GE IS215VCMIH2B VME Bus Master Controller Board

GE IS215VCMIH2B VME Bus Master Controller Board

The IS215VCMIH2B VME Bus Master Controller (VCMI) board is the communication interface between the controller and the I/O boards, and the communication interface to the system control network, known as IONet. VCMI is also the VME bus master in the control and I/O racks, and manages the IDs for all the boards in the rack and their associated terminal boards. There are two major versions of the VCMI board  (VCMIH1/VCMIH2.)

Multiple I/O racks can be connected to the IONet, each rack with its own VCMI board. Three simplex system configurations with local and remote I/O using the VCMI.

Two sizes of triple modular redundant (TMR) systems: 

The first example is a small system where all the I/O is mounted in the VME control rack so no remote I/O racks are required. Each channel (R, S, T) has its own IONet, and the VCMI has three IONet ports. 

The second example is a larger system with remote I/O racks. Each IONet supports multiple I/O racks, but only one rack is shown here. All I/O channels (R, S, T) are identical in terms of I/O boards and points.

The VCMI card receives analog and digital feedback of power status through the J301 backplane connector.

Diagnostics 

The internal +5 V, ±12 V, ±15 V, and ±28 V power supply buses are monitored and alarmed. The alarm settings are configurable and usually set at 3.5%, except for the 28 V supplies, which are set at 5.5%. 

Diagnostic signals from the power distribution module (PDM), connected through J301, are also monitored. These include ground fault and over/under voltage on the P125 V bus, two differential ±5V dc analog inputs, P28A and PCOM for external monitor circuits, and digital inputs.
