FUNCTIONAL DESCRIPTION:

IS215UCVDH2AA is a Double-Slot Controller Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The UCVDH2A is a two-slot board that operates with a 300 MHz AMD K6 processor, supported by 8 MB of flash memory and 16 MB of DRAM. It offers network connectivity to the UDH through a 10BaseT Ethernet port with an RJ-45 connector. The board features two columns of eight status LEDs that cycle in a rotating pattern during normal function. In the event of a malfunction, the LEDs flash a coded sequence to signal the specific error.

UCVD OPERATION:

The controller operates with software tailored for steam, gas, land-marine aero-derivative (LM), or balance of plant (BOP) applications. It is capable of processing up to 100,000 rungs or logic blocks per second, based on a standard mix of average-sized blocks. An external clock interrupt allows the controller to synchronize with the VCMI communication board’s clock within a margin of ±100 microseconds.

Data exchange between the controller and the control system database (CSDB) occurs via the VME bus through the VCMI communication board. In a simplex setup, this data includes process inputs and outputs from the I/O boards. In a TMR configuration, the data comprises voted inputs from input boards, direct inputs from simplex boards, calculated outputs awaiting voting by the output hardware, and internal state information that needs to be shared among controllers.

UCVD CONTROLLER RUNTIME ERRORS:

In addition to generating diagnostic alarms, the UCVB and the UCVD controller boards display status information on front panel LEDs. The Status LED group on these controllers contains eight segments in a two-column vertical layout, as shown in the following figure. These LEDs display controller errors if a problem occurs. The rightmost column makes up the lower hexadecimal digit, and the leftmost column makes up the upper digit (the least significant bits on the bottom). Numerical conversions are provided with the fault code definitions.

If the controller detects certain system errors (typically during boot-up or download), it displays flashing and non-flashing codes on these green status LEDs. These codes correspond to runtime errors listed in the toolbox help file. The following table describes the types of errors displayed by the LEDs.
