Connecting Unity Loader to the Processor

To establish a connection between Unity Loader and the processor, follow these steps:

Step

Action

Open Unity Loader on your PC: Start > Programs > Schneider Electric > Unity Loader. Unity Loader opens and displays the Project tab:

2

In the Connection part of the page, make the following settings:

Media

Select either:

  • Ethernet (for a 171 CBU 98090 or 171 CBU 98091 processor)

  • USB (for a 171 CBU 78090, 171 CBU 98090 or 171 CBU 98091 processor)

Address

Select or type in the address of the processor, for example:

  • SYS (for USB)

  • the processor IP address (for Ethernet)

3

Click Connect.

Performing the Upgrade

Before beginning a firmware upgrade, confirm that the processor is in Stop mode.

The firmware upgrade for a processor is contained in a file with an .LDX extension. The single .LDX file contains the necessary processor firmware upgrades.

Each of the 3 versions of the processors requires the use of a unique .LDX file. Before upgrading the firmware, Unity Loader confirms that the firmware upgrade file is compatible with your processor.

Do not interrupt the firmware download process:

  • Do not allow an interruption to the power or the communications during the firmware upgrade process.

  • Do not shut down the Unity Loader software during the upgrade.

If the firmware download process is interrupted, the new firmware is not installed and the adapter continues to use the old firmware. If an interruption occurs, restart the process.

Open Unity Loader on your PC and update the firmware for the remote I/O adapter:

Step

Action

1

After Unity Loader has connected to the module, click the Firmware tab:

2

In the PC area, click the ellipsis ( ...) button to open a dialog where you can navigate to and select the firmware file for your Momentum processor. The firmware is contained in a Unity Loader file (.ldx extension).

After you select the firmware file and close the dialog, the selected revision of this firmware is displayed in the list on the left, and the current version of the firmware is displayed in the list on the right.

3

When the arrow in the middle of the screen (above) is green, click Transfer .

NOTE: Only click Transfer if the arrow is green. A yellow arrow indicates that the firmware file on your computer is the same version or newer than the file selected for transfer; a red arrow indicates that the firmware on the computer is not compatible with the Momentum processor.

4

Click yes on the 2 dialogs that appear. A third dialog appears (below), which indicates the transfer status with the blue bars at the bottom of the screen. After the transfer is complete, click Close.

5

In the Unity Loader software, click Disconnect and close the window.

6

Reboot the processor to finalize the firmware update.

Unity Loader includes its own user documentation. Refer to Unity Loader, User Guide for assistance when you perform the firmware upgrade.
