To serve expanding machine and industrial control system development needs, leading automation companies have created a new class of industrial controllers known as programmable automation controllers (PACs).
The National Instruments PAC architecture is comprised of NI LabVIEW, a graphical programming language running on one of five PAC hardware deployment platform real-time OSs. LabVIEW offers you the flexibility to create complex measurement and control systems while providing ease of use through an intuitive graphical interface. With LabVIEW, you quickly can develop complex programs using hundreds of built-in control and analysis functions. You also can call code developed in other packages such as LabWindows/CVI, C, or The MathWorks, Inc. Simulink, and perform I/O, motion control, machine vision, and communications. With this architecture, National Instruments provides you with more I/O capabilities, more deployment choices, and the most comprehensive software environment for performing measurement and control.
National Instruments PAC architecture gives you the power to:
- Create custom and advanced measurement and control systems
- Integrate sophisticated processing functionality into existing automation systems
- Design rugged, reliable machine control and OEM production systems
NI PAC Hardware:
Compact FieldPoint is an easy-to-use, highly expandable programmable automation controller (PAC) composed of rugged I/O modules and intelligent communication interfaces. Download your National Instruments LabVIEW application to the embedded controller for reliable, stand-alone operation and connect your sensors directly to high-accuracy analog and discrete I/O modules. These industrial I/O modules filter, calibrate, and scale raw sensor signals to engineering units and perform self-diagnostics to look for problems, such as an open thermocouple. Compact FieldPoint network communication interfaces automatically publish measurements with an Ethernet network. You can access I/O points nearby or miles away on the network using the same simple read/write software framework.
NI Compact Vision System (CVS): For machine vision and simple control applications, deploy your National Instruments LabVIEW application on the NI CVS . The NI Compact Vision System extends the power of NI LabVIEW Real-Time to a rugged machine vision package that withstands harsh environments common in industrial inspection.
Using IEEE 1394 (FireWire) technology, the Compact Vision System is compatible with more than 100 industrial cameras with a wide price, functionality, and performance range. With three IEEE 1394 (FireWire) ports, you can make multicamera inspections with up to 16 cameras. Also, the Compact Vision System offers reconfigurable I/O FPGA for high-speed custom digital control or stepper motor control.
PXI is a multivendor industry standard based on CompactPCI architecture. PXI is ideal for mid- to large-size applications because it delivers a modular PC-based platform for both National Instruments and third-party CompactPCI and PXI plug-in modules. PXI offers the widest range of I/O, including 1000 V isolated analog input, high-density digital I/O, analog and digital image acquisition devices for machine vision, and coordinated multichannel motion.
PXI is easy to use, with support for both Windows and real-time applications. For industrial applications, PXI offers extended (0 to 55 °C) operating temperatures, defined cooling (25 W per slot) and power requirements, and extended shock and vibration specifications. Defined cooling and power specifications ensure that the PXI platform supports a wide range of modular I/O. PXI is a rugged platform with integrated backplane synchronization for applications such as vision-guided motion control and high-channel, phase-synchronous measurements.
NI PAC Software:
NI LabVIEW is a graphical development environment that delivers unparalleled flexibility and ease of use in demanding industrial measurement, automation, and control applications. With NI LabVIEW, you quickly create user interfaces for interactive software system control. To specify system functionality, simply assemble block diagrams and use the intuitive LabVIEW graphical development paradigm to create deterministic control applications that you can deploy as distributed or stand-alone systems. LabVIEW makes it easy to construct simple or complex applications using an extensive palette of functions and tools - from simple analog PID process control loops to high-channel-count hybrid control systems.
HOW DOES IT WORK? Each LabVIEW Real-Time hardware target has a dedicated processor running a real-time OS for reliability, stability and determinism. By adding the LabVIEW FPGA Module to the LabVIEW environment, you can create code that runs directly on an FPGA chip for ultrahigh performance and custom timing. Use the LabVIEW platform for your industrial measurement, automation, and control applications by following these three steps:
- Choose your I/O - LabVIEW delivers access to the widest selection of I/O, from data acquisition, motion control, and vision integration to machine vision and custom-designed I/O from a single environment.
- Choose your analysis or control methods - With more than 450 LabVIEW analysis and control functions, you define your system to your specific requirements.
- Choose your real-time deployment platform - Once you create your LabVIEW application, deploy it to run deterministically on the hardware platform you choose.
