Double-click on the "Cyclic non-safe data exchange" instance.
ð A warning is displayed that safety requirements are not fulfilled when using the cyclic
non-safe data exchange.
Carefully read the warning and confirm it.
Without confirming, you are not able to define variables and therefore not able to use the
data exchange.
For details on checkbox "Prevent automatic modification of safety application" refer to
Ä Appendix C.5.2.1 "Migration from AC500 V2 to AC500 V3 (compatibility mode)"
on page 400.

Table "From safety CPU" : Variables which shall be written by the safety CPU and read by
the non-safety CPU.
Table "To safety CPU" : Variables which shall be written by the non-safety CPU and read
by the safety CPU.
Build or rebuild the non-safety application in Automation Builder. Do this after each modifi-
cation for cyclic non-safe data exchange, e.g., new variables added or existing variables
updated.
ð The variables are created and can be used in non-safety application.
