User data

10.1

Overview

The defined user data may be displayed in lists.
The following variables can be defined:
● Data parameters (R parameters)
● Global user data (GUD) is valid in all programs
● Local user data (LUD) is valid in one program
● Program-global user data (PUD) is valid in one program and the called subroutines.
Channel-specific user data can be defined with a different value for each channel.
Entering and displaying parameter values
Up to 15 positions (including decimal places) are evaluated. If you enter a number with more
than 15 places, it will be written in exponential notation (15 places + EXXX).
LUD or PUD
Only local or program-global user data can be displayed at one time.
Whether the user data are available as LUD or PUD depends on the current control
configuration.
Note
Reading and writing variables protected
Reading and writing of user data are protected via a keyswitch and protection levels.
Searching for user data
You may search for user data within the lists using any character string.
Refer to the "Defining and activating user data" section to learn how to edit displayed user
