Title: Writing Values to Micrologix from Advanced HMI
Post by: khewes on June 06, 2016, 11:47:28 AM

hello all,
I was wondering if there were anyway to write values to my plc micrologix 1000 from the HMI using the advancedhmi software nad not my ladder logic?
For example, I want to set my timers to a specific time, and this time should be in the form of hrs:mm:ss. I would rather use advanced hmi math than ladder logic math because with an ML1000 my memory is very limited and thus every amount of space possible is very valuable.

okay i see that the digital panel meter is what i want to use.  But i would like to change the keypad's layout and output so that a user can put in hrs:mm:ss, and have it converted to seconds only.  How would I go about adding new buttons? I cannot seem to find where the keypad layout is constructed is it under keypad pop up for data entry?

You would have to write some VB code to do this. For instance:

- Add a TextBox to the form
- Add a Button to the form
- Double the button to get back to the code
- Add this code

Code: [Select]

        Dim s() As String = TextBox1.Text.Split(":")
        Dim TotalSeconds As Integer
        '* Make sure 3 items were entered
        If s.Length = 3 Then
            Dim v As Double
            If Double.TryParse(s(0), v) Then
                TotalSeconds += v * 3600
            End If
            If Double.TryParse(s(1), v) Then
                TotalSeconds += v * 60
            End If
            If Double.TryParse(s(2), v) Then
                TotalSeconds += v
            End If

           EthernetIPforCLXCom1.Write("TagName",cstr(TotalSeconds))
        End If
