15122 Power ON after power failure: %1 data were restored, of which %2
machine data, %3 errors.
Parameters: %1 = Number of data
%2 = Number of machine data
%3 = Number of errors occurred
Definitions: Notification alarm. The alarm has no negative effect as long as %3 the number of errors occurred is
zero.
%1 indicates the number of elementary and complex data restoring steps which were taken after a
power OFF during power ON orduring a power failure to restore the persistent NCK data.
%2 indicates the number of restored machine data. If the value is larger than zero, another warm
restart (NCK reset) may be necessary to make the - possibly configuring - machine data changes prior
to the power failure effective.
%3 indicates the number of errors occurred during data restoring.
Reaction: Alarm display.
Remedy: As long as %3 number of errors occurred is zero, the alarm is only informative.
As long as %3 number of errors occurred is larger than zero, the alarm indicates a software error.
Further machining with the data is not recommended.
Please load a suitable archive file before continuing machining to avoid subsequent problems.
Please inform the authorized personnel/service department.
File /_N_MPF_DIR/_N_SIEMDIAGMEMPF_MPF contains information that may help Siemens for
error diagnosis.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
15150 [Channel %1: ] Block %2 reload from external aborted
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Execution from external was aborted because the reload buffer does not have enough machine func-
tion blocks (traversing blocks, auxiliary function, dwell time etc.). Background: When already executed
machine function blocks are released, memory becomes available in the reload buffer. If machine
function blocks are no longer released, nothing can be reloaded - this results in a deadlock situation.
Example: Definition of extremely long curve tables via execution from external.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Insert machine function blocks in the part progam.
- Increase the size of the reload buffer (MD18360 $MN_MM_EXT_PROG_BUFFER_SIZE).
- Decrease the size of the curve table (Note: Blocks within CTABDEF/CTABEND are not machine
function blocks).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
15160 [Channel %1: ] Block %2 wrong preprocessing configuration
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A block element is required, but the block element memory is empty.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Modify the block search configuration in
MD28060 $MC_MM_IPO_BUFFER_SIZE (decrease size of IPO buffer if necessary) or MD28070
$MC_MM_NUM_BLOCKS_IN_PREP.
Program Con- Clear alarm with the RESET key. Restart part program
