DESCRIPTION:

IS420UCSBH4A is a UCSB Controller Module manufactured by General Electric as part of the Mark VIe Series used in gas turbine control systems with a 1066 MHz Intel EP80579 microprocessor.

The application code is executed by standalone computers called UCSB controllers. 

Through onboard 1/0 network (IONet) interfaces, the controller mounts in a panel and communicates with the I/O packs.

Only Mark controls I/O modules and controllers are supported by the private, special-purpose Ethernet network known as IONet.

The controller's operating system (OS) is QNX Neutrino, a real-time, multitasking OS developed for industrial applications requiring great speed and dependability.

The UCSB controller lacks any application I/O hosts, in contrast to conventional controllers that host application I/O on a backplane.

Additionally, each controller has access to all I/O networks, providing them with all input data.

If a controller is turned down for maintenance or repair, the hardware and software architecture ensures that no single point of application input is lost.

Functional safety loops are implemented to achieve SIL 2 and 3 capabilities using the Mark VIeS UCSBSIA Safety controller and Safety 1/0 modules.

Operators who are familiar with SIS applications employ Mark Vles Safety equipment to lower risk in crucial safety functions.

These particular control hardware and software have IEC 61508 certification and are specifically configured for work with safety controllers and distributed I/O modules.

The UCSB Controllers offer the Following Advantages:

ü Single module

ü Built-in power supply

ü No jumper settings required

ü No battery

ü No fan (UCSBSIA, UCSBHIA, UCSBH4A)

ü Dual-redundant fans with IS420UCSBH3A

ü Smaller panel footprint

ü Flash memory can be conveniently updated

UCSB SOFTWARE AND COMMUNICATION:

Software customized for the controller's use is installed.

Rungs or blocks can be run by it. Without needing to restart, small changes to the control software can be done online.

The clocks of the 1/O packs and controllers are synchronized to within 100 microseconds using the IEEE 1588 protocol via the R, S, and T IONets.

Through the R, S, and T IONets, external data is sent to and received from the control system database in the controller.

This comprises the 1/0 modules' process inputs and outputs.

Additionally, in a dual system, these are:

1. Data on initialization and internal state variables from the selected controller

2. Information on the synchronization and status of both controllers

This also covers the following in a triple modular redundant (TMR) system:

Information on synchronization from all three controllers, internal state values for voting, and status Initialization data from the chosen controller
