GE Mark VI Series IS215VCMIH2B VMEbus Master Controller

Specification

Part Number: IS215VCMIH2B

Manufacturer: General Electric

Country of manufacture: USA

Product Type: VMEbus Master Controller

Series: Mark VI

Availability: In stock

The IS215VCMIH2B is a VME communications interface card manufactured by General Electric as part of the Mark VI family for gas turbine control systems.

The VME Bus Master Controller (VCMI) board serves as the communications interface between the controller and I/O boards, as well as with the IONet system control network.

The VCMI also acts as the VMEbus master controller in the control and I/O racks, managing the IDs of all boards in the rack and their associated terminal blocks.

Through the J301 backplane connector, the VCMI card receives analog and digital feedback on power status.

There are two versions of the VCMI board: VCMIH1 and VCMIH2.The board has four port connections on the front panel.

The board has four port connections on the front panel, including three IONet connectors and one serial port. There are three LEDs above each IONet connector.

“TX”, ‘RX’ and ‘CD’ are the labels on them. The panel also contains four LEDs labeled 1. 2. 4. and 8. as well as LED indications labeled Run/Fail/Status (located above the pushbutton reset switch).

The panel attaches to the motherboard using screws.

Features of the IS215VCMIH2B

Board Type: 6U high VME board, 0.787 inches wide

Processor: The TMS320C32 is a 32-bit digital signal processor from Texas Instruments (TI).

Memory

32 KB dual-port memory in 32-bit transfer configuration

256k x 32 SRAM

512k x 8-VCMIH B; 4096K x 8-VCMIH C Flash memory

Communication

H1 version - 10 Mb/s, 1 IONet 10Base2 Ethernet port, BNC connector

H2 version - 3 IONet 10Base2 Ethernet ports, BNC connectors, 10 Mbits/sec

VME Bus Block Transmission: 1 RS-232C serial port with D-plug connector and 9600 baud rate (only)

Frame rate (FR): TMR 20 ms, 80 ms depending on application, simplex 10 ms (100 Hz) TMR 40 ms (25 Hz)

Diagnostics: Monitoring and alarming of the internal power bus for +5 V, 12 V, 15 V and 28 V. The internal power bus can be set to 5.5% of 28 V.

Alarm settings are customizable except for the 28 V power supply, which is set to 5.5% and is typically set to 3.5%.

The accompanying diagrams show three simplex system setups using VCMIs with local and remote I/Os. Each I/O rack has its own VCMI board and many of the I/O racks can be connected to an IONet.

A second IONet port on the VCMI can be used as a parallel IONet to increase data throughput for applications requiring low latency, as shown in the lower half of the accompanying figure.
