Checking timeout
You can query whether an input channel continuously receives SENT mes-
sages or not: As long as the return value of
P2_SENT_Get_Msg_Counter
keeps changing, new SENT messages are being received on the input chan-
nel.
CRC mode
With
P2_SENT_Set_CRC_Implementation
, the CRC check can be swit-
ched from calculation algorithm "legacy" to "recommended".
The calculation algorithm refers to both signals 1 and 2 as well as to the serial
message.
Setting sensor type
With
P2_SENT_Set_Sensor_Type
, the expected sensor type of a SENT sig-
nal is set. The module then checks the incoming signals whether they also
apply to the criteria of the selected sensor type, according to SENT specifica-
tion. If not, an error ID can be queried.
At the moment, the sensor types "throttle position sensor" and "single secure
sensor" are supported.
Modul revision
Differences between revisions are described below. The revision number is
located on the front panel.
Different revision characters mean different module characteristics and are
documented separately. A counter number is added for internal purpose.
The interface version is not visible from outside but can be queried by software:
Programming
The module is programmed comfortably with
ADbasic
instruction. The instruc-
tions are described in the Pro II software manual and in the online help of
ADbasic
.
Please note: For some commands you have to check with
P2_SENT_
Command_Ready
, whether the SENT interface is ready to process the next
command. Such commands are marked in the following table with *.
