Privilege Level

ValVue Software Installation and

Privilege Level

Each user is assigned an account with an associated privilege level associated. You provide

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 (lowest) to 9 (highest). Table 2 defines several privilege levels

that control access to specific functions of the ValVue program.

It is recommended that the administrator be assigned a second login name and password

with lower privilege, such as level 4, for routine use.

Privilege Level Details

Table 2 ValVue Privilege Levels

Security Level Description

Level 0 Allows you to login to ValVue only if the connected positioner is in normal operating

mode. You can send commands that replies with configuration, calibration, and

status information, but you cannot change any information. Level 0 users cannot

go to manual mode.

Level 1 Allows you access to either normal operating mode or manual mode. You can

transfer from one to another mode (i.e. you can take the positioner out of normal

mode and put it in manual mode). However, you cannot change the calibration or

configuration.

Level 3 Allows you to change the configuration or calibration values, but does not allow

you to perform operations that stroke the valve (Find Stops and diagnostics).

Level 4 Allows you 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 optional pro-

cess controller. The process controller is an available option. The simulation mode

of the controller allows you to run the process controller without connecting a pro-

cess variable input to the positioner and is useful for learning how to operate the

process controller. Never assign level 8 to ordinary users!

Level 9 Allows access to all positioner functions. In addition, it is the only level allowed to

level 9. There must be at least one user of privilege level 9.
