Today, positive motion technology will share with you the download and operation of ". bas" file of ECI3808 motion control card.

1, ECI3808 hardware introduction

1. Function introduction

ECI3808 series control card supports up to 12 axis linear interpolation, arbitrary arc interpolation, spatial arc interpolation, spiral interpolation, electronic cam, electronic gear, synchronous follow, virtual shaft, mechanical finger command, etc; The optimized network communication protocol can realize real-time motion control.

ECI3808 series motion control card supports Ethernet and RS232 communication interface to connect with the computer, receive the instructions of the computer, and connect each expansion module through CAN bus to expand the input and output points or motion axis.

The application program of ECI3808 series motion control card can be developed by using VC, VB, VS, C + +, c# and other software. The dynamic library zmotion.dll is required when the program runs. During debugging, ZDevelop software can be connected to the controller at the same time, so as to facilitate debugging and observation.

(3) the interface function ZAux_ of the calling link controller in the event handling function of the link button. Openeth() links with the controller. After the link is successful, start timer 1 to monitor the controller status.

//Ethernet connection controller

void CTest_BusInitDlg::OnOpenEth()        

{

    char   buffer[256]; 

    int32 iresult;

    if(NULL != g_handle)

    {

        ZAux_Close(g_handle);

        g_handle = NULL;

    }

    //Get IP address

    GetDlgItemText(IDC_IPLIST,buffer,255);

    buffer[255] = '\0';

    //Connect controller

    iresult = ZAux_OpenEth(buffer, &g_handle);

    if(ERR_SUCCESS != iresult)

    {

       g_handle = NULL;

       MessageBox(_T("link failure"));

       SetWindowText("Not linked");

       return;

    }

    SetWindowText("Linked");

    //Turn on timer 1

    SetTimer( 1, 100, NULL );

}

(4) The axis status of the controller is monitored by timer 1.

void CTest_BusInitDlg::OnTimer(UINT_PTR nIDEvent)  //Timer refresh

{

    int32 ret = 0;

    CString tempstr;  

    if(nIDEvent == 1 && g_handle !=0)

    {

        //Get axis parameters for axis 0

        ZAux_Direct_GetAtype(g_handle, 0, &m_atype);

        ZAux_Direct_GetUnits(g_handle, 0, &m_units);

        ZAux_Direct_GetMspeed(g_handle, 0, &m_speed);

        ZAux_Direct_GetAccel(g_handle, 0, &m_accel);

        ZAux_Direct_GetDpos(g_handle,0,&m_dpos);

        ZAux_Direct_GetIfIdle(g_handle,0,&m_idle);

        //Get axis parameters of axis 1

        ZAux_Direct_GetAtype(g_handle, 1, &m_Atype1);

        ZAux_Direct_GetUnits(g_handle, 1, &m_untis1);

        ZAux_Direct_GetMspeed(g_handle, 1, &m_speed1);

        ZAux_Direct_GetAccel(g_handle, 1, &m_accel1);

        ZAux_Direct_GetDpos(g_handle, 1, &m_dpos1);

        ZAux_Direct_GetIfIdle(g_handle, 1, &m_idle1);

        UpdateData(false);

    }

    CDialog::OnTimer(nIDEvent);

}

(5) Download the bas file to the controller ROM through the event handler function of the file download button. (Note: ". Bas" file can also be downloaded through our ZDevelop software)

//Download BAS file to controller ROM

void CTest_BusInitDlg::OnDownload()          

{

    int32   ret;

    CString m_strOpenFileName;

    CFile  openfile;

    if(NULL == g_handle)

    {

        MessageBox(_T("Controller not connected"));

        return;

    }

    CFileDialog fileopen(true, ".bas", NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,  "Basic Files (*.bas)|*.bas|All Files (*.*)|*.*||", NULL);

    if (fileopen.DoModal() == IDOK)

    {

        //Gets the open file name and path

        m_strOpenFileName = fileopen.GetPathName();

        if (!openfile.Open(fileopen.GetPathName(), openfile.modeRead | openfile.modeNoInherit, NULL))

        {

            this->MessageBox("Open Failed!");

            return;

        }

        GetDlgItem(IDC_FILENAME)->SetWindowText(m_strOpenFileName);

        openfile.Close();

        //Download BAS program to ROM

        ret = ZAux_BasDown(g_handle, m_strOpenFileName, 1);

        if (ret != 0)

        {

            this->MessageBox("DownLoad File Failed!");

            return;

        }

        //The file name is obtained by string segmentation

        char* pchar = (LPSTR)(LPCSTR)m_strOpenFileName;

        CString strTmp = strtok(pchar, "\\"); 

        while(1)

        {

           strTmp=strtok(NULL,"\\");

           if (strTmp==_T(""))

           break;

           strcpy(&FileName, (LPSTR)(LPCSTR)strTmp);

        }

    }

}

(6) The controller is realized through the event processing functions of start, stop, pause and continue buttons.

//Run the ZBasic file in the controller

void CTest_BusInitDlg::OnBnClickedRun()

{

    int ret = 0;

    char Temp[100] = "Run \"";

    //Synthesize the command string of "run" file2.bas ", 0"

    strcat(Temp, &FileName);

    strcat(Temp, "\", 0");

    //Stop task 0

    ZAux_Execute(g_handle, "STOPTASK 0", NULL, 0);

    //Open task 0

    ZAux_Execute(g_handle, Temp, NULL, 0);

}



//Stop the task of the controller running ZBasic

void CTest_BusInitDlg::OnBnClickedStop()

{

    //Stop task 0

    ZAux_Execute(g_handle, "STOPTASK 0", NULL, 0);

    //Stop all axis movements

    ZAux_Execute(g_handle, "RAPIDSTOP(2)", NULL, 0);

}



//suspend

void CTest_BusInitDlg::OnBnClickedpause()

{

    //Pause the BASIC program running inside the controller

    ZAux_Pause(g_handle);

    //Pause spindle movement

    ZAux_Direct_MovePause(g_handle, 0, 0);

}



//Continue running

void CTest_BusInitDlg::OnBnClickedResume()

{

    //Continue to run the BASIC program running inside the controller

    ZAux_Resume(g_handle);

    //Continue spindle movement

    ZAux_Direct_MoveResume(g_handle, 0);

}

3, Commissioning and monitoring

Compile and run the routine, and connect the controller through ZDevelop software to monitor the controller status.

1.ZDevelop software connects the controller and opens the debugging mode to view the file name of ". bas" file in the controller.

2. Capture the waveform of continuous small line segments through the oscilloscope function of ZDevelop software. The following is the comparison between oscilloscope waveform and CAD drawing.

A. The operation of ECI3808 is as follows: (the Rom of ECI3808 is only 4KB, so the downloaded Basic file cannot exceed 4KB)

B. The operation of ZMC308B controller is as follows: (the Rom of ECI3808 is only 4KB, so the downloaded Basic file cannot exceed 4KB. Therefore, the operation of the following tracks needs to be realized with the help of ZMC308B controller)

3.ZDevelop software debugging video.

This time, the simple and easy-to-use motion control card of forward motion technology (VI): Basic file download and continuous trajectory processing, which is shared here.
