Overview of Alarms
NCK alarms
Definitions: The desired access authorization, programmed with the keyword REDEF, has not been set. The
desired protection level is either beyond the permitted value range or the protection level change is
not allowed.
(The REDEF instruction is only executable in INITIAL_INI blocks on SINUMERIK 840D, P1 (6/94)).
The protection level may be changed only if:
1. The current protection level is equal to or higher than the level originally defined, and
2. The new protection level is to be below the level originally defined.
The higher numerical values represent the lower protection levels. The lower 4 levels (from 7 to 4)
correspond to the keyswitch positions, and the upper 4 levels are associated with 4 passwords.
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.
- Use the REDEF instruction only in the INITIAL_INI block
- Using the operator panel, set the current protection level to at least the same level as that of the vari-
able with the highest level
- Program protection level within the permissible value range
- Only program new protection levels that are lower than the old values
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12495 Channel %1 Block %2 Change (definition) of data class %3 is not allowed
here
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Data class
Definitions: Change of the data class in this ACCESS file or definition in this GUD file (for file name see alarm
15180) not possible.
Priority of the new data class may only be smaller or the same as that of the definition file. This means
that DCS may only be programmed in SGUD (SACCESS), DCM not in UGUD and GUD9 (UAC-
CESS), DCU not in GUD9. DCI is allowed in all GUD and ACCESS files.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Program the data class of the area permissible for this GUD or ACCESS file.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12500 [Channel %1: ] Block %2 in this module %3 is not possible
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string
Definitions: The displayed keyword may not be used in this type of block and at this location (all files in the NCK
are designated as blocks).
Block types:
Program block
Contains a main program or subroutine
Data block
Contains macro or variable definitions and possibly an M, H or E function
Initialization block
Contains only selected language elements for data initialization
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.
Remove the displayed language elements (keyword) with its parameters from this block and insert in
the block provided for this purpose.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
