CNC lock function
23.15.1
Function overview
Note
The CNC lock function is a licensed option (article number: 6FC5800
-0AS71-0YB0).
The use of the CNC lock function requires purchase of the appropriate license from SIEMENS.
Note
It's machine manufacturer's responsibility
to ensure that the CNC lock function works properly and reliably.
NOTICE
License certificate
The company that created the CNC lock function (machine manufacturer or dealer) must retain the license certificate for
this option (CoL).
This certificate can be used as legitimation for SIEMENS should the PIN be forgotten. The owner of the certificate (CoL)
can have the machine unlocked.
The machine manufacturer can use the CNC lock function and the encrypted file that is created with the commissioning tool
Access MyMachine (AMM) to activate a lock date in the control system. This allows the use of the machine to be limited to
the time until the lock date is reached. The NC start of the control system is locked when the lock date is exceeded. An NC
program being processed in "AUTO" mode at this time is not interrupted.
The CNC lock function can be lengthened or deactivated with an additional encrypted file. The machine manufacturer sends
this file to the end user if the user has fulfilled the agreed obligations.
23.15.2
Requirements
The following preconditions must be met for using the CNC lock function:
● The option of the CNC lock function must be activated with a license key. For more information about how to activate the
optional functions, see Section "Activating the optional functions (Page 327)".
● A PLC project (of type 808D PPU14x/PPU16x) especially adapted to your machine tool must be downloaded into the
control system with PLC Programming Tool. The compatibility mode must be deactivated. The default PLC program
should never be used together with the CNC lock function. For more information about downloading a PLC project, see
the SINUMERIK 808D/SINUMERIK 808D ADVANCED Commissioning Manual.
● The AMM tool must be installed on your computer. For more information about AMM installation, see the SINUMERIK
808D/SINUMERIK 808D ADVANCED Commissioning Manual.
23.15.3
Restrictions
The CNC lock function supports the business model with time-limited use. This protects against unauthorized use beyond
the set interval. The direct access to the CNC, however, makes it possible to circumvent the function. The CNC lock function
does not offer an absolute protection against manipulation. Unauthorized use of the machine is precluded by locking "AUTO"
mode of the CNC. Because a running automatic program cannot be interrupted, this can extend the runtime beyond the lock
date. All other functions of the SINUMERIK control system remain available.
To permit the CNC lock function to act, support of the machine manufacturer is required. Consequently, the following note
and supplementary conditions must be observed when the CNC lock function is used.
Note
The CNC lock function is based on a connection of the PLC project to the SINUMERIK 808D/SINUMERIK 808D
ADVANCED control system. The control system consists of a combination of Panel Processing
Unit (PPU) and CF card with
system software.
