IS420ESWAH1A Functional Description
The IS420ESWAH1A switch pack features eight 10/100Base-TX ports and one 100Base-FX LC-type connector, supporting two distinct mounting configurations. The switches can be mounted either perpendicular or parallel to the rail, with different clips provided depending on the chosen orientation. If mounted perpendicular, the required clip is the 259B2451BVP2. Though the IS420ESWAH1A is classified as an IONet Switch Module, it is not the original product for the Mark VIeS Series. That distinction belongs to the IS420ESWAH1 parent module, which doesn’t utilize the A-rated functional product revision found in the IS420ESWAH1A.
This IS420ESWAH1A Ethenet Switch 8 Port 1 Fiber device is housed in a robust metal box and features several Ethernet ports for seamless interaction with other Mark VIe and Mark VIeS Series products. The Mark VI PCB Board Assemblys IS420ESWAH1A’s LED indicators are designed with a factory-printed legend for easy diagnostics. Additionally, the device’s TB1 and TB2 ports are clearly labeled to guide users in identifying inputs and outputs.
To meet performance and functionality requirements, the GE Speetronic MKVI IS420ESWAH1A offers full/half duplex auto-negotiation, power LEDs, a 256 KB buffer, and support for up to 4,000 MAC addresses. The IS420ESWAH1A’s RJ45 connectors are designed for durability, withstanding up to 200 cycles of insertion and removal. A built-in switch facilitates flow control, ensuring that pauses are sent only when needed on a port. Comprehensive information on this IS420ESWAH1A can be found in manuals like GEH-6855 Volume I and II, GEH-6725 HazLoc, GEH-6861, and GEI-10089.

GE Gas Turbine Control System
The GE Mark VI system is a comprehensive control solution used primarily in power generation and other industrial applications. It controls, protects, and monitors gas and steam turbines, generators, and auxiliary systems.
The SPEEDTRONIC™ Mark VI turbine control is the current state-of-the-art control for GE turbines that have a heritage of more than 30 years of successful operation. It is designed as a complete integrated control, protection, and monitoring system for generator and mechanical drive applications of gas and steam turbines. It is also an ideal platform for integrating all power island and balance-of-plant controls. Hardware and software are designed with close coordination between GE’s turbine design engineering and controls engineering to insure that your control system provides the optimum turbine performance and you receive a true “system” solution. With Mark VI, you receive the benefits of GE’s unmatched experience with an advanced turbine control platform.
The heart of the control system is the Control Module, which is available in either a 13- or 21- slot standard VME card rack. Inputs are received by the Control Module through termination boards with either barrier or box-type terminal blocks and passive signal conditioning. Each I/O card contains a TMS320C32 DSP processor to digitally filter the data before conversion to 32 bit IEEE-854 floating point format. The data is then placed in dual port memory that is accessible by the on-board C32 DSP on one side and the VME bus on the other. In addition to the I/O cards, the Control Module contains an “internal” communication card, a main processor card, and sometimes a flash disk card. Each card takes one slot except for the main processor that takes two slots. Cards are manufactured with surface-mounted technology and conformal coated per IPC-CC830. I/O data is transmitted on the VME backplane between the I/O cards and the VCMI card located in slot 1. The VCMI is used for “internal” communications between:
■ I/O cards that are contained within its card rack
■ I/O cards that may be contained in expansion I/O racks called Interface Modules
■ I/O in backup <P> Protection Modules
■ I/O in other Control Modules used in triple redundant control configurations
■ The main processor card
Triple Redundancy
Mark VI control systems are available in Simplex and Triple Redundant forms for small applications and large integrated systems with control ranging from a single module to many distributed modules. The name Triple Module Redundant (TMR) is derived from the basic architecture with three completely separate and independent Control Modules, power supplies, and IONets. Mark VI is the third generation of triple redundant control systems that were pioneered by GE in 1983. System throughput enables operation of up to nine, 21-slot VME racks of I/O cards at 40 ms including voting the data. Inputs are voted in software in a scheme called Software Implemented Fault Tolerance (SIFT). The VCMI card in each Control Module receives inputs from the Control Module back-plane and other modules via “its own” IONet. Data from the VCMI cards in each of the three Control Modules is then exchanged and voted prior to transmitting the data to the main processor cards for execution of the application software. Output voting is extended to the turbine with three coil servos for control valves and 2 out of 3 relays for critical outputs such as hydraulic trip solenoids. Other forms of output voting are available, including a median select of 4-20ma outputs for process control and 0- 200ma outputs for positioners. Sensor interface for TMR controls can be either single, dual, triple redundant, or combinations of redundancy levels. The TMR architecture supports riding through a single point failure in the electronics and repair of the defective card or module while the process is running. Adding sensor redundancy increases the fault tolerance of the overall “system.” Another TMR feature is the ability to distinguish between field sensor faults and internal electronics faults. Diagnostics continuously monitor the 3 sets of input electronics and alarms any discrepancies between them as an internal fault versus a sensor fault. In addition, all three main processors
