lication 1010-1, Safety Requirements for Electronic Measuring Appara-
tus, and has been supplied in a safe condition. This manual contains in-
formation and warnings, which have to be followed by the user to ensure
safe operation and to retain the product in a safe condition.
WARNING statements identify conditions or practices that could result in
personal injury or loss of life.
CAUTION statements identify conditions or practices that could result in
damage to the equipment or other property.
DANGER indicates a personal injury hazard immediately accessible as
one reads the markings.
CAUTION indicates a personal injury hazard not immediately accessible
as one reads the markings, or a hazard to property, including the equip-
ment itself.
This symbol indicates where applicable cautionary or other
information is to be found.
DANGER - High voltage
Protective ground (earth) terminal

Safety Practices and Precautions, Continued
Before switching on the power, check that the operating voltage listed on
the equipment nameplate agrees with the available line voltage.
Any interruption of the grounding conductor inside or outside the equip-
ment or loose connection of the grounding conductor can result in a dan-
gerous unit. Intentional interruption of the grounding conductor is not
permitted.
If it is determined that the equipment cannot be operated safely, it should
be taken out of operation and secured against unintentional usage.
To avoid fire hazard, use only a fuse of the correct type, voltage rating
and current rating as specified in the parts list for your product. Use of
repaired fuses or short-circuiting of the fuse switch is not permitted.
DO NOT open the equipment to perform any adjustments, measure-
ments, maintenance, parts replacement or repairs until all power sup-
plies have been disconnected.
Only a properly trained technician should work on any equipment with
power still applied.
When opening covers or removing parts, exercise extreme care since
"live parts or connections can be exposed".
Capacitors in the equipment can retain their charge even after the unit
has been disconnected from all power supplies.

Introduction
Overview
The Advance DataNET Hub (DNH) functions as a communication router
on an Advance Communication System (ACS) network. The DNH is a
fully redundant unit with dual electronics and with dual power supplies.
The electronics are certified for use in NEC Division 2 and IEC (Cenelec)
Zone 2 hazardous locations.
The dual hub modules (designated DataNET ‘A’ Hub or DataNET ‘B’
Hub) are connected via a serial cross-link cable The wiring of the serial
crosslink cable determines which is the ‘A’ Hub.
HUB‘B’
HUB ‘A’
The DNH brings flexibility to the ACS with its eight DataNET downlink
ports, one Ethernet 10BaseT port for interconnecting of DataNET or
Ethernet segments and one uplink port. With its uplink port, the DNH can
be used to connect DNHs together to expand the ACS network, or the
DNH can be used as an interface to an Advance Network Gateway unit.
The DataNET ports can accept copper and/or fiber optic cables. In Data
Hiway installations the DNH can use the existing Data Hiway cables.

Overview, Continued
The Advance DataNET Hub (DNH) is available in three package configu-
rations:
• 19-inch Rack Unit (Figure 1-5)
• Wall Mount Unit (Figure 1-6)
• Zone 1 Wall Mount Unit (Figure 1-7)
The Advance Communication System (ACS) is a high-speed communi-
cations system that uses TCP/IP protocols and addressing to intercon-
nect chromatographs and other process analyzers in a common network.
Figure 1-1 shows the DNH, Advance Network Access Unit (NAU) and
Advance Network Gateway (ANG) connected to the ACS. The NAU con-
nects to the ACS and provides a method to access information coming
from Advance process analyzers including Advance Maxum and
Advance Optichrom GC’s. The ANG is used to connect Siemens Applied
Automation’s equipment residing on an Advance Data Hiway to the ACS.

Overview, Continued
A network of DataNET hubs forms a tree-like hierarchy. A DNH may
connect to as many as eight “down-stream” devices (Maxum Analyzers
or Advance Hub Uplink port). Each down-stream DNH, in turn, connects
to another eight, and so on. No architectural limit is placed on the depth
of the DataNET hub hierarchy. In practice, propagation time considera-
tions and hub loading should allow hierarchies at least six or seven lay-
ers deep without incurring excessive timing delays.

Figure 1-3 illustrates two separate trees of DataNET hubs that share an
Ethernet segment.
A hub can also connect to-and-from an Ethernet device or an Ethernet
compatible Advance Network Gateway (ANG) unit or to and from a non-
redundant Ethernet connection. A tree of DataNET hubs can function as
an Ethernet bridge, transparently connecting all the Ethernet segments
that are attached at any point on the hierarchy. The DataNET hub soft-
ware does not implement any software protocols (e.g. IEEE 802.1 span-
ning tree) to prevent routing loops. Thus, each tree of DataNET hubs
may connect to any Ethernet segment at exactly one point. Multiple Da-
taNET trees may share Ethernet links.

DataNET Hub Operation
Figure 1-4 shows the individual links that connect three DataNET hubs
and several end devices.
The inter-hub links travel across twisted-pair copper or fiber-optic cables.
The link data rate is 2.048Mbps for both cables. The DataNET hub soft-
ware auto-detects the type of medium used on each DataNET port, and
configures the hub accordingly.
Each connection between a DataNET Hub (DNH) and another device
consists of two links. One link connects to the DNH ‘A’ Hub, and one link
connects to DNH ‘B’ Hub. Both links can carry network traffic in normal
operation. In the event that one link becomes unusable for any reason,
the DNH will transparently and automatically re-route traffic on the re-
maining redundant link.

An Advance Network Gateway or Maxum Analyzer that has an Advance
Network Communication Board/DataNET (ANCB/DN) can connect to a
DataNET hub via any of the eight down-stream ports. The ANCB/DN
within these devices functions identically to a DNH.

DataNET Hub Operation, Continued
DataNET switching operates by dynamically and automatically learning
the topology of the network (i.e., which MAC/IP addresses are reachable
through which paths) as Ethernet frames are forwarded through the net-
work. The DataNET hubs require no static initialization of network data in
order to perform their switching function.
Each DNH can learn as many as 1200 IP addresses. This allows the hub
to accommodate up to 1000 instruments (analyzers, etc.), and still be
able to switch frames from another 200 devices (workstations, etc.).
DataNET switching accommodates any Ethernet-encapsulated protocol.
The hub will also “snoop” IP datagrams (RFC 894) and ARP messages
(RFC 826) to learn the locations of all devices using IP.
• MAC Address (Media Access Control). The “built-in” hardware ad-
dress of a device connected to a shared media.
• IP Address is a 32-bit address defined by the Internet Protocol. It is
usually represented in dotted decimal notation. Present address is
127.236.032.239
DataNET hubs operate as layer 2 Ethernet bridges. That is, hubs will
forward frames among connected Ethernet segments and DataNET de-
vices regardless of the upper layer protocols carried in those frames.
In the absence of hardware failures or network overload, the hub soft-
ware will deliver each Ethernet frame to its intended destination (all sta-
tions in the case of Ethernet broadcasts) in order and without duplication.
In normal operation, the network may deliver frames to additional desti-
nations (i.e., to stations whose MAC addresses do not match the frames’
destination address). End devices must be prepared to receive and ig-
nore frames whose destination addresses do not match their own MAC
addresses.
