Digital Pressure Sensor with CANopen
CHAPTER 4 - SETTING UP
4.1 Procedure to Get Started
In order to operate in the host network it is necessary to en-
sure:
1.
The Node-ID of the Digital Pressure Sensor with
CANopen
, Model DPS, is not the same as any other node
®
on the CANbus network.
2.
The bit rate of the Digital Pressure Sensor with CANopen
Model DPS, matches that of the network to which it is
being connected.
These parameters are configured using the layer settings ser-
vices. These parameters are configured prior to connecting the
Model DPS in the host network.

4.2 Node-ID Configuration
The Node-ID is used to provide unique communication object
identifiers for each CANopen
ing of the Node-ID can be performed:
1.
Prior to connection using the switch mode global
command called Point-to-Point Configuration.
,
®
2.
On the target network using the switch mode selective
command called Network Configuration.
Table 3 shows the process of performing point-to-point Node-
ID Configuration. Table 4 shows the process of performing
Node-ID Configuration on network.
