The presented paper introduces an information technology for reconfiguration of the system based on programmable logic integrated circuits for wireless sensor network control module. The developed information technology allows changing configuration of sensor network (add, delete, change current settings, etc.) without additional activities on the software description level. This technology makes a system more universal and makes possible data processing for different wireless technologies that can be performed without reset of the whole system. The proposed approach is based on the fact that modules can be substituted immediately during their work in real time mode. Additionally, implementation of such modules has to follow constraints from the point of view of the internal infrastructure of the circuit. It is presumed that the controller module manages states of processing modules and interface module and ensure capability of loading firmware into specific regions of the programmable logic device. Control over the available firmware versions is also a responsibility of the controller. This way, additional level of abstraction is provided to communicate with external modules and to reduce dependency from the connection interface. As a result, flexibility of the system will be increased alongside with provision of the uninterruptable work of the whole system. This is the main difference and benefit of the devised solution in comparison with available technologies. The solution is specifically important for wireless sensor network as they can change configuration of the end-node modules and that process entails changes in all processing elements.
