Bit Triggering event

.
0 1: "upper limit"
A exceeded - the value at the input has
exceeded the upper limit.
1 1: Input below "lower limit"
A - the value at the input is
below the lower limit.
2 1: Input changed by more than "delta"
A - the value at
the input has changed by a defined "Delta" value.
3 1: Input reduced by more than "negative delta"
A - the
value at the input has reduced by a defined "Delta"
value.
4 1: Input increased by more than "positive delta"
A - the
value at the input has increased by a defined "Delta"
value.
5 – 7 reserved
Note
The transmitting of the analog input data (TPDOs) by means of an
interrupt signal is triggered repeatedly with every change of the an-
alog input value if the value stays above the upper limit or below the
lower limit.
If another triggering event occurs at the same time (e.g. increase by
"Delta value"), the repeated transmitting is aborted.
Note
Several bits can be set simultaneously so that the transmitting of the
input process data can be triggered by several events.
