Hi all
Is there a way that we can program the pv750 or 450 so that if a shutdown fault has accoured that a password page comes up and before you can restart the machine you first have to enter a password can some one please assist me with this

To create a password protect screen, there is already a post on this forum which would be used to create the enter password screen(Just search for password protect on the forum to find this post). Then all you would have to do is create another variable to show this page when a shutdown message is received. To do this, create a state machine that will change this new variable from a 0 to a 1 when the UserDefinedVariable.Dm1.LampStatus equlas 2 (which means the unit received a shutdown message). Also be sure to set this variable to a saved value, and save this variable on change so that when the unit starts back up the password screen will show. Then change the script GaugeScreenInit Line 127 to an if statement for when your user defined variable is equal to 1 to go to your password screen, else go to current screen. Be sure to change this new variable back to 0 when a correct password has been enabled.

Marcell,

Here is a demo based on the standard configuration that lets you save a log file to a flash drive and requires a password when you restart after a shutdown.

The changes are:

New Variables:

• UserDefinedVariable.Datalogger.Status
  UserDefinedVariable.Password
  UserDefinedVariable.Password1000sDigit
  UserDefinedVariable.Password100sDigit
  UserDefinedVariable.Password10sDigit
  UserDefinedVariable.Password1sDigit
  UserDefinedVariable.PasswordRequired

New Images:

• Flashdrive0
  Flashdrive1
  Flashdrive2
  Flashdrive3
  Start

New Pages:

• Data Logging
  Password

New Script:

• CheckPassword (from post viewtopic.php?f=7&t=138)

New State Machines:

• Data Logging Stop
  Data Logging Clear
  Data Logging Output
  Data Logging Start
  GoToDataLogging
  GotoPasswordScreen
  Password
  PasswordRequired

Modified Page:

• Default Utilities Menu View
  • Added button to go to Data Logging

Modified Script:

• GaugeScreenInit
  • Added variable:

    Code: Select all

    double PasswordRequired;

    Added code at the end:

    Code: Select all

    	smRead(smGetHandle("UserDefinedVariable.PasswordRequired"), PasswordRequired);	
    	if( PasswordRequired == 0 )
    	{
    		GaugeScreenGoToCurrent();
    	}
    	else
    	{
    		sendEvent(EventID("Transition to show password screen"));
    	}
