About the IS200VCMIH1B
This IS200VCMIH1B VME Communication Board printed circuit board product offering from General Electric was originally designed and manufactured specifically for insertion in the automated drive assembly of the trusted brand's Mark VI Turbine Control System Series in specific, as is evidenced above in this IS200VCMIH1B VME Communication Board device's brief product description paragraph above. The Mark VI Turbine Control System Series that this IS200VCMIH1B VME Communication Board product was developed for is for all intensive purposes quite the significant functional upgrade upon the previously-developed Mark V Turbine Control System Series of an extremely similar full extended product series title, as the Mark VI Series added the alternative energy-based wind turbine possible functional application onto the gas and steam-based environments established with the prior release of the mark V Series. This IS200VCMIH1B VME Communication Board device's Mark VI Series is additionally seen as valuable due to its nature as one of the final-released GE Mark product series to use the Speedtronic control system technology released with the Mark I way back in 1969.
Hardware Tips and Specifications
The IS200VCMIH1B is a VCMI Communication Board for the Mark VI system. It utilizes SIFT Voting (Software Inplemented Fault Tolerance) as a feature built into the board. Along with other VCMI boards located in the Mark VI control rack, the IS200VCMIH1B allows for communication with I/O boards. The IS200VCMIH1B is built with a front faceplate. The faceplate has many components mounted into its surface. Starting at the top of the faceplate, these include: a single line of three LED lights followed by a reset switch, a 9-pin serial port connector, two rows of four LED indicators that are all labeled “module,” followed by two rows of three LED indicators labeled R, S, and T. Finally, the board has another single line of three LED lights that is followed by a DIN connector. Each of these components is wired to the surface of the IS200VCMIH1B board. The IS200VCMIH1B is built with two backplane connectors. These are placed side-by-side on the rear edge. The board has two other pin connectors that are both located behind the front faceplate. This includes a vertical pin connector and a male vertical pin ribbon connector. The board also has several connectors made from conductive traces on the board.
The IS200VCMIH1B is mounted in the Central Control Module and is used for internal communications between I/O cards in various locations. When this card is replaced, it is important to note the rack needs to be powered down and the IONet connector must be unplugged from the board front before beginning the process. This leaves the network still running through the T-fitting. Full replacement instructions for this board can be found in GE publication GEH6421 Vol I. According to the IS200VCMIH1B VME Communication Board instructional manual attached in the manuals tab above, this IS200VCMIH1B VME Communication Board device utilizes SIFT or Software Implemented Fault Tolerance voting in its normal Mark VI Series assembly to establish normative processes. The backplane VME Bus in the greater Mark VI Series automated assembly is crucial in the result interpretation of this IS200VCMIH1B VME Communication Board process. This IS200VCMIH1B VME Communication Board PCB is actually not the originally-developed device of its specific GE Mark product series functionality, as that would have to be detailed as the IS200VCMIH1 parent VME Communication Board not utilizing this IS200VCMIH1B VME Communication Board device's sole B-rated functional product revision.
