My last suggestion to you is to be patient and wait for Archie to implement Modbus string reading into the driver.
Godra, Again Thanks for your help and quick reply's. This is one of the best Forum's and product for any type of automation. I will post when I get it solved.
Thanks to all.
Godra,
P2-550 PLC from AutomationDirect, Scanner string in 4 register’s using an “AnalogValueDisplay” to show the string on the form. Using The ModbusTCPCom, and a timer for the read event. Starting the time on form load. Timer set to 200ms.
This is working great.
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
Dim str(7) As String
'* Read it from the PLC
str = Modbus51.Read("40002", str.Length)
Dim ResultString As String
ResultString = MfgControl.AdvancedHMI.Drivers.Common.CalculationsAndConversions.WordsToString(str)
AnalogValueDisplay34.Text = ResultString
End Sub
This will work fine on the AutomationDirect Productivity2000 series controlers. Thanks again for all the time and effort you put into helping with this. This is the best product around and the support is Great... Larry
