SIMATIC is a series of programmable logic controller and automation systems, developed by Siemens. Introduced in 1958, the series has gone through four major generations, the latest being the SIMATIC S7 generation. The series is intended for industrial automation and production. The name SIMATIC is a registered

Continuous obsolescence or perpetual revolution is a phenomenon where industry trends, or other items that do not immediately correspond to technical needs, mandate a continual readaptation of a system. Such work does not increase the usefulness of the system, but is required for the system to continue fulfilling its functions.
Sloan often used the term dynamic obsolescence, [10] but critics coined the name of his strategy planned obsolescence. This strategy had far-reaching effects on the automobile industry, product design field and eventually the whole American economy. The smaller players could not maintain the pace and expense of yearly re-styling.
Honeywell electronic thermostat in a store. Heating and cooling losses from a building (or any other container) become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.
Obsolescence is the process of becoming antiquated, out of date, old-fashioned, no longer in general use, or no longer useful, or the condition of being in such a state. When used in a biological sense, it means imperfect or rudimentary when compared with the corresponding part of other organisms.
It is otherwise identical in operation to the earlier type. Many cars of the 1950s, or earlier, that were originally built with bellows thermostats were later serviced with replacement wax capsule thermostats, without requiring any change or adaption. This most common modern form of thermostat now uses a wax pellet inside a sealed chamber. [6]
A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
