Product Overview
The GE IS215VCMIH2BC is a VME Communications Interface Module used in the GE Mark VI Speedtronic control platform. It serves as a communication interface within the VME-based control architecture, linking system boards and external communication paths used by the turbine control system.
The module is used in Mark VI control cabinets where communication between the main controller, I/O hardware, and other system devices is handled through the VME architecture and network interfaces. It operates alongside other Mark VI boards rather than functioning as the primary control processor.
For maintenance work, the IS215VCMIH2BC can be treated as a board-level communication assembly within the Mark VI system. Proper identification of the board revision and existing system configuration is important when selecting a replacement.

Working Principle
The IS215VCMIH2BC handles communication traffic between the Mark VI control architecture and connected communication paths. Incoming data is processed by the board and transferred to the appropriate system hardware through the VME architecture.
The VME backplane provides the internal connection between the VCMI module and other boards installed in the Mark VI rack. This allows control and I/O-related data to move between the different functional sections of the system.
External communication is handled through the supported network and serial interfaces. The VCMI circuitry processes these communication tasks while the main Mark VI controller continues to execute the system’s control logic.

Installation and Maintenance
- Verify the IS215VCMIH2BC identification before installation and confirm that it matches the intended Mark VI system.
- Shut down system power and follow the applicable electrical safety procedures before removing the existing module.
- Inspect the VME rack and backplane for contamination, damaged connectors, or loose mechanical hardware.
- Examine the board for overheating, corrosion, damaged components, or cracked solder joints.
- Check the card guides and ensure that the module is aligned correctly with the intended VME position.
- Insert the board evenly into the rack and ensure that the backplane connector is fully seated.
- Inspect Ethernet, RS-232C, and other communication cables before reconnecting them.
- Check communication connectors for loose contacts or physical damage.
- Restore power according to the approved Mark VI startup procedure.
- Check system diagnostics and communication status after installation.
- If communication faults occur, inspect the VME connection, network cabling, connected devices, and system configuration before replacing the module.
- When replacing the VCMI module, compare its identification and revision information with the existing hardware before commissioning the replacement.
