    en.wikipedia.org/wiki/SIMATIC

    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

  3. Instruction list - Wikipedia

    en.wikipedia.org/wiki/Instruction_list

    Many vendors whilst incorporating the full IEC 61131-3 requirements have additional vendor specific calls/function blocks to suit their hardware such as reading or writing to I/O. Siemens PLC instruction list language is known as "Statement List" or "STL" in English, and "Anweisungs-Liste" or "AWL" in German, Italian and Spanish.

  4. Programmable thermostat - Wikipedia

    en.wikipedia.org/wiki/Programmable_thermostat

    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.

  5. Smart thermostat - Wikipedia

    en.wikipedia.org/wiki/Smart_thermostat

    Most programmable thermostats also have a hold feature which suspends the schedule and effectively turns the thermostat into a manual thermostat. [5] The idea of the scheduling feature is that users will set a warmer or cooler temperature when the home is unoccupied to save energy and money.

  6. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    Siemens’ RTD rapidly fell out of favour due to the instability of the temperature reading. Hugh Longbourne Callendar developed the first commercially successful platinum RTD in 1885. A 1971 paper by Eriksson, Keuther, and Glatzel identified six noble metal alloys (63Pt37Rh, 37Pd63Rh, 26Pt74Ir, 10Pd90Ir, 34Pt66Au, 14Pd86Au) with approximately ...

  7. Planned obsolescence - Wikipedia

    en.wikipedia.org/wiki/Planned_obsolescence

    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.

  8. Compressed instruction set - Wikipedia

    en.wikipedia.org/wiki/Compressed_instruction_set

    In most real-world examples, compressed instructions are 16 bits long in a processor that would otherwise use 32-bit instructions. The 16-bit ISA is a subset of the full 32-bit ISA, not a separate instruction set. The smaller format requires some tradeoffs: generally, there are fewer instructions available, and fewer processor registers can be ...
