 Durante todo el año recibimos muchos mail, pidiéndonos información para realizar trabajos sobre autómatas. Así que ahora es el momento para recordaros que necesitamos de vuestra colaboración enviándonos los que ya habéis presentado.




Physical Layer Flexibility

ControlNet's cost-effective performance is further enhanced by flexible installation options, widely available cable, and simple taps with no minimum spacing requirements.

bulletRG-6 quad shield cable, which is inexpensive and used widely in the cable TV industry
bulletPassive taps that can be installed anywhere on the trunk with no minimum spacing requirements
bulletSupport for bus, star, or tree topologies to meet various application needs
bulletOptional media redundancy that transparently allows higher system availability
bulletSupport for fiber optic cabling


ControlNet supports many topologies including Bus, Tree, Star and combinations using repeaters ().

   ControlNet uses inexpensive RG-6 quad shield cable. Network Taps provide flexible mounting options: "Y", "T", straight or right ended.
