165361 Rev. JDescription
The 3500/91 EGD (Ethernet Global Data) Communication
Gateway modules provide comprehensive communication
capabilities of 3500 rack-monitored values and status. This
Ethernet network path provides information with response
times suitable for controller applications. Using the 3500/91
EGD Gateway provides for integration with EGD protocolcompatible controllers.
Supported protocols include:l

EGD (version 2.01)lEthernet UDP/IP

The Ethernet standard supported by the 3500/91 I/O modules
is IEEE802.3 for 10BASE-T and 100BASE-TX (twisted pair).
