コード 12300: [Channel %1: ] Block %2 call-by-reference parameter missing on subroutine call %3

Parameters: %1 = Channel number %2 = Block number, label %3 = Source string Definitions: In the subroutine definition, a formal REF parameter (call-by-reference parame ter) has been specified with no actual parameter assigned to it. The assignment takes place in the subroutine call on the basis of the position of the variable name and not on the basis of the name! Diagnostics Manual (DAsl), 03/2009 Example: Subroutine: (2 call-by-value parameters X and Y, 1 call-by-reference parameter Z) PROC XYZ (INT X, INT Y, VAR INT Z): M17 ENDPROC Main program: N10 DEF INT X N11 DEF INT Y N11 DEF INT Z: N50 XYZ (X, Y); REF parameter Z missing or N50 XYZ (X, Z); REF parameter Z missing! 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. Assign a variable to all REF parameters (call-by-r eference parameters) of the subroutine when calling. No variable must be assigned to "normal" formal parameters (call-by-value parameters), as these are defaulted with 0. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
