| dbo:abstract |
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 / Drive Systems / HMI/SCADA 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) EGD is implemented using classes. * Class 0 - supports configured exchanges only (implemented in most PACSystems CPUs) * Class 1 - supports all class 0 services plus programmed EGD exchanges that can be used to read and write other devices on an ad-hoc basis * Class 2 - supports all class 1 services plus acts as a responder for programmed EGD exchanges (implemented by Ethernet interface module only) * Class 3 - supports all class 2 services plus static configuration from an EGD configuration server * Class 4 - supports all class 3 services plus dynamically bound configuration from an EGD configuration server (en) Ethernet Global Data (EGD) est un protocole de communication industriel entre automates programmables. Il a été initialement développé par GE Fanuc en 1998. Il utilise UDP comme couche de transport. Il utilise IP et Ethernet pour les couches inférieures, ce qui explique son nom. (fr) |
