Quick Start; Primary Objects; To Change The Operation - Node Id And Baud Rate; To Change The Operation - Objects: 0X1000 - 0X1Ffff - GE BAKER HUGHES DPS 5000 Series Instruction Manual

Chapter 3. Operation
• 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.
3.6.2 0x1017 – Error Control: Heartbeat Option
To use Heartbeat for error control, set applicable value for this object:
• 0x1017 (Heartbeat Time).
