• $MN_MM_NUM_GUD_NAMES_CHAN = max. number of all channel-specific GUD
variables in the channel, error number = 2 shows that this value is too small.
• $MN_MM_GUD_VALUES_MEM = total value memory of all GUD variables together,
error number = 1 shows that this value is too small.
Switch control OFF - ON.
Machine data have been altered - now memory is reorganized
Machine data have been changed that define the NC user memory allocation. Data man-
agement has restructured the memory in accordance with the altered machine data.
- Alarm display.
No remedial measures are required. Any user data that are required must be input again.
Clear alarm with the RESET key. Restart part program
Limit of user memory has been adapted
Data management checks during power-up the actually available physical user memory
(DRAM, DPRAM and SRAM) with the values in the system-specific machine data 18210
MM_USER_MEM_DYNAMIC, MD 18220 MM_USER_MEM_DPR and MD 18230 MM_-
USERMEM_BUFFERED.
- Alarm display.
No remedial measures are required. The new maximum permissible value can be read
from the reduced machine data.
Clear alarm with the RESET key. Restart part program
Instead of %1 KB the system has only %2 KB of free user memory of type "%3"
%1 = Free memory capacity in KB defined for the control model
%2 = Actual maximum capacity of free memory in KB
%3 = Type of memory, "D" =non-battery-backed, "S" =battery-backed
The alarm can only occur after a 'cold start' (=NCK start-up with standard machine data).
The alarm is only a notice. There is no interference with any NCK functions. It shows that
the NCK has less free user memory available than specified by Siemens for this control
variant. The value of the actually available free user memory can also be taken from the
machine data $MN_INFO_FREE_MEM_DYNAMIC, $MN_INFO_FREE_MEM_STATIC.
Siemens supplies NCK with default settings that, depending on the model, have certain
(free) memory space available for the specific settings of the actual applications. The orig-
inal factory setting of NCK systems is thus that the alarm does not occur with a cold start.
- Alarm display.
Reasons for the message:
• The NCK contains compile cycle software, that uses so much memory space that the
hardware cannot provide the required memory.
• The NCK runs on hardware that is not intended for this NCK release (i.e. that has not
enough memory capacity).
• If the application runs properly with the remaining free user memory (i.e. can be started
up without any errors), the message can simply be ignored.
• If the actual application cannot be configured because there is not enough memory
capacity available, either the existing compile cycle must be reduced or, if possible, the
system must be upgraded with additional memory space.
Clear alarm with the RESET key. Restart part program
