User is an Account Management section where engineer could add user and its previlege (access level) into project. This security level checking is applicable on front end only, i.e., when request is submitted via http request from client side scripts. Security level checking is not applicable from within tag window of IntegraXor server, as server side execution gains the highest execution rights.
When a user security level is equal or higher than tag security_write level, he or she has the right to change the value of this tag. Be aware that default configuration put no security control to all access, that is security level of zero (0). Meaning all user can do anything without logging in. To impose security check, engineer must first increase security level for the relevant tag(s).
User login is per login per IP basis. This means same user can login via different IP address concurrently. System only maintain single login session per IP. This means only one user can login from one IP at any time. In order to login as another user, the first user must logout.
