The issues of software and hardware development are considered of data logging into systems of testing complex objects. The describes the architecture of a system for testing complex scientific-technical objects. In the list of original elements of the concept of building highly reliable, fast-reconfigurable interactive test monitoring and control systems: — using of original technology of representation dynamic parameters of the current process of test management for the process to simplify the process of making reasonable and effective operational decisions; — using of classification analysis algorithms (for determining the periodicity in the study of the rhythmic structure of complex signals) that increase the informative of the parametric estimates obtained; — using of hierarchically detailed 3-D representations to the operator of the state of the control system and the object under test; — using of methods and algorithms for preemptive criterial adaptation for guaranteed preservation of controllability conditions and prevention of abnormal conditions; — using of the method of modeling the process of targeted selection and making decisions on the evaluation of test results, based on a structurally linked set of requirements for the characteristics of the evaluated objects. In the work, some aspects of the development of the interconnection of software and hardware for providing data logging during testing of complex objects, including for diagnosing and forecasting work processes with the purpose of preventing the development of emergency situations, are sketched out.
