Introduction

Overview
GUD are Global User Data that users can define themselves on the NCU and subsequently
use in the NC. WinCC lets you visualize these tag values.
● To use the GUD tags of the NCU in the TIA Portal, you must first import (Page 81) them.
● If you work with GUD arrays, read the corresponding Notes for GUD arrays in the TIA
Portal (Page 76).
● Whenever you change the DEF files, you must also repeat the import or recreate the user
database (Page 81).
● If you have extended the GUD tags offline in theTIA Portal, you must copy the modified
DEF files back to the NCU (Page 87).
The DEF files of the GUD database used in the TIA Portal must match the DEF files in
the NC so that the WinCC RT Advanced Runtime can correctly access the GUD tags.
At an early phase in the configuring, coordinate the GUDs to be used on the NCU and in
the TIA Portal. If subsequent additions are required, attach these at the end of the DEF
files, below the existing data. If you make changes to the complete DEF file, you must
reconnect all GUD of this DEF file.
Note
Data consistency between the TIA Portal and SINUMERIK Operate
If you change something in the data in SINUMERIK Operate after the import into the
TIA Portal, these changes are not automatically synchronized between the systems.
Repeat the import process, therefore, if you change something in the GUD data in
SINUMERIK Operate.
