Chapter 3 Deployment Manual VIPA System 200V3-2 HB97E - IM - RE_208-1DPx1 - Rev. 14/05Basics PROFIBUSPROFIBUS is an international standard applicable to an open fieldbus forbuilding, manufacturing and process automation. PROFIBUS defines thetechnical and functional characteristics of a serial fieldbus system that canbe used to create a low (sensor-/actuator level) or medium (process level)performance network of programmable logic controllers.Together with other fieldbus systems, PROFIBUS has been standardized inIEC 61158 since 1999. IEC 61158 bears the title "Digital data com-munication for measurement and control - Fieldbus for use in industrialcontrol systems".PROFIBUS comprises an assortment of compatible versions. The followingdetails refer to PROFIBUS DP.PROFIBUS DP-V0 (Decentralized Peripherals) provides the basicfunctionality of DP, including cycle data exchange as well as stationdiagnostic, module diagnostic and channel-specific diagnostic.PROFIBUS DP is a special protocol intended mainly for automation tasks ina manufacturing environment. DP is very fast, offers Plug'n'Play facilitiesand provides a cost-effective alternative to parallel cabling between PLCand remote I/O. PROFIBUS DP was designed for high-speed cyclical datacommunication between bus master and slave systems.The original version, designed DP-V0, has been expanded to includeversion DP-V1, offering acyclic data exchange between master and slave.DP-V1 contains enhancements geared towards process automation, inparticular acyclic data communication for parameter assignment, operation,visualization and alarm handling of intelligent field devices, parallel to cycleuser data communication. This permits online access to station usingengineering tools. In addition, DP-V1 defines alarms. Examples for differenttypes of alarms are status alarm, update alarm and a manufacturer-specificalarm.Please note in operating the DP V1 functionality that your DP mastersupports DP-V1 as well. For this you find details in the documentation toyour DP master.GeneralPROFIBUSDP-V0PROFIBUSDP-V1 |
