Querying
You will often find, when working in AVEVA E3D™, that you need to check existing information about some aspect of the program’s operations. For example, you may need to find out about any of the following:
•
The current usage of the program in terms of users, modules and databases.
•
The unique code which identifies the process you are running and the station you are running it from (useful for generating unique work file names).
•
The current setting of a command option.
•
The contents of part of a particular database; for example, the current setting of an attribute or the list of member elements owned by a specific element.
•
The elements which match specific selection criteria entered by you.
Each application allows you to ask about some of these topics, the scope of the facility being dependent upon the particular module you are using.
