  Hi All,

  Just create a timer object, dobleclick on the object and edit the method to read the multiplexer and disable the timer afterwards.
  in the object properties the timer must be disabled and the time must be in 5000 milisecs.
  

  
  In the subroutine where the multiplexer is activated, enable the timer with timer.enable=true.

  sorry I face problem again in the timer. I write this code in the
  

  
  public sub Cyl()
  Do Until cyclePower = 2
      'Go to Sub Cycle Power
      Call CyclePowerRoutine
      'MsgBox ("GO To Sub Cycle Power")
      cyclePower = cyclePower + 1
  Loop
  end sub
  

  
  Public Sub CyclePowerRoutine()
     'Open GPR
     MsgBox ("Open")
     frmTenData.Timer1.Interval = 1000
     frmTenData.Timer1.Enabled = True
     intCnt = 1
  End Sub
  

  
  This 2 code are in the module, and i create the time object at form and write the code like: -
  Private Sub Timer1_Timer()
     If intCnt = 2 Then
         'Close GPR
         MsgBox ("Close")
         Timer1.Enabled = False
     Else
         intCnt = intCnt + 1
     End If
  End Sub
  

  
  My timer only activate when the cyclePower = 2 but I want the timer activate when I call the "CyclePowerRoutine" and disable when cyclepower = 2. What mistake I make? Can help in coding? Thanks.

  "My timer only activate when the cyclePower = 2 but I want the timer activate when I call the "CyclePowerRoutine" and disable when cyclepower = 2. What mistake I make?"
  

  
  It's an easy one, you believe that "only activate when the cyclePower = 2" but the reality is that the loop continued from cyclePower =1 to 2, too fast, so you didn't saw the cyclePower=1, the processing is parallel so the other routines run "almost at the same time".
  

  
  

  
  In your case it's better to stop processing with a flag assigned at the right moment (and being the flag a global variable).
  

  
  public sub Cyl()
  Do Until cyclePower = 2
     'Go to Sub Cycle Power
    'Open GPR
     MsgBox ("Open")
     Timer1.Interval = 2000
     Timer1.Enabled = True
  

  
     do
       doevents
     loop until not(Timer1.Enabled)
     cyclePower = cyclePower + 1
  Loop
  end sub
  

  
  Private Sub Timer1_Timer()
        'Close GPR
        MsgBox ("Close")
        Timer1.Enabled = False
  End Sub
  

  
  So the is syncronized (but why you started with 5 seconds and now are 2?).
