2.5 Software
2.5.1 Designation of the Software
The logic unit features a separate software for the NC and the PLC. The NC software is identified with an eight-digit number. The ID number is displayed briefly after the TNC is switched on:
If you press the MOD key in any operating mode, you can display the ID numbers of the NC software, the DSP software and the setup disks. If the hardware contains flash EPROMs, the letter ”F” is displayed before the NC software Id. Nr.
Software type The following software versions are available for the TNC 426 and TNC 430 controls:
Due to restrictions on the export of the TNC, HEIDENHAIN can also supply a special export version. This export version differs from the standard control though the installed NC software type. HEIDENHAIN releases a new NC software type whenever it introduces extensive new functions.
Certain software versions do not run on all hardware versions. Please note the following table, which assigns each NC software version to a hardware version:

2.5.2 Software Option
The following software options are available for the TNC 426 and TNC 430:
nDigitizing with triggering touch probe
nDigitizing with triggering and measuring touch probes
If you have ordered a TNC with an option, the software number will be supplemented by an option number displayed after the TNC is switched on.
The TNC can also be retrofitted with one of the options. Please contact HEIDENHAIN for further information.
2.5.3 PLC Software
The PLC software is stored on the hard disk of the TNC. You can order a PLC commissioning program directly from HEIDENHAIN. With the PLC
development software PLCdesign, the PLC program can be very easily adapted to the requirements of the machine.

If no current conversational languages are on the hard disk, load the English language through machine parameter MP 7230.x. If a software exchange becomes necessary, HEIDENHAIN provides new EPROMs and setup disks, or a new complete setup for controls with flash EPROMs.
Information about the cycles
Change the OEM cycles into binary format before reconversion, otherwise the TNC will not recognize these cycles, and will add ERROR blocks to the NC programs. These ERROR blocks must be deleted manually.
After an NC software exchange, to be able to use the latest HEIDENHAIN cycles together with your existing customized cycles, you will need the PC software CycleDesign to insert the new cycles in your *.CDF file. The new
*.CDF file and the appropriate CONSTCYC.CDC for the HEIDENHAIN cycles are provided on the setup disks of the NC software. For further information, refer to the User’s Manual or the help texts for CycleDesign.
Entries in the log file
If errors occur during conversion, the TNC will display error messages and log them in the log file. During the NC software switch, the name and path of a log file can be entered in the header after Path =; the extension *.A must be used. If no entry is made in this line, the file TNC:\CVREPORT.A is created.
Each error message contains nError message
nError number nError cause nFile concerned Example:
