12.2Logging On and Access Levels

An E2 may be programmed with up to 25 different

users. A user basically consists of a username, a password, and an access level. Whenever a username and password are entered during login, the E2 searches the user records for the username and password. If found, the E2 will log the user in at the access level configured for the user in the user records.

The access level determines how many of the E2’s fea- tures the user may use. The E2 uses four access levels, one being the lowest, and four being the highest. Table 12-1gives a description of each level and the capabilities they have access to.

Level 1	Read-only access. Users may generally
	only view status screens, setpoints, and
	some system settings.
Level 2	Setpoint and bypass access. Users may
	perform all the tasks a level 1 user may,
	and they may also change control setpoints
	and bypass some devices.
Level 3	Configuration and override access. Users
	may perform all the tasks a level 2 user
	may, and they may also override system
	settings, create new cells, and program
	new applications.
Level 4	System Administrator access. All E2 func-
	tions are accessible by a level 4 user.
