Product Overview
The GE IS215UCCCM04AB is a UCCC CompactPCI controller module for the GE Mark VIe control platform. It provides the central processing resources required to execute turbine and plant-control applications, communicate with distributed I/O, and exchange data with higher-level control and supervisory systems. The UCCC architecture uses an Intel Pentium M processor and integrates the controller with an IS200EPMC PCI mezzanine card.
The GE IS215UCCCM04AB is based on the UCCC M04 hardware configuration, using a 1.6 GHz Intel Pentium M processor, 256 MB DDR SDRAM and 128 MB CompactFlash. GE documentation identifies two 10/100/1000Base-TX Ethernet ports for the Unit Data Highway (UDH) and optional Control Data Highway (CDH). The EPMC adds three Ethernet connections for the I/O networks.
The GE IS215UCCCM04AB operates within a 6U CompactPCI architecture and runs the QNX Neutrino real-time operating system. Its intended applications include turbine control and balance-of-plant systems where deterministic controller processing and distributed I/O communication are required. The Mark VIe documentation also identifies UCCC as a supported controller platform for control-block programming and discrete/analog control functions.

Main Features & Field Considerations
UCCC controller architecture
The UCCC is a controller rather than a conventional I/O board. The IS215UCCCM04AB executes the control application while communicating with Mark VIe I/O and other system components over the control and I/O networks.
1.6 GHz Pentium M processor
The M04 configuration uses an Intel Pentium M processor at 1.6 GHz. GE’s documentation distinguishes this from lower-performance UCC configurations, so the complete M04 designation should be retained when sourcing a replacement.
Integrated EPMC architecture
The UCCC assembly includes the IS200EPMC PCI mezzanine card. This provides additional Ethernet interfaces used for the I/O network architecture. A replacement should therefore be matched as a complete controller assembly rather than treating the processor board and EPMC as unrelated components.
QNX real-time operating system
The controller runs QNX Neutrino, supporting the real-time control environment used by Mark VIe. The application and operating environment should be considered together during replacement.
Network connectivity
Two 10/100/1000Base-TX ports provide UDH and optional CDH connectivity, while the EPMC supplies additional 10/100Base-TX I/O-network connections. Incorrect network assignment or IP configuration can prevent a replacement controller from joining an existing Mark VIe system correctly.
Controller diagnostics
Mark VIe controller diagnostics include CPU-temperature monitoring, watchdog functions, board-temperature monitoring, and EPMC power monitoring. The Mark VIe standard-block documentation confirms CPU and board temperature status functions for UCCA/UCCC controllers.
Replacement Checklist
Before replacing IS215UCCCM04AB, verify:
- Exact catalog number:
- UCCC controller family
- M04 processor configuration
- Hardware revision represented by the AB suffix
- IS200EPMC mezzanine card
- CompactPCI rack and slot
- Mark VIe ControlST/ToolboxST version
- Application software backup
- UDH configuration
- CDH configuration, if used
- IONet R/S/T configuration
- Controller redundancy arrangement
- CompactFlash contents
- RTC/battery condition
- Cabinet cooling and airflow
Procurement Note
The should not be confused with similarly named UCC/UCCA controller assemblies. GE’s documentation specifically identifies IS215UCCCM04 as the UCCC M04 assembly with the 1.6 GHz Pentium M, 256 MB DRAM, 128 MB flash, and IS200EPMC combination.
For replacement procurement, retain the complete identifier and verify the installed Mark VIe software/firmware environment. A board that is electrically and mechanically compatible can still require configuration or application restoration before it can assume control in an operating turbine system.
