a robot always show the error log :

warning: 40501
TIMEOUT
TASK:MAIN
A time out interrupt the execution of Readbin ...

Reacovery: ERR_DEV_MAXTIME

below is the code

  FUNC num ReadByte()
    VAR num Input;

    ! Read character from serial channel
    Input:=ReadBin(DriveGripperTime:=0.1);
    RETURN Input;
  ERROR
    RETURN -1;
  ENDFUNC


and the proc which calls the func
.....
    WHILE ReadByte()<>-1 DO
    ENDWHILE
.....


what's the the problem ? caused by software or  by hardware? or some system setting?

the robot is IRB6600 M2000 , and I/O CPU Board had been replaced.

please give me some useful information ?  thanks!

    What happens if you increase the timeout? 0.1 is pretty short...

    Do your COM port settings match the device you are trying to connect to?

    What happens if you don't read it from a loop, i.e. can you read it once? Do you have any WaitTime in your WHILE loop? You should have at least 0.1 in the loop.

    Have you opened the serial port elsewhere in your code?

    Has something changed that made this stop working, or are you trying to debug it for the first time?
