FUNCTIONAL DESCRIPTION:
IS420UCSBH4A, REV G 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 UCSB controllers are stand-alone computers designed to run application code. They are panel-mounted and communicate with I/O packs via on-board IONet interfaces. IONet is a dedicated Ethernet network exclusively supporting Mark controls I/O modules and controllers. These controllers operate on QNX Neutrino, a real-time multitasking OS optimized for high-speed, reliable industrial applications. Unlike traditional controllers with backplane I/O, the UCSB controller does not host application I/O.
All I/O networks connect to each controller, ensuring access to all input data. The system's hardware and software architecture is designed to prevent the loss of application input even when a controller is powered down for maintenance or repair. The Mark VIeS UCSBSIA Safety Controller and Safety I/O modules support functional safety loops with SIL 2 and SIL 3 capabilities. These controllers and modules are tailored for safety-instrumented system (SIS) applications, enabling operators to manage critical safety functions and mitigate risks. The safety hardware and software are IEC 61508 certified for use in dedicated safety control applications. The UCSB Controllers offer the Following Advantages:
UCSB INSTALLATION:
The controller is housed within a single module that mounts directly to the panel's sheet metal. Dimensions for the module's envelope and mounting are provided in the diagrams below, with all measurements in inches. The UCSB must be secured to the panel as shown, ensuring vertical airflow through the fins is unobstructed.
UCSB SOFTWARE AND COMMUNICATION:
The controller is equipped with customized software capable of running rungs or blocks. Small adjustments to the control software can be made online without requiring a restart. The clocks of the I/O packs and controllers are synchronized within 100 microseconds using the IEEE 1588 protocol over the R, S, and T IONets. These networks also facilitate the exchange of external data with the control system database in the controller, including process inputs and outputs from the I/O modules.
UCSB BOOT LED:
During the boot process, the boot LED remains steadily lit unless an error occurs. In case of an error, the LED flashes once per second, staying lit for 500 milliseconds before turning off. After the flashing phase, the LED remains off for three seconds. The number of flashes indicates the specific error condition.
If the flash image is valid but the runtime firmware is not yet loaded, the boot LED flashes continuously at a steady rate until the firmware loads, at which point the LED turns off. Use the ToolboxST application to diagnose and resolve connection issues if the controller fails to come online. Once an IP address is assigned, the ToolboxST application configures itself via Ethernet.

What is the UCSB controller module used for?
The UCSB controller is a stand-alone computing system designed for high-performance industrial applications. It runs customized software to manage control and safety functions.
How is the UCSB controller module mounted?
It is mounted directly to the panel’s sheet metal. Proper installation requires ensuring unobstructed vertical airflow through the fins for cooling.
What operating system does the UCSB controller use?
It runs on QNX Neutrino, a real-time, multitasking operating system optimized for industrial reliability and performance.
How does the UCSB controller communicate with I/O packs?
It uses onboard IONet connections (R, S, and T), which are private Ethernet networks exclusively supporting Mark controls I/O modules and controllers.
