Function Modules

NAI Configurable Open Systems Architecture™ (COSA®) allows for a rapid ‘off-the-shelf’ configuration of NAI’s multifunction I/O boards and systems. Our motherboards and systems are designed for smart functions to interface with various analog, digital, and communications sensors and devices. A tailored I/O and communications solution is easily obtained by mixing and matching field-proven smart function modules and their associated modular software, which are already used by hundreds of customers. Choose from over 100 I/O, Measurement and Simulation, Communications, and Storage modules.

All of our smart function modules are supported in NAI’s Software Support Kits, where the function module libraries or application programming interface (APIs) are simply managed for the software engineer. By providing a common modular API structure, accessing individual registers on a specific smart function module is as easy as passing a board slot number, module slot number, channel number and data parameter(s) into an API function.

Integration

Each smart function module is designed and tested independently for reliable integration into the control system as needed. APIs also provide a standardized interface that other applications can use to control the system, allowing developers to choose their preferred programming language, tools, and libraries. Developers can build more complex and sophisticated multiple-component systems.

Ease of Use

All smart function modules share common template APIs, which abstract away the complexity of the system. These APIs present a simple and intuitive interface that developers can use to control the system's behavior. This creates similarity and programmability across all modules, leading to a more I/O-intensive, distributed, and cost-effective mission system.

Performance

The dedicated System-on-Chip (SoC) on each function module supports customizable application and FPGA code for embedded real time combined functions, such as programmable PID loop support. In systems where real-time responsiveness is essential, these dedicated SoCs provide high-speed and low latency processing, while also optimized for low power consumption.

Efficiency

Memory map-based configurability allows for efficient use of resources such as memory and processing power. By using the API functions to modify values stored in memory-mapped registers, the system can adjust its use of resources based on the current operational requirements, eliminating the need for additional hardware and reducing overall cost.

Reliability

Most smart function modules perform built-in (and continuous) self-tests and diagnostics to detect and flag faults or errors in the module's operation including potential external influences such as faulted or shorted wiring. This allows for a high level of fault tolerance.

Maintainability

Standard COSA smart modules and APIs provide board or system level factory reconfigurability and obsolescence protection. They shield developers from changes to the system's underlying implementation and future technology upgrades. You can respond to evolving design specifications with reduced NRE (non-recurring engineering) charges.

For more control beyond the API, we offer the ability to directly control our modules via memory map registers. As opposed to driver-centric command/control, the smart function modules are memory mapped to the motherboard via a high-speed SerDes module interface, without undue processing overhead.

Chip Detector and Fuzz Burn

NAI's chip detector smart function modules are a magnetic-electrical device that provides a reliable method of detecting impending failure of bearings and gears and intended to be used as a maintenance time gauge or flag risk of imminent mechanical subsystem failure. As ferrous metallic particles are attracted to the sensor and begin to bridge the gap between the two contacts, the chip sensor circuit detect resistance drops. NAI's chip detection smart function modules continuously measures the sensor gap resistance and when the sensor gap resistance falls below the programmable FAULT resistance threshold, the Fuzz Burn charge circuit is triggered (programmable, up to 10x attempts) to ‘burn-off’ normal and typical amounts of metallic sludge (fuzz).

AC Reference

NAI’s AC Reference smart function modules are used to provide an AC signal source for synchro, resolver LVDT and RVDT devices. All synchro, resolver, LVDT, and RVDT measurement and simulation smart function modules use transformers whose main primary-to-secondary coupling is varied by physically changing (or, in simulation, commanding) the relative orientation of the two windings. For operation, the primary winding of these transformers is excited by an alternating current, and electromagnetic induction causes current to flow in the secondary winding. Windings are fixed at certain characteristic electrical angles to each other on the stator. NAI offers three smart function modules that provide an AC signal source when a secondary reference source other than the optional on-board reference module is required. The modules are programmable for full range voltage outputs from 2 to 115 VAC, and frequency from 47 Hz to 10 kHz.

IRIG Timecode Receiver and Generator

NAI's IRIG smart function module synchronizes to IRIG-A/B/G time codes and provide precise time in a memory register for NAI single board computers. The IRIG output of the module can be used to synchronize other IRIG time code readers. Additionally, the IRIG smart function module includes a real-time clock (RTC) that may be used as a reference for IRIG master applications, freeing the system processor from the task of updating the master timer. The output format of the module is independent from the incoming IRIG signal, providing a convenient solution for IRIG conversion applications. The most common format is IRIG-B, but the module can be designed to support IRIG-A and IRIG-G as well.

LVDT RVDT Measurement and Simulation

A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement. Both deliver signals proportional to the linear displacement of the moveable core. NAI offers five smart function modules that convert these signals to a digital output corresponding to position in a variety of operating parameters. An LVDT/RVDT simulator is used to convert digital positional commands to corresponding AC signals.

Strain Gauge Measurement

While there are several methods of measuring mechanical strain, the most common is with a strain gauge. The gauge provides electrical resistance that varies in proportion to the amount of strain in the device. The most widely used gauge is the bonded metallic strain gauge. To measure such small changes in resistance, strain gauges are almost always used in a bridge configuration with a voltage excitation source. The general Wheatstone bridge (conventional, 4-arm bridge) consists of four resistive arms with an excitation voltage, Vexc, that is applied across the bridge. NAI's strain gauge smart function module uses four independent, isolated input A/Ds. This module is designed to read output signals from a completed Wheatstone bridge (i.e., it can be used with one or more strain gauge elements as a completed 4-arm Wheatstone bridge) and is commonly used in applications requiring pressure, weight, and stress transducers interface/measurement.

Synchro Resolver Measurement and Simulation

Synchros and Resolvers are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals. NAI offers five smart function modules that cover the range of excitation voltages/frequency, include extensive field-parameter programmability, and provide a full operating envelope choice for interfacing to virtually any type Synchro or Resolver.
