I/O-Module Objects

Object 6421
hex
- Analog Input Interrupt Trigger Selection
The object defines which event is to trigger the transmitting of the
analog input data (TPDOs) by means of an interrupt signal.
The triggering event is defined for each input channel using a corre-
sponding sub-index of the object.
Warning
The behavior of the analog inputs is now adapted to the actuall
CANopen standard DS401.
This means, that the firmware versions ≥ 4.02 for BL20-GW-CANO-
PEN and version ≥ 2.02 for BL20-GWBR-CANOPEN are thus not
compatible with older firmware versions relating to the behavior of
the analog inputs.
Note
Objects 6421 – 6428
hex
can be used to control the event-triggered
transmission of the process input data. As well as these event-trig-
gered control objects, the transmission frequency of the process in-
put data is also controlled by means of objects 1800
hex
to 181F
hex
.
Attention
Remember that the object a "6423
hex
Analog input global interrupt
enable", page 4-149 must be used in order to enable the possibility
of transmitting the process input data using an interrupt signal!
