Password Management

General Description

Remote access to data on MicroLogic control units and the ULP modules of the IMU is protected by password. Remote access includes:

EcoStruxure Power Device app
EcoStruxure Power Commission software
FDM128 display
FDM121 display
The communication network
IFE/EIFE webpages

The following four profiles are defined for remote access. An IMU has a different password for each user profile:

Administrator
Services
Engineer
Operator

The following table shows the functions allowed for each user profile:

Default Passwords

WARNING
POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY Change default passwords at first use to help prevent unauthorized access to device settings, controls, and information. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The default password for each user profile is as follows:

User profile	Default password
Administrator	‘0000’ = 0x30303030
Services	‘1111’ = 0x31313131
Engineer	‘2222’ = 0x32323232
Operator	‘3333’ = 0x33333333

Changing a Password

A password can be changed with EcoStruxure Power Commission software.

Entering the current password for a given user profile is required to change the password of this user profile. Entering the Administrator password enables you to change the password of any user profile.

A password is composed of exactly 4 ASCII characters. It is case-sensitive and the allowed characters are:

Digits from 0 to 9
Letters from a to z
Letters from A to Z

IMU Passwords

The MicroLogic X control unit and the ULP modules of the IMU must be protected by the same passwords.

When using EcoStruxure Power Commission software to change a password, the password is changed in the MicroLogic X control unit and the ULP modules of the IMU.

It is compulsory to assign the current IMU passwords to a new module in the IMU in the following cases:

Addition of a new ULP module in the IMU.
Replacement of the MicroLogic X control unit or of one of the ULP modules in the IMU.

Use EcoStruxure Power Commission software to change the passwords of a new module to the current IMU passwords.

Example:

An IO module is added to an IMU consisting of a MicroLogic X control unit and an IFE interface. The IO module has the default passwords, for example, Administrator = 0000.

The current IMU Administrator password = 4321.

Use EcoStruxure Power Commission software to change the default Administrator password of the IO module (0000) to the IMU Administrator password (4321).

Modify the other default passwords of the IO module in the same way, changing them to the passwords of the current IMU.

Password Reset

In the case that the Administrator password of the IMU is lost or forgotten, the password can be reset to the default password with EcoStruxure Power Commission software and the support of the Schneider Electric Customer Care Center.
