Description
If Rising Edge (IN turns from FALSE to TRUE), start the function block with the
precondition that the last operation has been completed.
The channel and length to be operated.
See AWAAWT data type on page 130.
The source string: char array.
Outputs of this instruction are updated asynchronously from the program scan. Output
Q cannot be used to re-trigger the instruction since IN is edge triggered.
FALSE - The function block is not done.
TRUE - The function block is done.
Indicates the number of characters transmitted. Updates when the transmission is
complete and Q is TRUE. NumChar may be less than the Length requested to be
transmitted if the length of the Source String is shorter than the requested Length.
FALSE - No error.
TRUE - An error is detected.
See ABL error codes on page 127.
