Introduction
Overview
The Advance Network Gateway unit with the DataNET (ANG_DN) option
connects equipment residing on an Advance Data Hiway to the Advance
Communication System (ACS) via a DataNET link. The unit functions as a
translator for converting signals and communication protocols. This conver-
sion allows Advance Maxum GC’s and Advance GC’s to communicate with
each other in addition to using each other’s Distributed Control System
(DCS) I/O links.
The DataNET link can use either copper and/or fiber optic cables. In an ex-
isting Data Hiway installation the Data Hiway cable can be used.
DataNET is a Siemens Applied Automation communications protocol that
can be used in place of Ethernet for connecting all installed Maxum and Ad-
vance GC’s. As compared to Ethernet, DataNET provides a higher speed
network and minimizes installation of new field wiring.
The Advance Network DataNET Gateway is fully redundant with two Ad-
vance Network Communications Boards (ANCB) and power supplies. Each
ANCB provides either a channel A or channel B network interface for one
Data Hiway channel and one DataNET channel.
An internal Ethernet cross-link connection via the Ethernet 10Base2 (BNC)
port provides the communication link between the two advance network
communications boards (ANCB).
