Manipulating NC data
If NC data is to be manipulated, in relation or depending on its old value (e.g.: For operators
+=, *=, etc.), ensure that this data is also included in the NC output data.
Provision of NC machine data
In the case of "Origin of data", "Initial state" or "Overall reset", all NC data is always provided.
For this purpose, the package sets the required machine data to the following values before
it provides all machine data:
N11210 $MN_UPLOAD_MD_CHANGES_ONLY='H0' ; machine data backup only for changed
machine data.
N11212 $MN_UPLOAD_CHANGES_ONLY=0 ; data backup type of the active file system.
These two machine data items retain these values over the package execution and afterwards.
If this is not wanted, you can set this machine data to the desired value in a manipulation task.
Loading an archive into the control
When loading an archive to organize the memory, the NC requires certain machine data
contained in the upload files prefixed to INITIAL.INI (NC.OPT, GLOBAL.IN,
SCALING.INI and CHAN.INI). Before manipulation, the package loads only data from
INITIAL.INI to memory, performs the manipulation operations and then writes back all the
data. All previously existing data is written back to its old position, both in the INITIAL.INI and
in the upload files.
Additional data is attached to the data of INITIAL.INI, and according to the following rule,
also to the data of the upload files:
● NC.OPT, if the identifier starts with $ON
● GLOBAL.INI, if the identifier starts with $MN or $MA
● SCALING.INI, if the identifier starts with $MN or $MA
● CHAN.INI, if the identifier starts with $MN or $MC
If NC data is manipulated, the line checksum is generated and attached to all data.
SINAMICS data
Drive data is manipulated, based on the DRV archive area.
Display data
For SINUMERIK Operate, data is read from section [BTSS-Settings] of file hmi_md.ini
in the search sequence siemens → addon → oem → user, but written back only to
hmi_md.ini at user. When deleting data, this results in a reset to a user-specified value of
preceding files in the search sequence.
Comparing tasks in Diff
Manipulation tasks can also be used in Diff for comparison.
