6-slot Military style, GigE Programmable Automation Controller (PAC) I/O Rack

Customizable & Deployed Sensor Interface Unit (SIU)
The Navy chose the UEI RACK form factor to replace the obsolete Sensor Interface Unit (SIU) on the Marine Landing Craft LCAC.

The UEIPAC 600-MIL is the latest deployment of UEI’s popular RACKtangle® architecture. It is basically a smaller version of UEI’s popular DNR-MIL and offers slots for six I/O boards rather than the DNR-MIL’s twelve. Designed for use in the toughest environments, the UEIPAC 600-MIL is ideal for military and aerospace deployments. It is also ideal for a huge assortment of commercial applications including oil drilling platforms and refineries, heavy machinery, outdoor test stands, and any other I/O application that will be exposed to the elements. All connectivity is through ROHS compliant 38999 connectors.

Electronically, the UEIPAC 600-MIL is identical to the standard DNR Series RACKtangle except for hold-up and protection circuitry on the power supply inputs to meet MIL-STD-1275/704). This means the UEIPAC 600-MIL uses standard DNR-series boards (e.g. DNR-AI-217 or DNR-1553-553). With 90+ unique I/O boards and 6 slots available there’s sure to be a configuration matching your application.

The new UEIPAC 600-MIL is designed to meet the most commonly required elements of MIL-STD-461 and -810 and is sealed to at least IP66/NEMA6 standards. All this is housed in a compact 11.6" (wide) x 7.0" (tall) x 6.4" (deep) chassis, weighing approximately 16 pounds and typically consuming less than 30 Watts. Heat transfer from the internal electronics to the external chassis is designed such that no fans or rotary cooling is required. The lack of fans maximizes MTBF and mechanical reliability. All internal printed circuit boards are conformal coated to ensure the highest reliability. Heat sink style fins on the top and bottom of the unit ensure the unit will meet its temperature specifications without any forced air cooling, though the unit is also suitable for use with a cold plate if appropriate.

The UEIPAC is an embedded standalone system – supporting both VxWorks and Linux – that runs your application. It's quick to install the PAC and run your first program. Precompiled examples are provided. Your Linux/ VxWorks application runs directly on the UEIPAC. There is no need for a separate host PC, though you can certainly connect one in a monitoring or supervisory role. This allows smaller, faster, more reliable, and higher performance systems. It also eliminates the cost of a dedicated host PC and guarantees long-term availability of the identical hardware. This is critical when certifying products through CE. In this mode, the DNR-MIL-6 can run fully stand-alone or may be linked to a SCADA host via the Ethernet.

LINUX Deployments

Your application runs as a regular Linux process giving you access to the standard POSIX API provided by the GNU C runtime library (glibc) as well as any other library that can be compiled for Linux (for example: libxml, libaudiofile…). We also support the Linux_rt preempt patch for real-time support.

To develop programs for the UEIPAC, you will need to purchase a copy of the UEIPAC Linux TK programmers toolkit. The toolkit provides the various items needed to write applications for the UEIPAC. Regardless of the number of cubes you deploy, you need only purchase one programming toolkit. UEIPAC is an embedded Linux-based system with no graphical interface. It is very good at network connectivity, which makes it possible to create remote graphical user interfaces (also known as HMI Human-Machine-Interface).

VxWorks Deployments

You may now take advantage of all the hardware advantages of UEI's popular UEIPAC chassis and continue to develop your applications in VxWorks. This powerful combination provides hard real-time performance, an extremely robust and reliable operating system, allows you to develop your application in a familiar environment and last, but not least, allows you to preserve a great deal of previously written code! To deploy a UEIPAC application running VxWorks you'll need the following.

1. A UEIPAC (any version)
2. The "UEIPAC VxW BSP". You only need to purchase the BSP once, regardless of the number of systems you deploy
3. A VxWorks development system (from Wind River)
4. A VxWorks run-time license for each UEIPAC deployed. (also purchased from Wind River )

Additional information on UEI and UEIPAC can be found in our Software Support section.

The MIL-600 chassis is available in different deployment options including: PowerDNA, PAC (Programmable Automation Controller), Simulink Coder Target, Modbus TCP Interface and OPC Unified Architecture Interface.

Mathworks Embedded Coder® & UEI Solutions

Mathworks Embedded Coder® generates readable, compact, and fast C and C++ code for embedded processors used in mass production. Embedded Coder is available for use on UEIPAC and UEISIM systems. The choice of Embedded Coder versus Simulink Coder is done when selecting the system target file (same as what you would do to select PowerPC, SoloX ARM, or Zynq UltraScale+ CPU targets).
