Appropriate specifications NC MD 14/15 and/or 16/17 make it possible to protect general and
channel-specific R parameters. Channel-specific specifications apply to all channels. The
parameter area defined in MD 14-15 is password-protected, the area defined by MD 16-17 is
protected via the keyswitch. The latter is effective only when bit 3 of NC MD 5005 is "1". If
exceeded, range MD 16-17 has priority.

MD 18 is of significance in conjunction with Siemens cycle L960 only, and may not be
modified.
