ATTENTION:
The ActivePrg and NonSkippedPrg POUs are created automatically, empty, in language selected on
the previous questions. Other POUs which are created manually by the user can be used in any
available language, except in redundant POUs which can’t be written in SFC language as it uses the
IEC timer as background. For further information see Limitations on a Redundant PLC
Programming.
ATTENTION:
The MainPrg POU will always be automatically generated in ST language, and cannot be changed
by the user. This POU calls the ActivePrg (only in the Active PLC) and NonSkippedPrg (in both
PLCs) POUs.
