Value

Description

OverwriteMode

In Overwrite Mode, the oldest messages are always discarded if the ring buffer is full.

AcknowledgeMode

In Acknowledge Mode, if the ring buffer is full, the oldest acknowledged messages are discarded. If only non-acknowledged messages are in the list, these remain and the latest incoming messages are discarded.
If messages are acknowledged with the function block input bAck, they can be overwritten by new messages.
