Working With A Machine-Specific Plc Program; Displaying Additional Drives - HEIDENHAIN TNC 320 Operating Instructions Manual

Working with a machine-specific PLC program

Some machine tool builders provide more than one PLC program for
the programming station, each specific to a different type of machine.
Please contact your machine tool builder to request a description of
the adapted PLC program's functions.
In order to increase protection of files and other data, the
machine tool builder can encrypt the PLC, making it more
difficult for third parties to access this information.
HEIDENHAIN points out that no data encryption method
offers 100 % protection of the data, especially against
access, damage or destruction by unauthorized persons,
etc. Therefore, HEIDENHAIN cannot guarantee that data
stored there will not be tampered with, and as a
consequence cannot assume liability for any resulting
damage.
