Configuration of Signal Write Groups
Check out how to define a Signal Write Group to write Signal values and configure its authorization settings as desired.
The Write Groups view displays the available Write Groups and allows the user to create new ones using the contextual menu. The signals are assigned to the existing write groups and the users with access to the write groups can write the values of the signals contained by them.

The write groups access is defined per user inside i4scada User Manager.
The following write groups properties are displayed in the write groups view:
