Functional Description

The IS215VCMIH2CC is a GE-developed bus master controller module that is part of the Mark VI control system.

It is part of the Mark VI control system.The VCMI bus master controller plays a key role in the system architecture as an integrated communications interface that coordinates the exchange of data and commands.

As the link between the master controller and the array of I/O boards, the VCMI ensures smooth and efficient communication channels and facilitates seamless integration of the various components.

In addition, VCMI’s importance is reflected in its connection to the wider system control network, known as the IONet, which plays a vital role in coordinating communications across the network infrastructure.

Features

A distinctive feature of the VCMI is that it acts exclusively as a VMEbus master within the control and input/output racks.

The VCMI is responsible for the VMEbus, a standardized computer bus structure, and oversees the coordination of data transfer and control signals within these racks.

The VCMI manages the assignment of unique identification (ID) to all boards in the rack and their associated terminal boards.

This ID management function ensures that the various components within the rack are identified and interacted with in a systematic and organized manner, thereby increasing the overall efficiency and reliability of the system.

The VCMI Bus Master Controller is a multifaceted communications hub that seamlessly www.abb-drive.com connects controllers, I/O boards and the broader system control network.

As a VME Bus Master Controller in a given rack, it enhances its ability to manage and optimize the flow of information, ultimately improving the performance and cohesiveness of the integrated system.

The IS215AEPAH1A AEPA card module assembly is manufactured by GE Energy for use with the Mark VIe wind turbine control system family.

Product Description.

This IS215AEPAH1A printed circuit board was originally designed for General Electric’s Mark VIe series.

This Mark VIe series is a line of wind turbine system control and system control component products.

These products are actually manufactured by GE Energy, an alternative energy manufacturing company that exists as a shell company for retailers of the General Electric industrial giant.

This is a revised printed circuit board, modified from its original IS215AEPAH1 parent board by including a single-function revision rated “A”.

This GE Energy Mark VIe Wind Turbine Series PCB can be more accurately defined as an alternative energy power assembly by its functional description.

Hardware Tips and Specifications www.abb-drive.com

This IS215AEPAH1A Alternative Energy Power Assembly may be best understood when its hardware elements are contextualized according to the intended function of this printed circuit board.

The first descriptor for the function of this AEPA-abbreviated product is present in its functional description as an alternative energy power supply assembly.

This functional description happens to be an exact match to the AEPA functional acronym for this product, a rare blessing for a specialized Mark VIe series product.

The series to which this IS215AEPAH1A board belongs actually provides additional insight into the functionality of this product.

Considering the place of the IS215AEPAH1A PCB in the Mark VIe family of wind turbine control systems, it is not surprising that this GE Energy board is dedicated to wind turbine applications.

Now that the functional status of this IS215AEPAH1A PCB as an alternative energy power supply assembly has been described.

Then it is possible to highlight some of the hardware specifications available for this Mark VIe wind turbine series product.

Considering this product’s place in the specialized and recently developed Mark VIe wind turbine family, little original product-specific instruction manual material detailing the hardware of this IS215AEPAH1A PCB exists online.

That said, this initial Mark VIe series label identifies the board as an alternative energy power supply assembly with special component versions.

This IS215 series label has dual naming capabilities for this IS215AEPAH1A product; it also outlines its status as a domestic GE printed circuit board.

The original manufacturing location of this PCB can be traced more specifically to GE’s plant location in Salem, Virginia.

In this IS215AEPAH1A part number, the IS215 series label is followed by an example of the AEPA functional acronym.

It is itself followed by the H1 series grouping label, which, like the IS215 series label mentioned earlier, provides a dual naming convention for this product.

This H1 grouping label indicates that the product is a conformal coated printed circuit board with Mark VIe series grouping.

While the conformal style of PCB coating specific to this power supply assembly is well documented, given its widespread use on General Electric circuit boards, the first Mark VIe grouping of this part is the Mark VIe grouping.

The true meaning of the first set of Mark VIe series alignments for this component has been lost.

The last A digit of the IS215AEPAH1A part number is a reference to a Class A functional revision of this part, which may significantly affect the performance specifications and original measured dimensions of this IS215AEPAH1A product.
