Ethernet Global Data (EGD) is a protocol that enables producer (server) to share a portion of its memory to all the consumers (clients) at a scheduled periodic rate. This protocol is developed for GE Fanuc PLCs to exchange data between PLCs / GE Drive Systems / GE HMI systems. The protocol uses UDP over Ethernet layers for exchanging the data. A snapshot of internal reference memory, mediated by an Ethernet interface, is referred to as an exchange. An exchange does not require a reply and is identified by a unique combination of three major identifiers. * The Producer ID (the producer's IP address) * The Exchange ID (the exchange's identifier) * The Adapter Name (the Ethernet interface identifier) ==External links== * (EGD Objectives ) 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 Global Data Protocol」の詳細全文を読む スポンサード リンク
