The GE IS215VCMIH2BB IS200VCMIH2BCC is a VME Communications Interface Module used in the GE Mark VI Speedtronic control platform. The IS200VCMIH2BCC identifies the associated VCMI circuit board, while the IS215VCMIH2BB identifies the larger board assembly.
The VCMI module handles communication tasks within the VME-based Mark VI architecture. It connects with other control boards through the VME backplane and supports the exchange of operating data between the control system, I/O hardware, and connected communication interfaces.
In a turbine control cabinet, the module operates as communication infrastructure rather than as the primary controller. Its position in the VME architecture allows communication functions to be handled alongside the dedicated control and I/O boards installed in the same system.

The IS215VCMIH2BB receives communication information from connected interfaces and processes the data through its onboard communication circuitry.
Inside the Mark VI rack, the VME backplane provides the internal path between the VCMI module and other installed control boards. Data can move between the communication module, controller, and I/O hardware through this shared system architecture.
For external communication, the module handles data through its supported network and serial interfaces. The onboard processing circuitry manages communication-related operations before information is passed to the appropriate system component.

IS215VCMIH2BB identifies the VCMI board assembly, while IS200VCMIH2BCC identifies the associated VCMI circuit board. Both designations can be used when identifying the complete hardware.
VCMI refers to the communications interface function of the board. The module is used to handle communication between components of the VME-based Mark VI control architecture.
No. It is a VME Communications Interface Module. The primary control logic is handled by the appropriate Mark VI controller, while the VCMI module supports system communication.
The assembly number, base-board identification, board revision, VME installation position, connectors, and communication wiring should be checked against the existing installation before commissioning the replacement.
