官方故障排除步骤
Parameters: %1 = Channel number %2 = Block number, label %3 = Source string Definitions: During initialization, a value has been assigned to a variable that does not correspond to the type of the variable, nor can it be converted to the data type of the variable. Overview of type conversions: - from REAL to REAL: no, INT: yes1), BOOL: yes, CHAR: yes2), STRING: - from INT to REAL: yes, INT: no, BOOL: yes, CHAR: yes2), STRING: - from BOOL to REAL: yes, INT: yes, BOOL: no, CHAR: yes, STRING: - from CHAR to REAL: yes, INT: yes, BOOL: yes, CHAR: no, STRING: yes - from STRING to REAL: -, INT: -, BOOL: yes, CHAR: yes3), STRING: no 1) Value <> 0 corresponds to TRUE, value ==0 corresponds to FALSE. 2) String length 0 => FALSE, otherwise TRUE. 3) If only one character. It is not possible to convert from type AX IS and FRAME nor into type AXIS and FRAME. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Diagnostics Manual (DAsl), 03/2009 Remedy: Press the NC Stop key and select the function "C orrection block" with the softkey PROGRAM CORRECT. The correction pointer positions on the incorrect block. - Define variable type such that the initialization value can be assigned, or - Select initialization value in accordance with the variable definition. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
