Usage of safety CPU with V3 non-safety CPU PM56xx
C.5.2.1
Migration from AC500 V2 to AC500 V3 (compatibility mode)
You can migrate an existing Automation Builder project with AC500 V2 CPUs and safety CPUs
with cyclic non-safe data exchange to a project with AC500 V3 CPUs. If you do not want to
change the safety application, enable the checkbox "Prevent automatic modification of safety
application" . When the checkbox is enabled, no variable assignments between safety and non-
safety CPU are done.
In CODESYS Safety, no folder "CyclicNonSafeDataExchange" and no corresponding global
variables are generated. The safety application remains unchanged. On safety CPU, data
exchange with non-safety CPU is done with specific function blocks. Refer to the corresponding
description, available via www.abb.com/plc - document no. 3ADR025195M0202.
On non-safety CPU, data exchange with safety CPU is done via the variables defined in tables
"From safety CPU" and "To safety CPU" .
