IS200SAIIH2A IS200SAIIH2A IS200SAIIH2A America (NEMA) gave him a new Programmable Controller, or PC. In 1982, the International Electrotechnical Commission (IEC) specifically for programmable controller under the strict definition. However, PC this abbreviation name has already become a synonym of Personal Computer (Personal Computer) in China, in order to avoid confusion of terminology, so the abbreviation…
