# 8.8 User Permission

**Introduction**

User permission is one of expansion function in PI Series HMI; it provides multi-level of permission for control HMI operations. User need to set the user and group during designing project. Different groups have different permission levels for accessing. Each user should be added into the specified group; it is possible to add the same user into different groups.

Operating record: it records user operations information, the records files are saved in HMI flash; its path is \[\\\flash\\\UserOperationLogs.db].

When it is on simulator mode, the files are saved in C disk, its path is \[C:\\\WECON\UserMgrFile\UserOperationLogs.db].

**Operating procedure of settings**
