The functions of the water level control system in the steam generator are distinguished. It is proposed to consider two control phases in normal operation and protection control modes. The automation system sets priorities for the operation of the steam generator level stabilization and over-protection control systems, which are considered as basic properties of signals. The signal model is considered as a combination of sets of a basic property description, an extended property description, and a set reflecting the specifics of the unified means application. The first set includes parameter name, current value, time stamp, priority, upd ate and validity signs, se t point, change range boundaries. Extended set includes number of GET-plan, addressing of communication module for signal transmission, hysteresis for set point, list of events in case of deviations in control problem solution. Properties related to TPTS using are sign of presence of general type interference, freely designed feature, error in memory, power supply failure, ADC failure.
