July 2013 10.4 Protection Against Data Tampering 1893
10.4 Protection Against Data Tampering
Due to the possibility of networking the iTNC 530 and accessing it remotely,
protection from data tampering became necessary.
The following protection mechanisms are integrated:
 General disabling of data access by soft key
 Restricting access to the PLC partition
 Restricting access to parts of the TNC partition
This function was added for the end user. Please see the notes in the User’s
Manual.
General disabling of
data access
The soft key is normally not shown. To display the soft key:
 Enter the keyword REMOTE.LOCKSOFTKEYVISIBLE = YES in OEM.SYS.
Restricting access
to the PLC partition
In the standard setting, the PLC partition can be accessed via the LSV2
protocol using the code number 807667. To permit this access only with the
code number defined in OEM.SYS under PLCPASSWORD = (no longer with
807667):
 Enter the keyword REMOTE.PLCPASSWORDNEEDED = YES in OEM.SYS.
Code number 807667 is used during machine backup and full backup with the
LSV2 protocol to access the PLC partition. To permit this access only with the
code number defined in OEM.SYS under PLCPASSWORD = (no longer with
807667):
 Enter the keyword REMOTE.PLCPASSWORDFORCED = YES in OEM.SYS.
Soft key Meaning
This soft key disables access to the control using the LSV2
protocol, via both the serial and the Ethernet interfaces. It can
be displayed in any operating mode with the MOD key.
