Overview of Alarms
NCK alarms
12170 Channel %1 block %2 identifier %3 defined repeatedly
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Symbol in block
Definitions: The symbol shown in the error message has already been defined in the active part program. Note
that user-defined identifiers may occur more than once if the multiple definition occurs in other
(sub)programs, i.e. local variables may be redefined with the same name if the program has been
exited (subprograms) or has already been concluded. This applies both to user-defined symbols
(labels, variables) and to machine data (axes, DIN addresses and G functions).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: The symbol already known to data management is displayed. This symbol must be looked for in the
definition part of the current program using the program editor. The 1st or 2nd symbol must be given
a different name.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12180 Channel %1 block %2 illegal chaining of operators %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Chained operators
Definitions: Operator chaining means the writing in sequence of binary and unary operators without using any form
of parentheses.
Example:
N10 ERG = VARA - (- VARB) ; correct notation
N10 ERG = VARA - - VARB ; error!
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Formulate the expression correctly and unambiguously making use of parentheses. This improves
clarity and readability of the program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12190 Channel %1 block %2 variable of type ARRAY has too many dimensions
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Array with variables of type STRING may be no more than 1-dimensional, and with all other variables
no more than 2-dimensional.
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
CORRECT. The correction pointer positions on the incorrect block.
Correct the array definition, with multi-dimensional arrays define a second 2-dimensional array if
necessary and operate it with the same field index.
Program Clear alarm with NC START or RESET key and continue the program.
