1. Introduction
The transducers in the DPS 5000 series measure absolute pressure or gauge to produce fast,
accurate pressure data through a Controller Area Network (CAN) bus interface. All these
transducers include:
• CANopen software standards.
• Digital output.
• CAN bus serial communications interface.
Note: The prerequisites for this instruction manual are prior knowledge of the CANopen
protocols and standards. See Appendix C., “Bibliography,” on page 55 for more details.
1.1 Applications
The DPS 5000 series is for automated systems using a CAN bus network and CANopen
software standards. The pressure transducers in the DPS 5000 series are ideal for automated
systems with:
• A large amount of digital pressure data.
• A high level of accuracy over a wide temperature range.
• A sophisticated level of software control.
1.2 Summary of Facilities
Because all the transducers in the DPS 5000 series use CANopen software standards, each
transducer includes a CANopen Object Dictionary. Use the CANopen Object Dictionary to do
these primary tasks:
• Monitor the current pressure and temperature data.
• Tag the type of data. For example: Oil-mbar, H2O-mbar.
• Read the factory defined operating data. For example, the pressure range, and the
type of sensor.
• Set the update frequency for the pressure and temperature data.
• Set the pressure units.
• Monitor the current status.
• Read and set the last and next calibration date.
• Set new calibration values.
• Set local pressure and temperature limits for use with the internal out-of-limit
counters.
• Monitor the number of times the pressure is not in the specified limits.
• Monitor the number of times the temperature is not in the specified limits.
• Restore all the factory default values for the CANopen Object Dictionary.

3. Operation
This section includes:
• The procedures to start and change the operation of the pressure transducer.
• The available data from the pressure transducer.
Note: 0x identifies a hexadecimal value. Object 0x1800 02 = Index 0x1800,
Sub-index 0x02 (refer to Appendix A., “CANopen Object Dictionary,” on page 19).
3.1 Start Operating
After a successful installation (refer to Chapter 3., “Operation,” on page 5) and to start
operating requires:
• A CANopen software package to access the CANopen Object Dictionary.
• Operation of the CANopen network, including the Network Initialization Process (the
Boot-up process) and/or the applicable configuration procedures.
3.2 Procedures
1. Complete the boot-up procedure (defined in the CANopen standard) for the CAN bus
network. After boot-up the pressure transducer enters a “pre-operational” mode and
in this mode responds to SDO and LSS messages.
2. The pressure transducer must be set to its operational state to respond to sync
messages and to be fully operational.
Figure 3-1: Default ‘Transmit PDO’ Operation
Note: This shows how the pressure transducer uses the default values to transmit a
Process Data Object (PDO).
The readings can be filtered by a range of preset finite impulse response (FIR) filters. (refer to
“0x220D to 0x2218 – The Filter System” on page 10).
Use the CANopen software package to receive the PDO and get access to the CANopen
Object Dictionary.
Use the CANopen software package to change these values:
CAN bus SYNC
(Cycle period in ms)
PDO COB-ID = 0x181
Object 0x6130 01:

• Values set with the Layer Setting Services (LSS).
• Values in the CANopen Object Dictionary.
3.3 Quick Start
Get the current pressure and temperature values by using object 0x6130:
• Sub-item 01 returns the pressure value in the default pressure units.
• Sub-item 02 returns the temperature in degrees Celsius.
3.4 Primary Objects
The following procedures identify the primary objects that can be changed and monitored.
Refer to Appendix A., “CANopen Object Dictionary,” on page 19 for a complete list.
3.5 To Change the Operation - Node ID and Baud Rate
Use the CANopen Layer Setting Services (LSS) to change these primary objects in the
pressure transducer:
Note: To respond to LSS messages the pressure transducer must be in pre-operational
mode.
• The node ID (default value = 2).
• The baud rate (default value = 250 kbits/s).
In addition, object 0x210C can be used to modify the node ID. Object 0x210D holds the baud
rate.
To make changes to these and other data dictionary objects permanent, save them and cycle
the power to the sensor.
When using the LSS, the device must be identified. Object 0x1018 (identity) contains the
identification data. Refer to Appendix C., “Bibliography,” on page 55.
3.6 To Change the Operation - Objects: 0x1000 - 0x1FFFF
3.6.1 0x100C to 0x100E - Error Control: Node Guarding Option
To use Node Guarding for error control, set applicable values for these objects:
• 0x100C (Guard Time).
• 0x100D (Life Time Factor).

Refer to Appendix C., “Bibliography,” on page 55.
3.6.3 0x1010 01 – To Save Changes to the Data Dictionary
Use object 0x1010 01 (Store Parameter Field) to save the data dictionary to non-volatile
storage.
Example:
Set the value to 0x65766173 = evas (in ASCII)
Note: This does not overwrite the factory data and the sensor can be returned to its
factory state by using 0x1011 as described below.
3.6.4 0x1011 01 – To Re-apply the Factory Values
Use object 0x1011 01 (Restore Default Parameters) to re-apply all the factory values.
Example:
Set the value to 0x64616F6C = daol (in ASCII)
Having re-applied the factory values, the sensor should be power cycled for the values to be
applied.
3.6.5 0x1800 02 – The PDO Transmission (Type or Period)
Use object 0x1800 02 (Transmission Type) to change the type of PDO transmission or the
period between each PDO transmission (refer to Appendix C., “Bibliography,” on page 55).
3.6.6 0x1A00 – The Data in the ‘Transmit PDO’
Use object 0x1A00 (Transmit PDO Mapping) to change the data sent in the ‘Transmit PDO’
(maximum size = 8 bytes).
To change the transmit PDO, set bit 31 of 0x 1800 1 “COB-ID” to 1 and set 0x IA00 1 to 0.
After changing the PDO the process should be reversed.
Example:
To monitor the current status of the pressure value, set Sub-index 0x02 to
0x61500108 = Object 0x6150 01, 1 byte of data.
3.6.7 0x1F80 - NMT Start-up
Use object 0x1F80 to set the start-up mode of the sensor.
Status Description

3.7.10 0x220D to 0x2218 – The Filter System
The DPS 5000 sensor can support a wide range of sample rates and filters to give a choice of
speed and accuracy. There are five filters, preset to a selection of values. Each filter is built of
two parts; a pre-scaler and a group of coefficients. It is beyond the scope of this manual to
describe the creation of these values.
The data dictionary item “Selected FIR Filter” at 0x2217 is used to choose a filter. When
changing to another filter, be aware of the 3 dB settling times below before taking new
values.
3.7.11 0x2304 – The Tag for the Type of Data
Use object 0x2304 (Tag) to identify the type of data that the pressure transducer supplies
(maximum: 10 characters). For example: Oil-mbar.

3.8.1 0x6120 to 0x6124 – The Scale Data for Pressure and
Temperature Output
The pressure transducer uses a two-point calibration to calculate the pressure output. The
two-point calibration includes the relation between the Field Value (FV) units and the
Process Value (PV) units. To change the relation between FV and PV, use the scale-factor
