Product Description - Momentum 170ENT11001

Front Panel Components

The following figure shows the front of a Momentum 170ENT11001 Ethernet communication adapter.

General Description

The Ethernet communication adapter, Momentum 170ENT11001, enables the connection of the complete family of Momentum I/O modules to an Ethernet network, at either a 10Base-T or 100Base-T communication rate.

The Momentum 170ENT11001 is attached to a Momentum I/O module. The Momentum 170ENT11001 offers the following functions using Ethernet connections.

configure the module through embedded Web pages
exchange
- input and output data
- configuration information
Exchanges communicate using a defined set of Modbus commands over the TCP/IP protocol.
obtain diagnostic information using
- LEDs appearing on the module
- communication statistics displayed on Web pages
download
- operating parameters using the FDR service
- Exec. and kernel updates

The Momentum 170ENT11001 offers the following functions using registers.

allows up to 3 devices to have write access to the Momentum 170ENT11001 with the option of storing their IP addresses in Flash
select holdup timeouts either
- 0 (zero), which selects an indefinite holdup timeout
- 30 (300 milliseconds) through 6000 (60 seconds) in 10 millisecond intervals
Holdup timeouts may be stored to Flash.

For further information about holdup timeouts, see Configuring the Momentum 170ENT11001 Communication Adapter Parameters or Configuring Parameters through the Configuration Group Registers.
select ownership reservation time
- 30 (300 milliseconds) through 6000 (60 seconds) in 10 millisecond intervals
  
  Ownership reservation time can be saved in Flash.

The Momentum 170ENT11001 is one of many communication adapters that mate to a Momentum I/O base in the Momentum family of products.

Increased Functionality

Using a Momentum 170ENT11001 provides all the functionality of the Momentum 170ENT11000 (replaced with the Momentum 170ENT11002), but the Momentum 170ENT11001 offers three additional features:

FDR

Fast Device Replacement

A feature providing ease of maintenance and a backup repository.
Configuration via standard Web browser software

Configure your system with a Web browser. Changes to the system are made easily from these Web pages.
SNMP

Simple Network Management Protocol

SNMP is a powerful, diagnostic tool that provides access to system statistics, which you use to monitor the health of your system.

You may configure a Momentum 170ENT11001 for your needs. The Momentum 170ENT11001 is backward compatible. You may use the Momentum 170ENT11001 as a replacement for a Momentum 170ENT11000.

Ensure that the controller’s communication timeout is long enough to match the network performance and the response time of the Momentum 170ENT11001.

NOTE: Schneider Electric recommends that you use Ethernet switches for distributed I/O networks because switches give more deterministic responses.

Key Features

The Momentum 170ENT11001 includes all the functionality of the Momentum 170ENT11000 communication adapter. (The Momentum 170ENT11000 was replaced with the Momentum 170ENT11002.) The Momentum 170ENT11001 offers the following expanded services:

communication ports

10/100 Mb Ethernet communication port with auto-negotiate capability will:
- automatically detect the port speed of 10 Mbps or 100 Mbps
- auto-negotiate half-duplex / full-duplex port operation
framing methods

10/100 Mb Ethernet communication will support:
- Ethernet II framing
- IEEE 802.3 framing
- auto-detect framing
In auto-detect framing mode the Momentum 170ENT11001 attempts three (3) BOOTP requests with Ethernet II framing. If no response is received, the adapter will then attempt three (3) BOOTP requests with IEEE 802.3 framing.

If a valid configuration exists, the framing type of that configuration will be used. The framing type of the first BOOTP/DHCP response will be chosen as the framing-type run parameter. If no server responds, the default framing type will be Ethernet II.
enhanced IP address acquisition

A Momentum 170ENT11001 will obtain an IP address from
1. BOOTP / DHCP server
2. manual configuration
3. default IP parameters based on adapter’s MAC address
parameter management (at initialization time and execution time)
enhanced power-up error detection

A Momentum 170ENT11001 will detect and indicate default IP address condition, duplicate IP address condition, and complex I/O base failure.
embedded Web pages used for configuration

A series of Web configuration pages enables you to configure some options in the system.

Configure the Momentum 170ENT11001 in its default (out-of-the-box) condition in the absence of a BOOTP / DHCP server or previous configuration.
embedded Web pages used for diagnostics

A series of Web diagnostic pages enables you to monitor the health of the system.
enhanced LED error reporting
SNMP

full support of Simple Network Management Protocol (SNMP)

support of public MIB-2 and the Schneider Electric Transparent Factory Private MIB for device management on the network.
FDR

The adapter supports Fast Device Replacement—client

As an FDR client the adapter will retrieve its IP and configuration parameters from a DHCP server and FTP server respectively. The presence or absence of a role name will control participation in an FDR environment.

The Momentum 170ENT11001 communication adapter will allow a Momentum I/O base both to reside on an Ethernet network and to communicate using Modbus messages over TCP/IP protocol.
