dear MicroMan, see that Manual, where you can find anything about the RETVAL-Parameter from the SFC´s: http://support.automation.siemens.com/WW/view/en/44240604/0/en page303 especially from the SFC13: • If an error occurs while the function is being executed, the return value contains an error code. • If no error occurs during the data transfer, RET_VAL contains the length of the data read in bytesas a positive number. |
FCK WAR! |
