Network Topology

The 450U-E is an Ethernet device, and must be configured as part of an Ethernet network. Each 450U-E module

must be configured as one of the following:

• Access point or client (station)

• Bridge or router

Access Point vs. Client

The 450U-E module that is configured as an access point acts as the wireless master. The access point accepts

and authorizes links initiated by the client modules, and controls the wireless communications. Clients (stations) are

slave modules, and become transparent Ethernet links when connected to the access point.

Figure 1 shows a connection between two Ethernet devices using 450U-E Ethernet modems. In this example, one

450U-E is configured as an access point and the other as a client.

The 450U-E modules are housed in a rugged aluminum case suitable for DIN rail mounting. The terminals will

accept wires up to 2.5 mm2 (12 gauge) in size. Before installing a new system, it is preferable to bench test the

complete system. Configuration problems are easier to recognize when the system units are close to one another.

Following installation, the most common problem is poor communications caused by incorrectly installed antennas,

radio interference on the same channel, or an inadequate radio path. If the radio path is a problem (the path is

too long, or obstructed), a higher performance antenna or a higher mounting point for the antenna may rectify the

problem. Alternatively, use an intermediate 450U-E module as a repeater.

Each 450U-E module should be effectively grounded via the “GND” screw on the back of the module to ensure that

the surge protection circuits inside are effective. The 450U-E Installation Guide provides details and an installation

drawing appropriate to most applications.

The 450U-E Industrial 802.11-based Wireless Ethernet module provides wireless connections between Ethernet

devices and/or Ethernet wired networks (LANs). The 450U-E is a fixed frequency wireless transceiver that operates

within the 360 MHz to 512 MHz frequency spectrum in one of eight 20-MHz frequency bands, depending on the

model purchased.

The 450U-E module provides two serial connections and an Ethernet connection. It is possible to use all three data

connections concurrently, allowing the 450U-E to act as a device server where wireless connections can be made

between serial devices and Ethernet devices. The 450U-E also provides functionality between serial Modbus RTU

devices and Ethernet Modbus TCP devices. Appropriate driver applications will be required in the host devices to

handle other protocols. The modem is capable of passing VLAN tagged frames.

The Ethernet connection is a standard RJ-45 connection that will operate at up to 100 Mbps. The module will

transmit the Ethernet messages on the wireless band at rates between 1 and 19.2 Kbps, depending on model,

band, encryption methods, and radio paths.

Protective metal housing built to last in harsh environments

Eaton Tripp Lite series industrial ethernet switches offer a convenient

option for connecting devices in demanding environments such as

factories, warehouses and other industrial settings.

Available in unmanaged, lite managed, and fully managed varieties,

these switches have a ruggedized metal case, ESD protection and a

wide operating temperature range to withstand high and low temperatures.

Built for industrial applications and extreme environments

Extreme heat, extreme cold, vibrations, and dust and grime are common

in industrial applications, which means they require equipment designed

to handle it. Eaton’s vast portfolio of industrial products keep your

environment connected and productive.

Crouse-Hinds series MTL 910x FISCO power supply systems provide an

intrinsically safe field network for Foundation™ fieldbus systems in

hazardous areas. Variants are available for integration into proprietary

fieldbus control systems. The output of the power supply modules

complies with the Fieldbus Intrinsically Safe Concept (FISCO) model,

in accordance with IEC standard 60079-27. 

The key advantages of FISCO over earlier ‘Entity’ model installations

to FF-816 are higher available field current and reduced safety

documentation, while retaining the ability to conduct maintenance

while energized and without “gas clearance”.

The 910x systems build on MTL 912x-IS range of power supplies,

which have become established as the industry standard solution for

FISCO networks. The 910x systems now achieve higher levels of overall

system availability by providing redundancy of the power modules.

Fieldbus standards require buses to be terminated at both ends to prevent

signal reflections. In many applications, one terminator is built into the

power conditioner, which is usually located near the control system.

The second terminator is either integrated into the Megablock or fieldbus

barrier wiring component, or added in the form of a separate DIN-rail

mounted unit.

The Crouse-Hinds series MTL range of fieldbus terminators are ideally suited

to provide the terminator that is normally installed in a junction box in the

field (along with a Megablock for interconnecting devices).

A large “T” is placed on all terminator labels for easy identification of the

Terminator location.

Design features

• Terminators are clearly marked with a large ‘T’ making them easy to identify in the field

• Provides some differential and common-mode (cable shield) over voltage protection

• The ground connection on the filedbus terminators are used to shunt any surge currents

that may get on the cable shield to a local ground in the junction box.

Although the normal practice is to ground the cable shield in the control room, this additional

ground connection will not cause ground loops.

• In the event of an overvoltage on the cable shield, a gas discharge tube fires and shunts

this unwanted current to ground

Crouse-Hinds series MTL F30 Ex ic Adaptor is an accessory to our

F300 range of Megablock wiring hubs. The F30 provides intrinsically

safe Ex ic spur connections for fieldbus networks in Zone 2 hazardous

areas. One F30 is used with each Megablock, to limit the voltage at

the spurs to Ex ic levels. When connected to suitably certified fieldbus

instruments, the spurs may be live-worked in accordance with normal

intrinsic safety procedures. The F30 is completely transparent to all

fieldbus communications.

The F30 is compatible with F304. F308 and F312 Megablock types,

typically providing up to 12 Ex ic spurs per fieldbus segment.

Up to two F30s and their associated Megablocks may be connected

to a single segment, to allow the fieldbus trunk to be extended

between junction boxes in the field.

Ex ic replaces the earlier Ex nL technique for energy-limited fieldbus

networks, and brings the technique into line with formal intrinsic safety

procedures.
