Digital Pressure Sensor with CANopen
10.3 Mapping Raw Pressure Data in PDO
Table 26 shows the procedure to map the Raw Pressure data
into PDO.
10.4 Transmission type configuration
The Digital Pressure Sensor with CANopen
be configured to give out the pressure reading in three different
ways:
1. The PDO is transmitted when a SYNC pulse is received,
providing the data is marked as updated. The data is
marked as updated whenever the pressure data changes.
An example of this transmission type is shown in Table 20.

2. The PDO is transmitted with every nth SYNC pulse
received, where n is a value
3. Between 1 and 240. An example of this transmission type
is shown in Table 21.
4. The PDO is transmitted when the Digital Pressure Sensor
with CANopen , Model DPS, event timer expires which
®
happens every 100 millisec by default. This event timer
value can be configured using the object 1800 with
subindex 05. This transmission type is independent of
the SYNC pulse. An example of this transmission type is
shown in Table 22.
