4.10 To Monitor the Operation – Objects: 0x2000 – 0x2FFFF
4.10.1 0x2006 – The Count: Pressure is More than the Limit
Use object 0x2006 (Pressure Span Overflow Count) to monitor the pressure history. The count
increments one each time the process value is more than the span end value.
Figure 10: Pressure Span Overflow Count
Reset the count when applicable. For example, after calibration.
4.10.2 0x2007 – The Count: Pressure is Less than the Limit
Use object 0x2007 (Pressure Span Underflow Count) to monitor the pressure history. The count
increments one each time the process value is less than the span start value.
Figure 11: Pressure Span Underflow Count
Reset the count when applicable. For example, after calibration.
4.10.3 0x2008 – The Count: Temperature is More than the Limit
Use object 0x2008 (Temperature Span Overflow Count) to monitor the temperature history. The
count increments one each time the process value is more than the span end value.

Reset the count when applicable. For example, after calibration.
