2.7 Function -specific display data
3. Activate the SGUD.DEF file.
The GUD variables for clearance control are now displayed under:
Operating area switchover > Parameters > User data > Channel spec. user data
SINUMERIK NCK
The new GUD variables, which are already being displayed, will only be detected by the
clearance control function and supplied with up-to-date values following an NCK POWER
ON RESET.
Note
Once the GUD variables have been created, an NCK POWER ON RESET must be carried
out in order for the clearance control function to update the GUD variables.
2.7.2 OPI variable
The "clearance control" technological function provides the following channel-specific OPI
variables as display data for the HMI application:
• SINUMERIK HMI Advanced
