Introduction; Applications; Summary Of Facilities - GE BAKER HUGHES DPS 5000 Series Instruction Manual

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.
