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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12185 [Channel %1: ] Block %2 a bit combination with %3 is not permitted
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Address name
Definitions: A bit combination is not possible with the assignment to this address. Bit combinations are permitted
only for coupling adresses ( CPMBRAKE, CPMVDI and CPMAL ).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Change the part rogram.
If the data type of the address permits a bit combination, write the value of the address in a variable,
make a bit combination with the variable, and assign the variable to the address.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 COR-
RECT. The correction pointer positions on the incorrect block.
Correct the array definition, with multi-dimensional arrays define a second 2-dimensional array if nec-
essary and operate it with the same field index.
