GE IS215UCVEH2A Mark VI Controller Module

GE IS215UCVEH2A Mark VI Controller Module

Functional Description

The IS215UCVEH2A controller is a single-slot VME board, housing a high-speed processor, DRAM, flash

memory, cache, an Ethernet port, and two serial RS-232C ports. It must always be inserted in slot 2 of an I/O

rack designed to accommodate it . These racks can be identified by the fact that there are no J3 and J4

connectors under slot 2. The controller provides communication with the UDH through the Ethernet port,

and supports a low-level diagnostic monitor on the COM1 serial port . The base software includes

appropriate portions of the existing Turbine Block Library of control functions for the steam, gas, and Land-

Marine aero-derivative (LM)products . The controller can run its program at up to 100 Hz, (10 ms frame rate),

depending on the size of the system configuration.

External data is transferred to/from the controller over the VME bus by the VCMI communication board. In a

simplex system, the data consists of the process I/O from the I/O boards, and in a TMR system, it consists of

voted I/O.
