Abstract: The article presents the design and construction of data acquisition module, which allows read and write data counted by the data acquisition board. The acquisition was controlled using a program that was created in the QNX Momentics development environment, based on the architecture of the RLP. It involves the measurement card control directly by the read and write to memory registers. Data acquisition was performed on a computer running a hard real-time system QNX6 Neutrino. With the use of available tools QNX Neutrino RTOS was realized network communication process for managing production data in a distributed system. The article presents also industrial networks such as Profibus and Ethernet. Discusses the characteristics of distributed systems and the requirements for real-time systems.
