Ethernet Global Data
Ethernet Global Data (EGD) is a communications protocol developed by GE in 1998. Ethernet Global Data (EGD) allows a device (the Producer) to transfer data to other devices (the Consumers) on the network. Applications requiring high-speed networking and coordination from PLC to PLC (or PLC to GE Variable Frequency Drives) can take advantage of EGD. Ethernet Global Data is up to 10 times more efficient on bandwidth utilization than the normal polling system.
