HELLO people,

i wanna do data base of loging. It means that i wanna know in what time who touch to panel,

i creat the new user,new pasword, 

than make button and give to this button that only new user can touch it

How make log data base?

If you want to log the name of the user as a string you need to use "HMI Alarms",
not "Historical Data (but if you just log USER-IDs you can use this, too.)

• Create 2 HMI tags: "User_name" (WString) and "Trigger_User"  (Integer or similar).
• Create an new "Analog alarm" and choose the trigger tag ("Trigger_user").
• Choose a fitting "Alarm class" or better, create your own ("Log_User").
• Create and select a "Log" for your alarm class ("Log_User").
• Select your trigger Tag and set a limit (Const: 0).
• activate "Report"

Edit your button:

• Add to events: "GetUserName" (Tag: "User_name")
• Add to events: "SetTag" (Tag: "Trigger_User", Value: 1)
• or Add to events: "ShowSystemAlarm" (HMI Tag: "User_name")

The time is added automatically.
