Users and user groups
The TwinCAT HMI User Management is based on a user group concept. The user groups are managed centrally in the TwinCAT HMI Server (TcHmiSrv). The actual users, who may be members of one or more user groups, are made available as a data source by the server extension TcHmiUsermanagement. The creation and editing of users and user groups takes place within the development environment via the TwinCAT HMI Configuration window under the category Users and Groups, within which the individual Users and Groups are listed.
