The industrial market vertical is characterized by three prevailing application areas – discrete, continuous, and hybrid applications.

  • Discrete applications are often referred to as factory automation or factory systems. The output of discrete operations are individual pieces or “discrete parts,” often manufactured in machines that stamp, form, cut, print, mold, and/or package the raw materials into usable or sellable parts.
  • Continuous applications convert raw materials into usable or sellable product through, most often, chemical transformations without interruption. The product has no measureable beginning or end and is constantly being produced.
  • Hybrid applications are combinations of discrete and process operations.  Batch processing is a good example of a hybrid process.  In batch processing, discrete amounts of materials are loaded into a vessel or similar piece of equipment, combined together as a mixture or with a catalyst to generate a chemical reaction, and then discharged from the vessel as a usable or sellable product.  Hybrid applications are often combined with discrete applications to create products such as bottled or canned beverages, food products, pharmaceuticals, and similar packaged goods.
