To use this function, you need to only execute the PI service. Here, no initialization of the PI service is required.
By default, MD14512 [19].2 = 0, which indicates that the control system will automatically delete the password after NC
restart. If you want the control system to remember the last used password every time the NC restarts, you need to set
MD14512 [19].2 = 1.
Note
The "CNC lock function" is a licensed option (article number: 6FC5800
-0AS71-0YB0).
Note
It's machine manufacturer's responsibility to ensure that the CNC lock function works properly and reliably.
The company that created the CNC lock function (machine manufacturer or dealer) must retain the license certificate for
this option.
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 created with Access MyMachine (AMM)
application 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 function 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.
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 148)".
● 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 project
should never be used together with the CNC lock function. For more information about the operations with PLC
Programming Tool, see Section "PLC Programming Tool (Page 205)".
● The AMM tool must be installed on your computer. For more information about AMM installation, see Section "Installing
the software tools (Page 41)".
