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 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.
