I am using Excel 2016 as a means to capture data from a piece of equipment that has a web IP address/USB port. If I use a web browser, the URL would be http://127.0.0.1:44789/evox/bacnet/2/0/51/117 and would get back a response <int< font=""> xmlns:trane="</int<>trane:evox" href="/evox/bacnet/2/0/51/117" val="64"/>
The val represents °F

I use Excel to loop through many different points and verify the point are working. Then we change the units on the equipment from Imperial to SI (metric) and recheck to make sure the equipment response in the correct units.
Excel appears to look at memory and not get the new information. It shows the old value.
If I do it with a web page (chrome or IE) it is correct.
If I close Excel and reopen it and will get the updated information.

My question is how do I get Excel to not use what is cached and get a fresh value

Public Sub Looping()


Dim xmlhttp As New MSXML2.xmlhttp, myurl As String, xmlresponse As New DOMDocument


On Error GoTo ErrorHandler1


For Each cell In Range("D90:D200")
    If Not IsEmpty(cell.Value) And cell.Value = "Pause" Then
        MsgBox ("In Tracer TU, Utilities - Controller - Controller Settings - Protocol, change the units, then click OK")
    ElseIf Not IsEmpty(cell.Value) And cell.Value = "Pause1" Then
        msgboxResult = MsgBox("Did the Unit change?", vbYesNo)
        If msgboxResult = vbNo Then Exit Sub
     
    
    ElseIf Not IsEmpty(cell.Value) Then
        myurl = cell.Value
        xmlhttp.Open "GET", myurl, False
        xmlhttp.send
        xmlresponse.LoadXML (xmlhttp.responseText)
        strRet = xmlhttp.responseText


        StrOut = Right(strRet, Len(strRet) - 40)
        cell.Offset(0, 1).Value = StrOut
    End If
Next


ErrorHandler1:
    StrOut = ""
    Resume Next


End Sub

Select a hidden cell
Somehide hide payroll data in column G? Press F5. Type G1. Enter. Look in formula bar while you arrow down through G.
Sort by date Sort by votes
Get a fresh value from where? The code is looking in col D, but the new value is placed in col E.

I don't follow that. What does "repeats it self" mean?
