: deterministic loop execution for precise speed/load control in aero-derivative engines, robust communication in distributed marine environments, and fault-tolerant operation to minimize downtime in power generation or propulsion systems.
The M09 variant (UCVEM09B) offers a streamlined single Ethernet configuration with DLAN+ capability, making it suitable for applications where compact rack space and reliable legacy interfacing are priorities. Its architecture supports simplex or redundant configurations while enabling online diagnostics and maintenance access.
Typical Application Scenarios
- Deployed in aero-derivative gas turbines (land-marine variants) for core control of startup sequencing, speed governing, and protective functions in power generation or mechanical drive applications.
- Used in Mark VI LCI systems for coordinating inverter control, excitation, and turbine logic in industrial or marine propulsion setups.
- Serves as a replacement or spare in operational Mark VI installations, preserving existing VME racks and application configurations.
- Integrated in compressor or generator drive systems requiring high-reliability real-time processing under variable loads.
- Applied in retrofit or maintenance projects to sustain legacy Mark VI platforms with minimal system changes.
