　　Controller IS420UCSBH4A was designed by General Electric for the Mark VIe series to be used in high-speed applications, with a 1066 MHz EP80579 Intel Processor. This controller can be used in EX2100e and LS2100e applications along with the Mark VIe series.

　　Product Description

　　Controller IS420UCSBH4A is another UCSB controller produced by General Electric for the Mark VIe Series. This controller is described as being able to work in the EX2100e, LS2100e, and Mark VIe series that operate on a 1066 MHz EP80579 Intel Processor. The EP80579 processor is used to help in applications that require high reliability as well as high speeds. This model is similar to the previous UCSB controllers except for the processor used which is mentioned above, the controller all use the same processor type but operate on a different MHz.

　　The IS420UCSBH4A controller is similar to the UCSC controller that is also in the Mark VIe Series, the difference between the group of controllers is the hardware, but they do have some similarities pertaining to the advantages of the controller. Some of the advantages of this controller are that is a single module and it has flash memory which can be conveniently updated for the user's needs. The locations and the certifications needed to operate this controller are the same as the previous models, the controller can be used in hazardous and non-hazardous locations with UL E207685 and UL DEMKO 12 ATEX 1114875X certifications. All information regarding the locations and their required certifications can be obtained from the GEH-6725 Mark VIe/VIeS Controls Equipment HazLoc Instruction Guide on page 112.

　　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:

　　Single module

　　Built-in power supply

　　No jumper settings required

　　No battery

　　No fan (UCSBSIA, UCSBHIA, UCSBH4A)

　　Dual-redundant fans with IS420UCSBH3A

　　Smaller panel footprint

　　Flash memory can be conveniently updated

　　UCSB INSTALLATION:

　　A single module that installs directly to the sheet metal of the panel contains the controller. The dimensions for the module envelope and mounting are shown in the diagrams below. Every measurement is in inches. The UCSB must be attached to the panel as depicted, with the vertical airflow through the fins remaining unhindered.

　　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

　　UCSB BOOT LED:

　　In the absence of a mistake, the boot LED remains on throughout the boot process. The LED will blink once per second (Hz) if an error is found. The LED blinks for 500 milliseconds, then goes off. The LED stays off for three seconds after the flashing phase. Flash count reveals failed condition.https://www.axcontroler.com/Product/

　　The boot LED flashes continuously at a Hz rate if the flash image is genuine but the runtime firmware has not yet been loaded. The firmware loads and the boot LED goes off. Use the ToolboxST app to find out why the controller is blocked if it won't connect online. After receiving an IP address, ToolboxSTplication configures itself over Ethernet.
