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.
Message Data Interface (MDI)
The industrial market applies a range of wired and wireless communication technologies ranging from licenses band radio communications to serial busses to open Ethernet standards. The predominant communication technologies are as follows:
- Serial (e.g., RS-232, RS-485, Universal Serial Bus (USB))
- Controller Area Network (CAN)
A vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer.
- Personal area networks (e.g., low power wireless mesh such as IEEE 802.15.4, or Bluetooth IEEE 802.15.1)
A computer network used for data transmission amongst devices such as computers, telephones, tablets and personal digital assistants.
- Local area networks (e.g., Ethernet (IEEE 802.3) and WiFi (IEEE 802.11))
A computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building and has its network equipment and interconnects locally managed
- Wide area networks and beyond (e.g. WiMax, cellular, satellite and others)
A telecommunications network or computer network that extends over a large geographical distance
