Functional Description

The IS215UCVEH2AF is a VME board developed by GE. It is part of the Mark VI control system. This single-slot VME (Versa Module Eurocard) board plays a vital role in the operation of the control system. The system utilizes a 300 MHz Intel Celeron microprocessor with 32 MB of DRAM memory. It offers flexibility between 16 MB or 128 MB compact flash modules. In addition, the system includes a 128 KB L2 cache for faster data access. To support the controller functions, an 8K battery-powered SRAM is allocated for use as the NVRAM in the system architecture.

Primary Ethernet Interface (Ethernet 1)

The primary Ethernet interface (Ethernet 1) on this system has the following specifications:

Connection type: Twisted pair 10BaseT/100BaseTX technology and RJ-45 connectors allow for a variety of connection options.

Communication protocol: TCP/IP protocol: Primarily used for communication between the controller and the toolbox, ensuring seamless data exchange within the system.

EGD Protocol: Designed to communicate with CIMPLICITY HMIs and 90-70 series PLCs (Programmable Logic Controllers), facilitating efficient and reliable data transfer.

Ethernet Modbus Protocol: Supports communication between the controller and third-party DCS (Distributed Control System), providing compatibility and integration across different systems.

COM ports

The system contains two miniature 9-pin D connectors dedicated to COM ports:

COM1: Function: Dedicated for diagnostic purposes, maintains a baud rate of 9600 with data configuration set to 8 data bits, no parity and 1 stop bit.

COM2: Purpose: Dedicated for serial Modbus communication, supports variable baud rates of 9600 or 19200. This port facilitates efficient and reliable communication of Modbus related data transactions.

Part of the Mark VI GE Speedtronic series, the GE Mark VI IS200TRPLH1A is used as a primary trip terminal board.

General Electric’s IS200TRPLH1A board assembly is used in the company’s Mark VI system for conditioning industrial gas and steam turbine systems.

The Mark VI was one of the last Speedtronic systems developed and released by General Electric.

This board is typically found only on steam turbines. It is compatible with the Mark VI and Mark VIe systems.

It is the terminal card for the primary stroke on large steam turbines. It is the primary overspeed protection on large steam turbine systems.

The board is controlled by the Turbine Protection Controller card, which is usually a VTUR or PTUR board.

It also works in conjunction with the TREL board to provide an emergency/primary interface to the ETD.

The TRPL board feeds the negative side of the 125 VDC to the trip solenoid, while the TREL board provides the positive side. Up to three trip solenoids can be connected to these boards.

The boards have two large terminal blocks with a total of 48 connector points.

Also included are MOV diodes, resistors, transistors, integrated circuits, jumpers, and nine magnetic relays, as well as 3D housing connectors and other plug connectors.

Three voting circuits are connected via relays to three trip solenoids.

The trip circuits include solenoid suppression and voltage monitoring, and the solenoids vote using two-thirds contacts.

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.
