Configuration

• ; ACKN
If acknowledgement is possible for this messaging service (menu
option "Messaging services"), this feature can be activated here.
• ; ALW
▫ The message targets form a message sequence, in other words:
If a target of this sequence was informed successfully (including
acknowledgement), the message sequence is cancelled.
▫ If, however, a message target is to be informed in all cases, this
target can be marked under "ALW".
▫ Message targets that are marked with "I" have no influence on
the message sequence. In other words: Even if such a message
target was informed successfully, this does not end the message
sequence.
• Switch if … Message was successful
Here you can specify that one of the two digital outputs is to be
switched if:
▫ No message target was informed successfully.
One message target was informed successfully.
All message target were performed successfully.
▫ Message targets marked with an "I" are ignored.
