Motoplus application alarm

Hi everyone,
I use motoplus to make a application for ethernet communication. And then, I create 3 tasks in void mpUsrRoot() as follow.

Task_id1 = mpCreateTask(MP_PRI_TIME_NORMAL, MP_STACK_SIZE, (FUNCPTR)mpMain,
arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10); //main frame of the application and where I create a client
Task_id2 = mpCreateTask(MP_PRI_TIME_NORMAL, MP_STACK_SIZE, (FUNCPTR)mpOnRecvData,
arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10); //for receiving data from my computer
Task_id3 = mpCreateTask(MP_PRI_TIME_NORMAL, MP_STACK_SIZE, (FUNCPTR)mpSendData,
arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10); //for sending data to my commputer every 50ms
In the mpRecvData, operation like following:

void mpOnRecvData()
{
while(1)
{
RecvCount = mpRecv(SockHandle,RecvBuf,100,0);
}
}

Now I compile the code and load the *.out to my robot. But the robot can not startup with many errors.
And then, I comment some code like following.
void mpOnRecvData()
{
//while(1)
//{
// RecvCount = mpRecv(SockHandle,RecvBuf,100,0);
//}
}
But the result is always that the robot can not startup normally. So I comment the code which is to create the task like following.
//Task_id3 = mpCreateTask(MP_PRI_TIME_NORMAL, MP_STACK_SIZE, (FUNCPTR)mpRecvData,
arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10); //for sending data to my commputer every 50ms
Then the application can run very well and can send data to my computer.

I need help with this issue.
Thank you very much!

BR!

Wat errors (number) do you get ?

Alarm 1020 - 1 means that there is more than one executable file present on your controller (.OUT file).
Delete all .OUT files in motoplus menu in maintenance mode except the one you want to execte.

Thank you. I can find this error number and its description in the manual of motoplus. But I can not find others.

Error 1050-1 means that communication between HMI (teachpendant) and Dx controller is broken.

In your source code I see your receive function is mpOnRecvData()

In mpCreateTask you pass the funtionpointer (FUNCPTR)mpRecvData ??

When mpRecvData is decleared somewhere as "external", the compiler does not give an error or even a warning ... But your code will not run.

Good! Thank you!

while(1){...} is always very bad, you need something like while(1){...;mpTaskDelay(1);} -> that's much better otherwise you need way to much process time.
Please try it, you will see the difference immediately.

Yes, you are right. I find that if I add a mpTaskDelay in my while(1){}, the application will work well!

Thank you!
