Automated
updating of
machine
parameters
If a PLC:\_mpupdate directory is created, then files that automatically update
or expand the active and selected MP or OEM.SYS files when the control is
started can be saved here.
Files containing the name merge.* (merge.mp and merge.oem.sys) expand the
MP and OEM.SYS files by the entries contained in them. Files containing the
name overwrite.* (overwrite.mp and overwrite.oem.sys) contain updated
entries for the corresponding files, and overwrite entries with the same names
in the MP and OEM.SYS files.
This means that MP subfiles cannot be considered.
SavePlc=<name> The entire content of the PLC partition can be
saved in binary form as a .zip file. This makes it
possible to restore this software state including
the PLC files.
Here you enter the path and file name for the ZIP
file in which the entire PLC partition is saved in
binary format. Please consider the software
version when assigning the file name.
After an update, the -SETUP code number is
entered on a single-processor control, and the
Setup Back button is pressed in the iTNC control
panel on a dual-processor control in order to
reverse an update. The previous software version
is then reinstalled. The PLC partition is restored
from the *.zip file that was entered under
SavePlc= in the setup.ini file. Please note that a
subdirectory in which you want to save the *.zip
file must be created on the TNC partition before
the update. Otherwise the update is canceled
when backing up the old PLC partition.
Only updates from one full software version to
another can be reversed. You cannot reverse the
installation of service packs.
RestorePlc=<name> The Restore function is used to restore the PLC
data to a certain software state.
Here you enter the path and file name for the ZIP
file containing the PLC data state (in binary
format) appropriate to the NC software version to
be installed. This should be the ZIP file which was
saved with the SavePlc function, containing the
corresponding PLC state and saved on the PLC
partition.
