![]() ![]() Typical applications can be found in infrastructure (e.g. ![]() This is why structured cabling or a wireless local area network for mobile subscribers can also be used. A manufacturer certificate is sufficient for the network infrastructure. In Conformance Class A (CC-A), only the devices are certified.Field devices in a subordinate Profibus line can be integrated in the Profinet system seamlessly via an IO-Proxy (representative of a subordinate bus system).Īpplications with Profinet can be divided according to the international standard IEC 61784-2 into four conformance classes: The Profinet protocol is designed for the fast data exchange between Ethernet-based field devices and follows the provider-consumer model. IO-Controllers are typically a PLC, DCS, or IPC whereas IO-Devices can be varied: I/O blocks, drives, sensors, or actuators. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosis. ![]() Its basis is a cascading real-time concept. It defines the communication with field connected peripheral devices. Profinet implements the interfacing to peripherals. 4.3.1 Management of the Application Relations (AR)įunctionalities Overview.
