OEM PIN forgotten for CNC lock
Fault description
The machine manufacturer or dealer has forgotten the OEM PIN that was assigned during the initial creation and so can no
longer create a valid activation file for the associated control system.
The machine manufacturer or dealer must contact the Siemens Hotline and provide the following information to unlock the
machine:
● License certificate (CoL) for the option of the CNC lock function
● Serial number of the CF card
● Serial number of the hardware (PPU)
● Software version of the CNC software
Note
The software version of the CNC software can be found on the PPU HMI through the following operations:
+ → → →
After receiving the activation file from the Hotline, the machine manufacturer or dealer can import the file into the control
system to unlock the machine.
The unlocking acts, however, only on the hardware of the control system (PPU). The PLC project is not unlocked. For this
reason, the original PLC project appropriate for the machine must be available.
