Sinumerik 840d sl Options activation on CNC machine

[yurimitev]

Hi all,

Is there any way to activate Options on Sinumerik 840d sl control other than buying license from Siemens?

I have an old 2008 machine with HMI Advanced SW7.3 and like to activate Measurement in Jog option.
Can EKB be used to generate the kay? Or something else?

Here are the options i want to activate:
6FC5800-0AM43-0YB0
6FC5800-0AP28-0YB0
6FC5800-0AP18-0YB0

Cheers

These options do not use EKB

I know but decided to ask anyway.

I read in Siemens forum an approach changing the MD and some other parameters. Making an backup without restarting and then loading the backup with the changed values. Not sure if this is possible workaround to activate some options?

“check your 840D system, if it is set to "0"?

Attention --if you want to change this kind of NCMD, you need follow the rule, otherwise your will have your system data lost.

#1--Back up your NC --NC archive.

#2--Change MD18342 to new value,! attention make sure DO NOT set NCMD actevated --DO NOT make POWER On reset,!!!!

at this moment --make NC archive (with new velue of MD 18342) , then reload this just backup archive, “
