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.
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:
