GE 3500/91 EGD Specifications

3500/91 EGD Communication Gateway Module

Description

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 protocol compatible controllers (e.g.
GE Mark™ VIe controllers, etc).

Supported protocols include:

• EGD (version 2.01)

• Ethernet UDP/IP

The Ethernet standards supported by the 3500/91 I/O modules are IEEE802.3 for
10BASE-T and 100BASE-TX (twisted pair), and IEEE 802.3u for 100BASE-FX (fiber
optic).
