(PV) units. To change the relation between FV and PV, use the scale-factor objects and the zero
offset. This allows the reading of the pressure output in one of the alternative pressure units.
Example:
Set object 0x6123 01 to 100 (the scale-factor for pascal).
Figure 9: Scale of Pressure and Temperature Output
For a list of values of the alternative pressure units, refer to Appendix B, “Alternative Pressure
Units,” on page 49.
To change the scale data for temperature use the information above but with sub-index 02
replacing 01.
4.8.2 0x6131 01 – The Units for the Pressure Output
Use object 0x6131 01 (Pressure Value) to change the units for the pressure output.
Example:
Set Sub-index 0x01 to 0x00220000 = CANopen value for pascal.
For a list of values of the alternative pressure units, refer to Appendix B, “Alternative Pressure
Units,” on page 49.
4.8.3 0x6148 – The Local Limits (Minimum Pressure and Temperature)
Use object 0x6148 (Span Start – FP) to set the local limits for the pressure transducer operation.
Set the applicable minimum values for the pressure and temperature. Refer to “0x2007 – The
Count: Pressure is Less than the Limit” on page 16 and “0x2009 – The Count: Temperature is
Less than the Limit” on page 17.
4.8.4 0x6149 – The Local Limits (Maximum Pressure and Temperature)
Use object 0x6149 (Span End – FP) to set the local limits for the pressure transducer operation.
Set the applicable maximum values for the pressure and temperature. Refer to “0x2006 – The
Count: Pressure is More than the Limit” on page 16 and “0x2008 – The Count: Temperature is
More than the Limit” on page 16.
• Sub-index 01 sets the pressure.
• Sub-index 02 sets the temperature limit.
4.9 To Monitor the Operation – Objects: 0x1000 – 0x1FFFF
4.9.1 0x1001 – The Status of the Unit
Use object 0x1001 (Error Register) to monitor the current status of the unit. Also see “0x6150 –
The Pressure and Temperature Status” on page 17.
