Anintelligent control device requires connection to configuration and monitoring tools,operator interfaces, and other peripheral devices, as well as the option to connect to avariety of industrial fieldbusses. At the same time, the intelligent devices continue toshrink in size and cost, forcing distribution of the field connections that once were nativeon the devices.QCPort is a flexible interface port that integrates the many connectivity needs of theintelligent device into a single device port for the means of control, setup, andconfiguration. The integration of these capabilities provides interface options that arepowerful and cost effective. In addition to the interface functionality of QCPort, care hasbeen taken to insure that systems that connect via QCPort are simple to configure,connect, and maintain.QCPort Physical CharacteristicsIn an effort to use existing proven technology, QCPort uses the RS485 physical layer.This physical layer is common to many industrial communication interfaces and has along and proven track record within industrial applications. QCPort is a four-wire systemwhere there is an A and B for signal and a +DC and Ground for device power.Depending on the type of device interconnect and the distance between devices, thereare many choices for the type of interconnect physical media; these choices will bediscussed further in the manual.
