Notification before use

Depending on the type of product you are using, the definitions of ‘Parameter’, ‘IO Logic’, ‘AxisStatus’, etc. may be different. This example is based on ‘Ezi-SERVO’, so please apply the appropriate value depending on the product you are using.

Example)

FM_EZISERVO_PARAM           // Parameter enum when using 'Ezi-SERVO'    
FM_EZIMOTIONLINK_PARAM      // Parameter enum when using 'Ezi-MOTIONLINK'

0. Program scenario

[EN]
1. Connect a device. 2. Get product information. 3. Close connection.

[KR]
1. 장치 연결. 2. 제품 종류 확인. 3. 연결 해제.

1. Connect

const wchar_t* sPort = L"ttyUSB0";
unsigned int dwBaudRate = 115200;
int nPortID = 0;

bool Connect(const wchar_t* sPort, unsigned int dwBaudRate, int nPortID)
{
    bool bSuccess = false;

    if (FAS_Connect(sPort, dwBaudRate, nPortID) == false)
    {
        printf("Connection Fail!\n");
        bSuccess = false;
    }
    else
    {
        printf("Connection Success!\n");
        bSuccess = true;
    }

    return bSuccess;
}

[EN]
‘FAS_Connect’ is a function for RS-485 connection through PortNo and BaudRate. If the function returns ‘TRUE’, the connection is successful.

[KR]
’FAS_Connect’는 PortNo와 BaudRate를 통해 RS-485 통신 연결을 하는 함수입니다. 함수가 ’TRUE’를 리턴하면 연결이 성공한 것입니다.

2. Get product info

bool CheckDriveInfo(const wchar_t* sPort, int nPortID, unsigned char iSlaveNo)
{
    unsigned char byType = 0;
    char IpBuff[256] = "";
    int nBuffSize = 256;
    int nRtn;

    // Read Drive's information
    nRtn = FAS_GetSlaveInfo(nPortID, iSlaveNo, &byType, IpBuff, nBuffSize);
    if (nRtn != FMM_OK)
    {
        printf("Function(FAS_GetSlaveInfo) was failed.\n");
        return false;
    }

    printf("Port %S / Slave No %d : TYPE= %d, Version= %s\n", sPort, iSlaveNo, byType, IpBuff);

    return true;
}

[EN]
After successful connection, a function ‘FAS_GetSlaveInfo’ was used to check product information. This function is not required for connection, but to just show an example of using a function after successful connection.

[KR]
연결 성공 후 제품의 정보를 확인하는 함수(FAS_GetSlaveInfo)를 사용하였습니다. 이 함수는 연결에 필요한 함수가 아닙니다. 연결 후 임의의 함수를 호출한 것입니다.

3. Connection close

// Connection Close
FAS_Close(nPortID);

[EN]
Use ‘FAS_Close’ to close the connection.

[KR]
’FAS_Close()’를 통해 연결을 해제할 수 있습니다.
