Assigning modules to areas is an important part of defining distinct security areas in the system. Use DeltaV Explorer to create and name plant areas and DeltaV Explorer or Control Studio to assign modules to plant areas.
Use the following steps to develop a security scheme:
- Plan the security requirements for specific parameter types and parameter fields. It is important to choose the number of distinct levels of access control (locks) you will use in your system.
- Name the locks in your security scheme and describe how the locks are to be used.
- Create one or more groups to accommodate users with similar security requirements. Groups are not a required part of the scheme, but they can make security easier to manage when you have multiple users.
- Create an account for each DeltaV system user.
- Assign your users to the groups. A user can be assigned to more than one group.
- Grant keys to the groups to enable the groups to access and change parameters and parameter fields. You can also grant keys to individual users to enable control not granted to the other members of the groups.
