代碼 12330: [Channel %1: ] Block %2 ty pe of parameter %3 incorrect

Parameters: %1 = Channel number %2 = Block number, label %3 = Source string Definitions: When calling a procedure (a subroutine) it is fo und that the type of the actual parameter cannot be converted into the type of the formal parameter. There are two possible cases: - Call-by-reference parameter: Actual parameter and formal parameter must be of precisely the same type, e.g. STRING, STRING. - Call-by-value parameter: Actual parameter and formal parameter can in principle be different providing conversion is basically possible. In the present case, howev er, the types are generally not compatible, e.g. STRING -> REAL. Overview of type conversions: - from REAL to: REAL: yes, INT: yes*, BOOL: yes1), CHAR: yes*, STRING: -, AXIS: -, FRAME: - from INT to: REAL: yes, INT: yes, BOOL: yes1), CHAR: if value 0...255, STRING: -, AXIS: -, FRAME: - from BOOL to: REAL: yes, INT: yes, BOOL: ye s, CHAR: yes, STRING: -, AXIS: -, FRAME: - from CHAR to: REAL: yes, INT: yes, BOOL: yes1), CHAR: yes, STRING: yes, AXIS: -, FRAME: - from STRING to: REAL: -, INT: -, BOOL: yes2), CHAR: only if 1 character, STRING: yes, AXIS: -, FRAME: - from AXIS to: REAL: -, INT: -, BOOL: -, CHAR: -, STRING: -, AXIS: yes, FRAME: - from FRAME to: REAL: -, INT: -, BOOL: -, CHAR: -, STRING: -, AXIS: -, FRAME: yes 1) Value <> 0 corresponds to TRUE, value ==0 corresponds to FALSE. 2) String length 0 => FALSE, otherwise TRUE. *) At type conversion from REAL to INT fractional values that are >=0.5 are rounded up, others are rounded down. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. 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. Check transfer parameters of the subroutine call and define the app lication accordingly as call-byvalue or call-by-reference-parameter. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
