The paper presents an original software library for the CompactRIO platform with embedded FPGA application that is used in LabVIEW projects. There are discussed the basic properties of NI RIO technology, hardware architecture of CompactRIO platform and the way of designing systems based on this controller. The use of it gives new didactic capabilities due to a combination of several areas of engineering which are programming the classical microcontroller and FPGA systems, signal processing, development of distributed systems or real-time measuring and distribution systems. The paper also describes the software library for LabVIEW environment and the way of using it in user programs, including student projects in the classes of the CompactRIO platform. It also presents a user library interface and a detailed description of it. The basic benefits of its application and the system architecture which can be realized with use of it are given. The use of the described library allows focusing on the issues directly related to the topic of taught subjects. During the implementation of the tasks set out in the paper, students acquire practical skills to design and run real-time systems. They also get experience in the use of advanced inter-process and network communications and become aware of their limits.
The National Instruments CompactRIO is an advanced embedded control and data acquisition system designed for applications that require high performance and reliability. This modular system has many new features like open embedded architecture, small size, small power consumption, extreme ruggedness, and flexibility. CompactRIO combines an embedded real-time processor, a high-performance FPGA, and hot-swappable I/O modules. Each I/O module is connected directly to the FPGA, providing low-level customization of timing and I/O signal processing. Full functionality of modular power quality analyzer formerly developed for PCbased instrument has been transferred to CompactRIO platform. This solution represents new level of technology for very flexible, powerful and robust power quality monitoring systems. In comparison with PC-based Power Quality Analyzer brings CompactRIO smaller size, lower power consumption and wide temperature range. Together with SW redesign needed because of HW platform change was developed new user interface concept with many revolutionary features.
