SECURITY
Logon feature
To prevent unauthorized access to a running system, ControlEdge
Builder supports three user types including Operator, Engineer and
Administrator, and this user management controls the operating
privileges. A password is required when operating as a specific user
type connecting to a running controller. The default password of each
user type is listed as follows:
User Name Password
Operator Oper@123
Engineer Engr@123
Administrator Admin@123
It is recommended to changed the passwords periodically. It is also
recommended to share the passwords with only the minimum
required people, who need to perform configuration operations on
ControlEdge 900 controller and ControlEdge 2020 controller.
For more information, see “User Privileges” in the ControlEdge
Builder User’s Guide.
