Configuring the Momentum 170ENT11001 Communication Adapter Parameters

Overview

This topic describes the embedded Web pages that allow you to change the configuration parameters.

Changing the Current Communication Adapter Parameters

Configure the configuration (runtime) parameters of the Momentum 170ENT11001 on this page.

NOTE: The Schneider Electric default configuration password is httpcfguser (lower case).

The Current Communication Adapter Configuration page permits configuring the following configuration (runtime) parameters by entering values in the appropriate fields:

I/O configuration
- reservation time (default: 6000 (60 seconds))
- holdup time (default: 100 (1 second))
masters IP addresses
- master1 IP
- master2 IP
- master3 IP
Specify up to 3 IP address to which write privileges will be granted.

Summarizing the Communication Adapter Parameters

WARNING

LOSS OF COMMUNICATION — INDEFINITE HOLDUP TIME

If indefinite holdup time is selected and communication is lost between the controller and the Momentum 170ENT11001, the I/O outputs will hold last value written until communication is reestablished.

Configure the controller to periodically read the I/O module health (Word 10) of the system status block, register 4F801 hex, of the Momentum 170ENT11001 to verify that the communication between the controller and the Momentum 170ENT11001 is operational and that the controller is healthy.
The system status block is described in the System Status Block Table in Using the Status Group Registers.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The reservation time, holdup time, and masters IP addresses are accessible through the embedded Web pages or by accessing the registers using Modbus TCP/IP. For a discussion of these registers, see Configuring Parameters through the Configuration Group Registers.

Using the Check Box

Under the masters IP addresses area, one check box appears on this page. This check box pertains to using the FDR service.

Check Box Name	Description
Fall back to stored application parameters in the absence of an FDR server	When booting up, this check box informs the device of the expected behavior when an FDR server is not available. If an FDR server is not available when device is booting up and: check box is selected: Device uses stored parameters. check box is not selected: Device goes to Safe I/O mode.

NOTE: When using a BOOTP server, the device will always use the stored parameter values or default values if the stored values have not been set.

Using the Web Page Command Buttons

Five command buttons carry out the changes made to the parameters.

Button Selected	Result
Display stored	Reread the page and display the stored values, the values in the FLASH.
Display current	Reread the page with current values, the values in the RAM.
Display factory defaults	Reread the page and display the factory defaults.
Apply	Store the parameters displayed on the page into: current values in RAM The Apply button will not change either the contents of FLASH (nonvolatile memory) or the contents of the FDR server. If the change is successful, you will see the Communication Adapter Apply Confirmation page displaying this message, Configuration applied successfully. If the change is not successful, an error message displays. Refer to the system log page for additional information.
Save	Store the parameters displayed on the page into: FDR server (if using FDR) FLASH (nonvolatile memory) current values in RAM The Save button will change the contents of FLASH and the contents of the FDR server. If the change is successful, you will see the Communication Adapter Save Confirmation page displaying this message, Configuration saved successfully. If the change is not successful, an error message displays. Refer to the system log page for additional information.
