Congratulations on your purchase of the ICC ETH-1000 Multiprotocol EthernetCommunications Gateway. This gateway allows information to be transferredseamlessly between various industrial Ethernet networks and one of several RS-485-based networks. In addition to the supported fieldbus protocols, the gateway

hosts a USB interface for configuring the gateway via a PC.

Before using the gateway, please familiarize yourself with the product and besure to thoroughly read the instructions and precautions contained in thismanual. In addition, please make sure that this instruction manual is delivered tothe end user of the gateway, and keep this instruction manual in a safe place forfuture reference or unit inspection.

For the latest information, support software and firmware releases, please visit Before continuing, please take a moment to ensure that you have received all materials shipped with your kit. These items are:

ETH-1000 Gateway in plastic housingDocumentation CD-ROM

Four black rubber feet

DIN rail adapter with two pre-mounted screws

USB cable

Note that different gateway firmware versions may provide varying levels of

support for the various protocols. For optimal performance, always ensure thatyou are using the latest version of the ICC Configuration Studio and included

firmware.

This manual will primarily be concerned with the gateway's hardware

specifications, installation, wiring, configuration and operational characteristics.

To maximize the abilities of your new gateway, a working familiarity with this

manual will be required. This manual has been prepared for the gatewayinstaller, user, and maintenance personnel. With this in mind, use this manual to

develop a system familiarity before attempting to install or operate the gateway.

3. Gateway Concepts

The ETH-1000 is a member of the Millennium Series communication gateways.Members of this family are designed to provide a uniform interface, configurationand application experience. This commonality reduces the user's learning curve,reducing commissioning time while simplifying support. All Millennium Seriesgateways are configured using the ICC Configuration Studio. The ETH-1000

networks.

The heart of the Millennium Series concept is its internal database. The databaseis a 4 KB, byte-wise addressable data array. This provides a total size of 4096bytes for the entire database, referred to as DBsize in the protocol driver manuals.The database allows data to be routed from any supported network to any othersupported network. Data may be stored into the database in either big-endianstyle (meaning that if a 16-bit or 32-bit value is stored in the database, the mostsignificant byte will start at the lowest address) or little-endian style (meaning thatf a 16-bit or 32-bit value is stored in the database, the least significant byte willstart at the lowest address).

The other fundamental aspect of the Millennium Series is the concept of aconfigurable "service object". A service object is used for any master/clientprotocol to describe what service (read or write) is to be requested on thenetwork. The gateway will cycle through the defined service objects in a round-robin fashion; however, the gateway does implement a "write first" approach.This means that the gateway will perform any outstanding write services before

resuming its round-robin, read request cycle.

are maintained locally within the gateway itself. This greatly reduces the request-to-response latency times on the various networks, as requests (read or write)can be entirely serviced locally, thereby eliminating the time required to execute

a secondary transaction on a different network.

In order to facilitate the free scaling and conversion of native data values, a user-configurable "multiplier" and "data type" exist for some network configurations. Allnetwork values are scaled by a multiplier prior to being stored into the databaseor after being retrieved from the database. The data type is used to determineinterpreted as an integer or a floating point number upon retrieval from the

database.

A typical use of the multiplier feature is to preserve the fractional components ofa network value for insertion into the database. For example, if the floating-pointse e pier ae  tei see aor e ignenics bni aethe network representation (3.19) will be divided by the multiplier value (0.01) to

 Power Supply Electrical Interface

When the gateway is not plugged into a PC via the USB cable, it must bepowered by an external power source or via Power over Ethernet (PoE: refer tosection 5.2). When using an external power source connected to the gateway'spower and ground terminals, ensure that the power supply adheres to thefollowing specifications:

Voltage rating.7 - 24VDCMinimum Current rating150mA (@24VDC)

ICC offers an optional 120VAC/12VDC power supply (ICC part number10755) that can be used to power the gateway from a standard wall outlet.

The power supply must be connected to the gateway's terminal block atterminals TB:5 (POWER) and TB:6 (GND) as highlighted in Figure 1.
