EthernetIPforMicro800Com1 to read an array of PLC Addresses

[FuzyDragon]

I'm currently working on a way to read multiple PLC Addresses in a single call as opposed to individually stating each Address (because I have a lot of addresses to read). The code I have so far looks like this: Inside a ButtonClick trigger I have the driver read the addresses and create the array

 For x As Integer = 1 To 120
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].in1", 120)
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].in2", 120)
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].in3", 120)
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].out1", 120)
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].out2", 120)
            EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[" & x.ToString & "].out3", 120)
 Next

Then when data is received I use this piece of code

 Private Sub EthernetIPforMicro800Com1_DataReceived(sender As Object, e As Drivers.Common.PlcComEventArgs) Handles EthernetIPforMicro800Com1.DataReceived

        For x As Integer = 1 To 120
            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].in1 " Then
                For index As Integer = 0 To 119
                    CalDataToLog(index) = e.Values(index)
                Next
            End If

            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].in2" Then
                For index As Integer = 131 To 250
                    CalDataToLog(index) = e.Values(index)
                Next
            End If

            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].in3" Then
                For index As Integer = 262 To 381
                    CalDataToLog(index) = e.Values(index)
                Next
            End If

            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].out1" Then
                For index As Integer = 393 To 512
                    CalDataToLog(index) = e.Values(index)
                Next
            End If

            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].out2" Then
                For index As Integer = 524 To 643
                    CalDataToLog(index) = e.Values(index)
                Next
            End If

            If e.PlcAddress = "DAQThermocouple[" & x.ToString & "].out3" Then
                For index As Integer = 655 To 774
                    CalDataToLog(index) = e.Values(index)
                Next
            End If
        Next
End Sub

None of this actually catches the data though. I think it may be a problem with reading the PLC Addresses initially but I'm not sure.

Thanks in advance for any advice or help

Your read loop is going to try to preform 86,400 reads. If you break out your for-Next loop, this is what it would look like:

EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[1].in1", 120)  '* Read elements 1-121
EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[2].in1", 120)  '* Read elements 2-122
EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[3].in1", 120)  '* Read elements 3-123
EthernetIPforMicro800Com1.BeginRead("DAQThermocouple[4].in1", 120)  '* Read elements 4-124
.
.
.

My guess is that is not your intention

OK I see my issue with the read portion. Thank you for the quick response.
