IS215UCCAM03: The Mark VI CompactPCI Controller Module

The IS215UCCAM03 (also seen as IS215UCCAM03A) is a General Electric UCCx-series controller in module form — the CompactPCI (CPCI) compute engine that runs turbine application code in GE Mark VI and Mark VIe control systems. Where the VME-based UCVx controllers live in a VME rack, the UCCA is built on a single-board computer that seats in a CompactPCI enclosure. Published references describe the M03 as a module assembly: the UCCAH3 processor board combined with flash and DRAM memory and the IS200EPMC mezzanine card. It runs the QNX Neutrino real-time operating system and executes control logic as rungs or blocks.

What is inside the M03 assembly

The processor board is the brain: an Intel x86-class single-board computer with two PCI Mezzanine Card (PMC) sites and a watchdog timer. An RJ-45 10BaseT/100BaseTX Ethernet port connects to the Unit Data Highway (UDH) for the HMIs and other control equipment, while the IS200EPMC adds Ethernet ports for the <R>, <S> and <T> I/O network (IONet) and the physical-layer snoop hardware used for IEEE 1588 precision time synchronization — the mechanism that keeps controllers and I/O packs aligned to within about ±100 microseconds. An RS-232C COM1 port is used for setup. One honest caveat on specifications: the exact processor and memory fitted vary by build, so match your board's full part number rather than assuming a clock speed or memory size from the acronym alone.

Diagnose Before You Buy: Controller, IONet, or Configuration?

A controller that appears dead is often the victim of something around it. Before ordering a replacement M03, isolate the fault:

• Read the front-panel LEDs. They report power, flash-disk activity, reset, online status and Ethernet state — use them to tell a hung processor from a comms problem.
• Check power and the CPCI rack. In a CompactPCI rack the slot-1 board is the system board; if it is ejected or unpowered, the other controllers in the rack stop too. Confirm rack power before condemning the module.
• Mind the CMOS battery jumper. On boards taken from storage the battery jumper may be disconnected; a controller that will not hold its real-time clock or settings can look failed when it simply needs the jumper reinstalled and the clock reset (NTP or ToolboxST).
• Separate firmware/configuration from hardware. A failed application download, a firmware/ControlST mismatch, or an IONet addressing conflict imitates a bad controller.
• Look at the network and I/O packs. Lost UDH or IONet links, or a faulty I/O pack, can present as a controller fault that no new board will cure.

Replace the M03 once the rack power, battery/clock, configuration and network are proven good — not before.

How to read UCCA part numbers and the M03 suffix

The number decodes in blocks. IS215 is the Mark VI board/assembly family and GE lineage; UCCA is the CompactPCI controller function. The letter that follows tells you the form: an H number (for example UCCAH3) is the bare single-slot processor board, while an M number such as M03 is the complete module assembly — processor board plus memory and EPMC. Match the whole string, including the trailing revision letter. Our GE Speedtronic Part Number Decoder works through the fields, and the Mark V vs Mark VI: DS200 to IS200 guide explains where this generation sits.

Related controllers and companion boards

The UCCA is closely related to the VME-based UCVx controllers (UCVB/UCVD/UCVE/UCVG) and works with the VCMI communication interface and Mark VI I/O packs. Browse the GE Mark VI IS200 Boards collection for those companions, or the broader GE Speedtronic Turbine Control Boards range.
