Data in RAM When the iNC is being prepared for a software update, then all of the important information
in the RAM is stored automatically on the hard disk .
This includes:
MODE settings (position display, etc.)
AXIS LIMIT (traverse range limits, datums)
RS 232/422 SETUP (assignment, baud rate, etc.)
Touch probe calibration data
Nonvolatile PLC memory range (markers and words from a specific group)
Once the NC software has been updated successfully, the saved data is restored
automatically.
Preparing machine  Move the swivel head to a defined position or basic position.
Contact your machine manufacturer for more information.
 Move the tool changer to a defined position.
Contact your machine manufacturer for more information.
 Move the axes away from the hardware limit switches, to the middle of the traverse range.
Converting data Many file types (e.g. all NC programs with the extension *.H) are stored on the iTNC hard disk
from binary to in binary format (the essential advantage is the fast access time). However, the binary format
ASCII of the different software versions may not be the same (older software uses binary format A,
newer software binary format B). Therefore the current binary format must be converted into
the neutral ASCII format before updating an NC software. After the update the ASCII format
is reconverted into the binary format of the software version. This ensures that the new NC
software can operate with files in the correct binary format.

Check whether you have enough free space available on the hard disk for the files to be
converted (at least 0.5 times the already occupied memory). If not, read out several large files
with TNCremoNT and delete them from the iTNC hard disk.
 To accelerate the converting process delete any NC programs in the TNC partition that you no
longer require. Contact the machine operator for information.
 Press the EMERGENCY STOP button of your machine.
 Press the following key combination:
23 – 282
Note
Your data medium can also be connected to the control via CIMCO-NFS. For this purpose
the CIMCO-NFS software must be installed. The connection setup is described in the
iTNC 530 Technical Manual.
When using CIMCO-NFS the control directly accesses the data in the folder of the data
medium. Therefore, the zipped NC software files do not have to be transferred with
TNCremoNT.
Caution
Conversion of the data is required for each software update!
Reason:
Different binary formats of the different software versions.
Non-volatile PLC markers and words in the RAM may have been moved during a software
update. By means of the data conversion these PLC markers and words are automatically
cached and restored.
 Select Programming and Editing operating mode.
 Prepare iTNC for entry of code number.
 Enter the code number.
