Figure 1. ValVue System Administration
Privilege Level
Each user is assigned with an account. Each account, has a privilege level associated with it. You pro-
vide ValVue users an appropriate privilege level so you can keep field devices secure from the actions of
unknowledgeable or unauthorized users.
Privilege level ranges from 0 to 9, and level 0 is the lowest and 9 the highest. The following defines
privilege levels, which control access to specific functions of the ValVue program.
•
Level 0:
Allows the user to logon to ValVue only if the connected SVI is in normal operating
mode. The user can send commands that will reply with configuration, calibration, and status
information, but the user can not change any information. Level 0 users cannot go to manual
mode.
•
Level 1:
Allows the user access to either normal operating mode or manual mode. The user
can transfer from one to another mode (i.e. the user can take the SVI out of normal mode and
put it in manual mode). The user cannot, however, change the calibration or configuration.
•
Level 3:
Allows the user to change the configuration or calibration values, but does not allow
the user to perform operations that stroke the valve (Find Stops and diagnostics).
•
Level 4:
Allows the user to perform all operations except “Save Factory” standard valve
signature and “Restore SVI Memory”.
•
Level 8:
This level is intended for training and should be used cautiously. It grants all of the
privileges of level 4 plus allows access to the simulation mode of the process controller. (The
simulation mode of the controller allows the user to run the process controller without
connecting a process variable input to the SVI and is useful for learning how to operate the
process controller).
