Siemens SINUMERIK 808D - Page 92

Description: File name with file path where the data backup file is stored if the persistent memory
is reconfigured.
18030 HW_SERIAL_NUMBER N05 -
- Hardware series number STRING PowerOn
-
- 1 - - - 2/- M
Description: During power on of the control, a unique hardware serial number is stored in this MD:
● For Powerline series modules this is the serial number of the NCU module
● For Solutionline series modules this is the serial number of the CF card, or the
unique number of the MCI module in the case of PC-based systems
This data cannot be written.
18040 VERSION_INFO N05 -
- Version STRING PowerOn
-
- 5 - - - 2/- M
Description: Version identifiers of the system software
18050 INFO_FREE_MEM_DYNAMIC N01, N02, N05 S7
- Display data of the free volatile memory DWORD PowerOn
-
- - 1310720 0 268435456 1/- M
Description: The data is used for
a) the manufacturer's presetting of the memory size [ bytes ] available to the user
for each channel after cold restart.
b) displaying the available volatile memory [ bytes ]
The data cannot be written.
The contents of the data state how much volatile memory is available per channel for
increasing the volatile user data storage area via MD.
It is advisable to check whether the available memory is sufficient before increasing,
for example, the number of LUDs, number of functional parameters, or the size of the
IPO buffer.
If necessary, proceed step by step:
● increase by 1, note (old) value
● NCK startup (= 'warm start' or NCK reset), read off new value
● memory requirement = new value - old value
18060 INFO_FREE_MEM_STATIC N01, N02, N05 S7
- Display data of the free nonvolatile memory DWORD PowerOn
-
- - 409600 0 48234496 1/- M
Description: The preassigned value specifies how many bytes, as a minimum, are free for the user
when the NCK runs up with a 'cold restart'.
The contents of the data state how much nonvolatile memory is available during startup
for configuration of the active and passive file system and other functions.
