All the operations of the control system (switching loads, speed control, etc.) and the surrounding technologies (heat pump compressors, electronics of poor-quality energy saving lamps, etc.) create interfering signals, which may adversely affect the quality of measurements of analogue values, decrease the quality of transmission on communication routes, reduce the lifetime of some elements, and sometimes even affect the stability of the entire application (communication failures, failures of some peripheral modules, or even failures of the control system basic module).
The following articles outlines the basic selected activities that increase the durability, reliability and lifetime of the whole intelligent installation, or the installation of the control system.
