Product Description
The IS215VCMIH2C was designed as a VME Communication Card in a GE Mark VI Turbine Control System and is critical to the correct function of the system as a whole. The VCMI VME Communication board allows Input/Output (I/O) cards to communicate with other I/O cards that are mounted on the VME backplane, with I/O cards 
on expansion racks, with I/O backup protection modules, with triple redundant control modules, and with the primary or main processor module.
The IS215VCMIH2C card is also broadly referred to as a VME Bus Master Controller. This PCB interfaces communications among the I/O boards and the controller. It also acts as the communication interface to the system control network, or IONet.
The IS215VCMIH2C is built with four port connections placed into its front faceplate. These include an RS-232C Serial port, D-style plug connector, and three IONet 10Base2 Ethernet ports. Each of the IONet connectors is associated with three LED indicators that are labeled TX/RX/CD. The board has additional LED indicators that are labeled Status, Fail, Run, and 1,2,4, and 8. The former is placed above a reset switch (push button,) while the latter is directly below the serial port.
Each control module in the Mark VI system generally contains an IS215VCMIH2C, with these unique VCMI cards serving to communicate execution data with the main processor modules via the application software for the control system. Because of the critical nature of the VCMI modules, it is advisable to keep additional spares on the shelf to avoid a machine down situation.
FUNCTIONAL DESCRIPTION:
IS215VCMIH2C is a VME Bus Master Controller Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Control Systems. The communication link between the controller and the I/O boards, as well as the link to the IONet system control network, is provided by the VME Bus Master Controller (VCMI) board. The IDs for all the boards in the rack and their corresponding terminal boards are managed by VCMI, which is also the VME bus master in the control and I/O racks.
The IONet may link to various I/O racks, each of which has a VCMI board. Three simplex system setups using the VCMI with local and distant I/O are shown in the accompanying figure.
The first example is a compact system in which all of the I/O is mounted in the VME control rack, negating the need for any additional distant I/O racks. The VCMI features three IONet ports, with one for each of the three channels (R, S, and T).
A larger system with distant I/O racks makes up the second illustration. Although many I/O racks are supported by one IONet, only one rack is displayed here. Regarding I/O boards and points, all I/O channels (R, S, and T) are identical.
Frequently Asked Questions about IS215VCMIH2C
When was the IS215VCMIH2C and the Mark VI control system first released?
The Mark VI was one of the last of the Speedtronic lines to be released by GE. This line of gas/steam turbine management systems was developed in its various iterations from the late 1960s (the MKI) through the 1990s (the MKVI and MKVIe,) with the primary goal of increasing the efficiency of turbine systems through reliable management, good design, and the best of emerging technology. The IS215VCMIH2C was released during the production of the Mark VI Control System by GE Energy and GE Industrial Solutions.
Reviews For IS215VCMIH2C
The IS215VCMIH2C is an excellently designed bus master controller and is far better equipped than previous models of the VCMI modules such as the VCMIH1. The three IONet 10Base 2 Ports, up from the single port on previous models, makes this module ideal for TMR Systems. The additional status LEDs on the IS215VCMIH2C help the user to identify needed information. Highly rated turbine part
