IS215UCVEH2B is a UCVE controller assembly for the GE Mark VI turbine control platform. The UCVE controller is a VME-resident single-board computer that runs turbine application code under the QNX real-time multitasking operating system. It communicates with the Unit Data Highway through Ethernet and exchanges process I/O with the VCMI communication board across the VME bus.

ENGINEERING VIEW
Legacy Mark VI Control Path
Application processor The UCVE executes the configured turbine application, including sequencing, regulation and protection functions. The actual frame rate depends on project size and engineered loading.
VME relationship Process I/O is transferred over the VME bus through the VCMI communication board. In a TMR system, the controller receives voted I/O; in a simplex system, it receives the configured process I/O path.
Reserved rack slot The controller belongs in slot 2 of the compatible Mark VI I/O rack. This position is distinguished by the absence of J3 and J4 field-cable connectors beneath the controller slot.
UDH communication The Ethernet interface connects the controller to the Unit Data Highway for operator, engineering and peer communication. Network identity and project settings must be preserved during replacement.
Serial access COM1 supports initial setup and low-level diagnostic access; COM2 supports serial communication according to the installed arrangement. Do not change port use without checking the running project.
Revision control The complete IS215UCVEH2B code, attached assembly, rack, VCMI relationship, QNX image and application release must be matched. A visually similar UCVE board may not be a valid direct substitute.

UCVE controller Runs the Mark VI turbine application in the VME rack
VCMI board Transfers I/O and communication data across the VME bus
I/O boards Acquire and drive field signals through their terminal-board paths
UDH / HMI Provides operator, engineering and peer access over Ethernet
Compatibility depends on the complete assembly: hardware suffix, connected boards, network or backplane path, configured software release and the active plant application must be evaluated together.

PURCHASING QUESTIONS
IS215UCVEH2B FAQ
01
Can IS215UCVEH2B be installed in any open Mark VI rack slot? No. The UCVE controller uses the reserved controller position in slot 2 of a compatible Mark VI rack. Verify the rack construction before insertion.
02
What must be backed up before an IS215UCVEH2B exchange? Preserve the running Mark VI application, controller network settings, hardware assignment, QNX image compatibility and current diagnostic state.
03
Does IS215UCVEH2B communicate directly with field terminal boards? The controller exchanges process I/O across the VME bus through the VCMI and installed I/O boards. Field wiring terminates through the corresponding I/O and terminal-board arrangement.
04
What should be checked if IS215UCVEH2B boots but I/O remains unavailable? Check VCMI communication, VME seating, rack power, hardware assignment, controller application and the diagnostic state of the installed I/O boards.
05
Is IS215UCVEH2B interchangeable with every UCVE revision? No. Match the complete assembly code, processor generation, flash image, Mark VI release, rack arrangement and site application before approving a replacement.
