4 Deployment4.1 Basics PROFINETn PROFINET is an open Industrial Ethernet Standard from PROFIBUS & PROFINETInternational (PI) for automation.n PROFINET is standardized in the IEC 61158.n PROFINET uses TCP/IP and IT standards and supplements the PROFIBUS tech-nology for applications, where fast data communication with industrial IT functions isdemanded.There are 2 PROFINET function classes:n PROFINET IOn PROFINET CBAThese may be realized in 3 performance steps:n TCP/IP communicationn RT communicationn IRT communicationn With PROFINET IO an I/O data sight to the distributed periphery is described.n PROFINET IO describes the whole data transfer between IO controller and IO device.n PROFINET is configured like PROFIBUS.n PROFINET IO always contains the real time concept.n Contrary to the master-slave procedure of PROFIBUS, PROFINET uses the provider-consumer model. This supports the communication relations (AR = Application Rela-tion) between equal participants in the Ethernet. Here the provider sends its datawithout a request of the communication partner.n Apart from the user data exchange also functions for parametrization and diagnosticsare supported.n PROFINET CBA means Component Based Automation.n This component model describes the communication between autonomously workingstations.n It makes a simple modularization of complex plants possible, by distributed intelli-gence by means of graphic configuration for communication of intelligent modules.This is the open communication via Ethernet TCP/IP without any demand on real-time.n RT means Real-Time.n The RT communication represents the basics for data transfer at PROFINET IO.n Here RT data are handled with higher priority.n IRT means Isochronous Real-Time.n With the IRT communication the bus cycle begins clock-exactly i.e. with a maximumpermissible tolerance and is again synchronized. Thereby the time-controlled andsynchronous transfer of data is guaranteed.n Here sync telegrams of a sync master in the network serve for.GeneralPROFINET IOPROFINET CBATCP/IP communicationRT CommunicationIRT CommunicationVIPA System SLIO DeploymentBasics PROFINETHB300 | IM | 053-1PN00 | en | 19-08 45
