Overview of Alarms 01/2008 NCK alarms 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 Continuation: Clear alarm with NC START or RESET key and continue the program. 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 Continuation: Clear alarm with NC START or RESET key and continue the program. 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 Continuation: Clear alarm with NC START or RESET key and continue the program. 12200 Channel %1 block %2 symbol %3 cannot be created Parameters: %1 = Channel number %2 = Block number, label %3 = Symbol in the source block Definitions: The symbol to be created with the DEF instruction cannot be created because: - it has already been defined (e.g. as variable or function) - the internal memory location is no longer sufficient (e.g. with large arrays) Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Make the following checks: - Check with the text editor whether the name to be allocated in the active program cycle (main program and called subprograms) has already been used. - Estimate the memory requirements for the symbols already defined and reduce these if necessary by using fewer global and more local variables. Program Continuation: Clear alarm with NC START or RESET key and continue the program. 2-138 © Siemens AG, 2008.
