Example 5: Inhibit time > 0, Event time > 0, Inhibit time > Event time
The BFM data will be copied into the Object dictionary and a PDO will be sent every time when the data are
changed and the inhibit time is not running. If the inhibit time is active and the data are changed before the
inhibit time elapsed, the former data will not be sent as PDO.
If the data are not changed, no PDO will be sent if a data exchanged is triggered by BFM #20.
If no data exchange with new data is triggered by BFM #20, a PDO with the actual object dictionary data will
be sent when the event timer elapsed and the inhibit time is not active. If the inhibit time is active the event
timer starts running again without a PDO being sent.
The inhibit time in combination with the event timer allows new PDO data to be sent without the need to
retrigger the data exchange by BFM #20 for the case that during the first data exchange of new data the
inhibit time was active.
