Activating
Each technology function loaded by compile cycle creates a function-specific global NCK
machine data within the range of numbers from 60900 to 60999 in accordance with the
following pattern:
$MN_CC_ACTIVE_IN_CHAN_<
Example:
$MN_CC_ACTIVE_IN_CHAN_
$MN_CC_ACTIVE_IN_CHAN_
Activation for 1st NC channel
The technology functions are activated in the first NC channel via
$MN_CC_ACTIVE_IN_CHAN_<
The meaning of machine data bits Bit1 - Bit31 are described in the relevant function
description (TE1 - REn).
After the NCK is next booted up, the activated technology functions are integrated into the
system software.

SINUMERIK powerline
The first time a bit is set in one of the function-specific NCK machine data:
$MN_CC_ACTIVE_IN_CHAN_XXXX[0]
the following alarm is displayed:
Alarm 4400 "MD modification causes reorganization of the buffered memory (data loss)"
And you are warned that all user data (part programs, tool data, etc.) will be deleted on the
