Sinumerik Alarm 12330 Channel %1 block %2 type of parameter %3 incorrect

Sinumerik Alarm 12330 Channel %1 block %2 type of parameter %3 incorrect

Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Source string

Definitions:
When calling a procedure (a subroutine) it is found 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, however, 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: yes, 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.

Reactions:
– Alarm display.
– Interface signals are set.
– Correction block

Remedy:
Press the NC Stop key and select the function “Correction block” with the soft key PROGRAM CORRECT. The correction pointer positions on the incorrect block. Check transfer parameters of the subroutine call and define the application accordingly as call-by-value or call-by-reference parameter.

Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
