∼ Selection is unimportant.
YES State must be satisfied.
NO State is not permitted.
ASM If the "PROFINET IP (Ident profile)" mode is set, you must select PROFINET IO;
otherwise, select ASM.
If you want to send a command, make sure that the selection criteria are met according to
the table above.
The columns "Trigger source", "Result", "Result string" and "Control" correspond to the
selection in the user interface (Connections ➜ Integration ➜ Connection).
