Overview
The IS215VCMIH2BE is a VME Bus Master Controller Board manufactured by General Electric for the Mark VIe distributed turbine control system. It manages communication between the controller and I/O boards while providing an interface to the system control network, known as IONet. The board also manages board identification within the rack, supporting communication across local and remote I/O configurations.

Function and Communication
The IS215VCMIH2BE serves as the VME bus master in the control and I/O racks. It coordinates communication between the controller and the rack’s I/O boards, while also providing the communication path to IONet. This arrangement allows the control system to exchange data with the connected I/O hardware.
The board also manages identification for the boards installed in the rack and their associated terminal boards. Multiple I/O racks can connect to IONet, with each rack using its own VCMI board. This configuration supports distributed I/O arrangements with local or remote I/O, depending on the rack and system configuration.
Rack Installation Requirements
The control module includes a controller and a VCMI board. The documented installation arrangements use either a GE Fanuc integrator’s rack or a Mark VI rack. The integrator’s rack is shorter and serves standalone modules with remote I/O, while Mark VI racks support local or remote I/O.
A cooling fan mounts above or below the controller. A standalone control module using the GE Fanuc integrator’s rack also requires a VDSK board to provide fan power and rack identification through an ID plug. Confirm the rack type and required supporting hardware before installation.
Frequently Asked Questions
Q: What is the primary function of the IS215VCMIH2BE?
A: It acts as the VME bus master controller, coordinating communication between the controller, I/O boards, and IONet. It also manages board identification within the rack.
Q: Can the IS215VCMIH2BE support local and remote I/O?
A: The documented Mark VI rack configurations support local or remote I/O. The supported arrangement depends on the rack type and overall control system configuration.
Q: What should be checked before replacing this board?
A: Verify the complete model number, IS215VCMIH2BE, the rack type, the controller configuration, and the required supporting hardware. Check the electrical connections and applicable system documentation before installation.
