8 Safety-related Aspects of the User Program HIMatrix
Page 58 of 72 HI 800 023 E Rev. 1.01
Versions Beyond 7
Online test fields (OLT fields) can be used in the user program logic to display variables
while the controller is operating.
For more information on how to use OLT fields, enter OLT field in the SILworX online help.
Versions Prior to 7
The CPU switch Changing the variables in the OLT allowed defines the possibility to
change variablen online.
State Effect
OFF Variables cannot be changed.
It is possible to display the values of variables in the OLT fields, but not
to change them.
ON Variables can be changed.
The values of variables can be entered manually and set in the corre-
sponding OLT fields while the program is running. However, the set
value only applies until the program logic replaces it with a new value.

8.2.13 Program Documentation for Safety-Related Applications
The programming toll allows the user to automatically print the documentation for a project.
The most important documentation includes:
Interface declaration
Signal list
Logic
Description of data types
Configurations for system, modules and system parameters
Network configuration
List of signal cross-references
Code generator details
This documentation is required for the acceptance test of a system subjected to approval
by a test authority (e.g., TÜV). This acceptance test only applies to the user functionality,
but not to the safety-related modules and automation devices of the HIMatrix system that
have already been approved.
