Chapter 5 User Management
User Accounts and
Privilege Classes The MicroLogix 1400 controller supports multiple user accounts, each with a
user name and password. Each user account is configured for one of these access
levels:
·
Administrator (all access except write)
·
Write (read/write access only)
(1)
·
Read (read only)
The access level determines which web pages the user can access. You configure
access limits for individual web pages.
Configure Access Limits for
Web Pages
Each page in the MicroLogix 1400 controller has one of these protection levels:
· Administrator
· Write
(1)
· Read
The protection levels are hierarchical. Administrator users can access Read
protected pages.
These pre-defined pages (those web pages that come with the MicroLogix 1400
controller) in the MicroLogix 1400 controller have these default access levels. You
can change the Data View access group, if needed, with administrator privilege
(1)
For MicroLogix 1400, revision 21.006 or later, Write access is not supported and is listed as Invalid from the
drop-down selection.
