three COMs to use in the same program

4 posts in this topic

ciao,

I must use 3 different COMs and send to them some codes

COM number1 is COM1

COM number2 is COM2

COM number3 is COM7

My program listen for a TCP packet and then send something to one of the 3 COMs (client-server solution)

This is a part of the program:

#include "CommMG.au3"

Global $Com_Port = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "Com_Port", "Not_Found")
Global $BitPerSecond = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "BitPerSecond", "Not_Found")
Global $BitDati = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "BitDati", "Not_Found")
Global $Parity = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "Parity", "Not_Found")
Global $BitStop = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "BitStop", "Not_Found")
Global $FlowControl = IniRead(@ScriptDir & "\settings_server.ini", "Serial1", "FlowControl", "Not_Found")
_CommSetPort($Com_Port, $sErr , $BitPerSecond, $BitDati, $Parity, $BitStop, $FlowControl)

Global $Com_Port2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "Com_Port", "Not_Found")
Global $BitPerSecond2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "BitPerSecond", "Not_Found")
Global $BitDati2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "BitDati", "Not_Found")
Global $Parity2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "Parity", "Not_Found")
Global $BitStop2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "BitStop", "Not_Found")
Global $FlowControl2 = IniRead(@ScriptDir & "\settings_server.ini", "Serial2", "FlowControl", "Not_Found")
_CommSetPort($Com_Port2, $sErr2 , $BitPerSecond2, $BitDati2, $Parity2, $BitStop2, $FlowControl2)

Global $Com_Port3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "Com_Port", "Not_Found")
Global $BitPerSecond3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "BitPerSecond", "Not_Found")
Global $BitDati3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "BitDati", "Not_Found")
Global $Parity3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "Parity", "Not_Found")
Global $BitStop3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "BitStop", "Not_Found")
Global $FlowControl3 = IniRead(@ScriptDir & "\settings_server.ini", "Serial3", "FlowControl", "Not_Found")
_CommSetPort($Com_Port3, $sErr3 , $BitPerSecond3, $BitDati3, $Parity3, $BitStop3, $FlowControl3)

and this is anothe part of the receve part of the program

_CommSwitch(1)         ;<------------ COM1
    If StringInStr($Rcv,"01 00 01 00 00 00 00 01 00 07 AA 02 00 01 01 01 01 03 FF 53 0D") Then
        _CommSendString("SBI01O01" & @CR, 1)    
        sleep(100)
        $Data1 = _CommGetString()
        If $Data1 = "SBUD01O1" Then
            $Data1 = "01 00 01 00 00 00 00 01 00 07 AA 02 00 01 01 01 01 03 FF 53 0D"
    EndIf
    If StringInStr($Rcv,"01 00 01 00 00 00 00 01 00 07 AA 02 00 02 02 07 07 03 FF 53 0D") Then
        _CommSendString("SBI02O07" & @CR, 1)
        sleep(100)
        $Data1 = _CommGetString()
        If $Data1 = "SBUD02O7" Then
            $Data1 = "01 00 01 00 00 00 00 01 00 07 AA 02 00 02 02 07 07 03 FF 53 0D"
        EndIf
    EndIf
    _CommSwitch(2)     ;<------------ COM2
    If StringInStr($Rcv,"Accendi Teleruttore") Then
            _CommSendString(83)   
        sleep(100)
    EndIf
    If StringInStr($Rcv,"sPEGNI Teleruttore") Then
            _CommSendString(81)   
        sleep(100)
    EndIf

       _CommSwitch(3)      ;<------------ COM7
    If StringInStr($Rcv,"Preview canale 1") Then
        _CommSendString(500)    
        sleep(100)
    EndIf
    If StringInStr($Rcv,"Preview canale 2") Then
        _CommSendString(500)   
        sleep(100)
    EndIf

But this code doesn't work. There is a another way to send a packet to a particular COM port?

Thanks

No, it won't work because you haven't set the ports up correctly.

You have misunderstood how to use the channels. By coincidence I have explained this aspect recently in the commg thread so have a look at


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

Thankyou very much!!

It works now :-)
