FS-8704-12_GE-EGD Manual Page 3 of 26 1. GE-EGD (Ethernet Global Data) Description The GE-EGD (Ethernet Global Data) driver allows the FieldServer to transfer data to and from devices over Ethernet using GE-EGD (Ethernet Global Data) protocol. There are two Ethernet ports standard on the FieldServer. The FieldServer can emulate either a Server or Client. GE Fanuc Automation and GE Drive Systems developed an Ethernet Global Data, or EGD, exchange for PLC and computer data in

Recently producer-consumer model protocols have started to become more numerous. The GE-EGD (Ethernet Global Data) is a producer-consumer model protocol. In equating the two models it is important to regard the consumer as a passive (FieldServer) client. Other clients typically are active and poll for

Use Versapro to configure/look at the EGD configuration. Produced data must be produced for a specific consumer. Thus you must create a new exchange in the PLC that will produce data for the FieldServer. (Specific consumer means specific IP address). Since the EGD data packet is not structured, the FieldServer cannot decode the

Typically it will be the same as the IP of the closest GE Ethernet port. You can override this. • Add Ranges. Record the offset and reference for each data range in the exchange. • Save your work. • Close HWC. • Stop the processor. • Store the Hardware settings to the PLC • Put the processo
