Part Number is200vcmih2b Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI Function Module Availability In StockIS200VCMIH2B is a VME bus master controller board developed by GE. It is a part of Mark VI control system. The VCMI board in the control and interface module communicates internally with the I/O boards in its rack and via the IONet with the other VCMI cards. There are two versions, one for simplex systems with one Ethernet IONet port and one for TMR systems with three Ethernet ports. 

A single cable connects one control module to one or more interface modules in simplex systems. In TMR systems, the VCMI with three separate IONet ports communicates with the three I/O channels Rx, Sx, and Tx, as well as the two other control modules. FEATURES The VCMI board uses Software Implemented Fault Tolerance (SIFT) voting. Each of the R, S, and T VCMI boards votes on input data from each of the IONet connections. The results are sent to the controllers' control signal databases via the backplane VME bus. IONet can support multiple I/O racks, each with its own VCMI board. A second IONet port on the VCMI can be used as a parallel IONet to increase data throughput for applications requiring low latency.

Functional Description

IS200VCMIH2B is a VME bus master controller board developed by GE. It is a part of Mark VI control system. The VCMI board in the control and interface module communicates internally with the I/O boards in its rack and via the IONet with the other VCMI cards. There are two versions, one for simplex systems with one Ethernet IONet port and one for TMR systems with three Ethernet ports. A single cable connects one control module to one or more interface modules in simplex systems. In TMR systems, the VCMI with three separate IONet ports communicates with the three I/O channels Rx, Sx, and Tx, as well as the two other control modules.

Features

The VCMI board uses Software Implemented Fault Tolerance (SIFT) voting.

Each of the R, S, and T VCMI boards votes on input data from each of the IONet connections. The results are sent to the controllers' control signal databases via the backplane VME bus.

IONet can support multiple I/O racks, each with its own VCMI board. A second IONet port on the VCMI can be used as a parallel IONet to increase data throughput for applications requiring low latency.
