The IS420UCSBH4A is a controller module manufactured by General Electric as part of the Mark VIe family.

for gas turbine control systems with 1066 MHz Intel EP80579 microprocessors.

The application code is executed by a separate computer called the UCSB controller.

The controller is panel mounted and communicates with the I/O packages through an on-board 1/0 network (IONet) interface.

Only Mark controls the I/O modules and the controller, supported by a dedicated private Ethernet network called IONet.

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

The UCSB controllers lack any application I/O hosts compared to traditional controllers that host application I/O on the backplane.

In addition, each controller has access to all I/O networks for all input data.

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

Functional safety loops are implemented using Mark VIeS UCSBSIA safety controllers and Safety 2/3 modules for SIL 1 and 0 functionality.

Operators familiar with SIS applications use Mark Vles safety devices to reduce the risk of critical safety functions.

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

UCSB controllers offer the following benefits:

Single module

Built-in power supply

No jumper settings required

No batteries

Fanless (UCSBSIA, UCSBHIA, UCSBH4A)

Dual redundant fans with IS420UCSBH3A

Smaller panel footprint

Flash memory can be easily updated

UCSB Mounting:

Individual modules mounted directly to the panel sheet metal contain the controller. Dimensions of the module enclosure and mounting are shown below.

Each measurement is in inches. the UCSB must be attached to the panel as shown. vertical airflow through the fins remains unobstructed.

The following communication ports provide links from the Mark VIe controller to the I/O operator and engineering interfaces.

UCSB Software and Communications:

Software customised for controller use is installed. Stages or blocks can be run from it. Minor changes to the control software can be made on-line without rebooting.

Synchronises 1588/O packets and the controller's clock within 100 microseconds using IEEE 1 protocol via R, S and T IONet.

External data is sent to and received from the control system database in the controller via the R, S and T IONet.

This includes the process inputs and outputs of the 1/0 modules.

In addition, in a two-rail system these are:

1. from the selected controller

Data from the selected controller's initialisation and internal state variables 2. Information about the synchronisation and state of the two controllers

This also includes the following in a Triple Modular Redundancy (TMR) system:

Information about the synchronisation, polled internal state values and status of all three controllers

Initialisation data from the selected controller

UCSB boot LED:

If there are no errors, the boot LED will remain lit throughout the boot process. If an error is detected, the LED will flash once per second (Hz).

The LED flashes for 500 milliseconds and then goes out. The LED remains off for three seconds after the flashing phase. The flash count indicates a fault condition.
