Example of PROFINET communication in the SIMATIC PCS 7process control systemIn the context of the SIMATIC PCS 7process control system, PROFINET mainly focuses on communicationbetween the automation systems (controllers) and the processI/O.Fieldbus systemsPROFIBUS has become established as sturdy andreliable communications medium for connecting intelligentdistributed I/O devices, transmitters and actuators to thecontroller level of the SIMATIC PCS 7 process control system.The universal, open fieldbus corresponds to the internationalstandards IEC 61158 and IEC 61784.Integration of PROFIBUSPA and FOUNDATION Fieldbus H1PROFIBUS DPPROFIBUS DP isboth a system bus and an open communication system, 西门子上海总代理商
and is designed for moderate transmission rates and short responsetimes. It is therefore optimally suitable for the control of thefollowing devices:Directly connected field devices, e.g. drives,motor starters, analyzers, process controllers, orpanelsDistributed I/O devices such as the SIMATIC ET 200M,SIMATIC ET 200iSP and SIMATIC ET 200pro remote I/OstationsTransmitters and actuators on a seamlessly integratedPROFIBUS PA fieldbus or FOUNDATION Fieldbus H1Since italso supports the transmission of the HART protocol, HART fielddevices can also be integrated in a PROFIBUS DP communicationnetwork.PROFIBUS PA and FOUNDATION Fieldbus H1In addition tothe direct connection of transmitters and actuators including powersupply via the communication medium, the high information contentof the communication as well as the diagnostic options are also ofimportance for the automation of industrial processes thatfrequently take place in corrosive, harmful, and hazardousenvironments.Both the PROFIBUS PA fieldbus and the FOUNDATIONFieldbus 西门子上海总代理商
|H1 meet these requirements. Both are optimally suitable fordirectly integrating actuators and sensors in operatingenvironments up to Ex zone 1/21 or 0/20 into the processsystem.Their physical bus characteristics are based on the MBPtransmission technology (Manchester Coded; Bus Powered) and arelargely identical according to IEC 61158. Both fieldbuses canbe integrated seamlessly in the SIMATIC PCS 7 process controlsystem using PROFIBUS DP as link.PROFIBUS PA andFOUNDATION Fieldbus H1 thus profit equally from thehigher-level PROFIBUS architecture.All about IndustrialcommunicationPresales InfoCatalog and ordering systemonlineTechnical infoSupportContact & partnersServiceoffers西门子上海总代理商
