Title: 3 position sw.
Post by: Darrell on May 01, 2015, 01:00:23 PM

When I start my HMI , the switch always shows Center position , if the bit for right or left is true it still shows the Center position ,   Micrologix 1400 ,  I have to click it to show the correct position

Do you have anything in the properties PLCAddressValueLeft and PLCAddressValueRight? If there is nothing in those properties, it will not sync up with the PLC.

Open SelectorSwitch3Pos.vb and add this code to the PLC Related Properties region:

    Private m_ValueLeft As Boolean
    Public Property ValueLeft As Boolean
        Get
            Return (Value = 0)
        End Get
        Set(value As Boolean)
            If m_ValueLeft <> value Then
                If value Then
                    Me.Value = 0
                ElseIf Not m_ValueRight Then
                    Me.Value = 1
                End If
                m_ValueLeft = value
            End If
        End Set
    End Property

    Private m_ValueRight As Boolean
    Public Property ValueRight As Boolean
        Get
            Return (Value = 2)
        End Get
        Set(value As Boolean)
            If m_ValueRight <> value Then
                If value Then
                    Me.Value = 2
                ElseIf Not m_ValueLeft Then
                    Me.Value = 1
                End If
                m_ValueRight = value
            End If
        End Set
    End Property

What I noticed today was when I load my HMI the switch will sync , but if I happen to click the switch to another position it will not re-sync

I'm using this one as an indicator , to tell me which one is on , Hand/Off/Auto switch for example
