Overview of Alarms
NCK alarms
12481 Channel %1 block %2 program attribute %3 not allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string
Definitions: The attribute used in the PROC instruction is not permitted in the current operating mode.
The attribute SAVE, for example, is not allowed in a technology cycle.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press button NC STOP and select the function "Compensation block" using softkey PROGAM
CORRECT. The cursor jumps to the incorrect block. Then delete the invalid program attribute.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12490 Channel %1 block %2 access permission level %3 is not valid
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string
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
CORRECT. 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
variable 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 Clear alarm with NC START or RESET key and continue the program.
