PROFNET IO connection life-cycle : ウィキペディア英語版 | PROFNET IO connection life-cycle
The PROFINET IO connection life-cycle describes the connection between a PROFINET IO Controller and IO Device. The connection allows the cyclic exchange of process IO data, and the acyclic handling of alarms. The PROFINET IO connection life-cycle consists of address resolution, connection establishment, parameterization, process IO data exchange / alarm handling, and termination.〔PROFINET System Description, Version April 2009, PROFIBUS Nutzerorganisation e.V., 2009〕 == Address resolution == A PROFINET IO device is identified on the PROFINET network by its station name.〔The station name is a user-configurable alpha-numeric description of up to 240 characters〕 Connection establishment, parameterization and alarm handling are implemented with User Datagram Protocol (UDP), which requires that the device also be assigned an IP address. After identifying the device by its station name, the IO controller assigns the pre-configured IP address to the device.〔
