VME Bus and TMR Control Architecture

The IS215UCVEH2A controller card operates within the GE Mark VI turbine control architecture using VME backplane communication. The processor executes control algorithms, sequencing routines, and diagnostic tasks while exchanging data with connected I/O modules.

The controller supports Triple Modular Redundancy (TMR) operation, where three independent control lanes process and compare voting data. The voting mechanism allows fault detection and continued control execution when a single processing lane experiences a fault condition.

Frequently Asked Questions

Q: What type of processor is installed on the IS215UCVEH2A?
A: The module uses an Intel Celeron 300 MHz processor and operates with a QNX real-time operating system for deterministic control execution.

Q: What backplane interface does the IS215UCVEH2A support?
A: The controller uses a VME64 compliant interface with A32/D32 transfer modes for communication with Mark VI system modules.

Q: What power input is required for this controller card?
A: The module requires a +5 VDC supply with approximately 6 A typical current consumption and 8 A maximum current demand, with auxiliary +/-12 VDC inputs.

Field Installation Guidelines

Install the IS215UCVEH2A controller card into the designated 6U VME rack slot according to the Mark VI cabinet configuration documentation. Verify backplane connector alignment before insertion and ensure rack power is removed during installation or removal.

Use shielded communication cables for Ethernet and serial connections where required by the cabinet wiring design. Maintain separation between signal wiring and high-voltage or high-current conductors to reduce electromagnetic interference.

Confirm grounding continuity between the VME rack, cabinet chassis, and protective earth system. Verify firmware compatibility, I/O module addressing, and controller configuration parameters before system startup.
