Ethernet Powerlink is a deterministic real-time protocol for standard Ethernet. It is an open protocol managed by the Ethernet POWERLINK Standardization Group (EPSG). It was introduced by Austrian automation company B&R in 2001. This protocol has nothing to do with power distribution via Ethernet cabling or power over Ethernet (PoE), power line communication or Bang & Olufsens PowerLink cable. == Overview == Ethernet Powerlink expands Ethernet with a mixed polling and timeslicing mechanism. This provides: * Guaranteed transfer of time-critical data in very short isochronic cycles with configurable response time * Time-synchronisation of all nodes in the network with very high precision of sub-microseconds * Transmission of less timecritical data in a reserved asynchronous channel Modern implementations reach cycle-times of under 200 µs and a time-precision (jitter) of less than 1 µs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ethernet Powerlink」の詳細全文を読む スポンサード リンク
