Definitions: The name of the macro to be selected by the instruction DEFINE is already defined in the control as:
Macro name
Keyword
Variable
Configured identifier.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block.
Select DEFINE instruction with another macro name.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12280 [Channel %1: ] Block %2 maximum macro length %3 exceeded
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string
Definitions: The string of instructions on the right side of the macro is limited to 256 characters. If an attempt is
made to define a longer character string under one macro (possible only through V.24 input of NC
blocks, because communication between operator panel and NCK is limited to a block length of 242
characters), an alarm is displayed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block.
Divide the functions defined under the macro into 2 macros.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12290 [Channel %1: ] Block %2 arithmetic variable %3 not defined
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string arithmetic variable
Definitions: Only the R parameters are predefined as arithmetic variables. All other arithmetic variables must be
defined with the DEF instruction before being used. The number of arithmetic parameters is defined
via machine data. The names must be unambiguous and may not be repeated in the control (excep-
tion: local variables).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block.
Define the required variable in the definition part of the program (possibly in the calling program if it is
to be a global variable).
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 parameter) 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!
