Password Management - FDM121 User Guide

General Description

Four passwords are defined, each one corresponding to a level.

A level is assigned to a role:

Levels 1, 2, and 3 are used for general-purpose roles, like an operator role.
Level 4 is the administrator level. The administrator level is required to write the settings to the ULP modules using the EcoStruxure Power Commission software.

When an FDM121 command is protected by password, the user must enter the password of the right level in a dedicated window.

Initial Passwords

The password values set in factory are:

Password level	User profile	Factory setting

Level 2	Engineer	‘2222’ = 0x32323232
Level 3	Operator	‘3333’ = 0x33333333
Level 4	Administrator	‘0000’ = 0x30303030

Resetting passwords with the EcoStruxure Power Commission software is only available with the Schneider service user profile.
