The GE IS215UCVGM06A is a Universal Control Variable Generator Module in the Mark VI
Speedtronic control system, designed for gas, steam, and
balance-of-plant turbine management. As a single-slot board, it
features a 650 MHz Intel Celeron processor, 128 MB flash memory,
and 128 MB SDRAM, running on the QNX real-time OS to execute
turbine application code efficiently.
Equipped with two 10/100BaseTX Ethernet ports, it connects to the
UDH via the first port and supports Modbus/EGD on a separate subnet
through the second. Integrating with the VME bus, it communicates
with I/O boards, syncing with the VCMI board’s clock for precise
timing. Its front faceplate includes ports, a reset switch, status
LEDs, and a PMC expansion slot, ensuring versatile operation.
Features:
Processing Power: 650 MHz Celeron processor handles up to 100,000 rungs/blocks per
second, supporting real-time turbine control logic.
Dual Ethernet Connectivity: Two ports enable UDH communication and isolated subnet use, with
toolbox-validated configurations on startup.
VME Integration: Communicates via VME bus with I/O boards, exchanging data in
simplex/TMR systems.
Robust Hardware: Includes a lithium battery, backplane connectors, and components
like inductors/resistors; front LEDs indicate operational status.
Mark VI Compatibility: Fits GE Fanuc/Mark VI racks, requiring a cooling fan and for
stand-alone setups a VDSK board for power/ID.
Functional Revision: A-rated revision enhances reliability, with “UCVG” in its part
number denoting its universal control role and domestic
manufacture.
