4.10.4 0x2009 – The Count: Temperature is Less than the Limit
Use object 0x2009 (Temperature Span Underflow Count) to monitor the temperature history. The
count increments one each time the process value is more than the span end value.
Figure 13: Temperature Span Underflow Count
Reset the count when applicable. For example, after calibration.
4.11 To Monitor the Operation – Objects: 0x6000 – 0x6FFFF
4.11.1 0x6130 01/0x6130 02 – The Pressure and Temperature
Use object 0x6130 01 (Pressure Value) and object 0x6130 02 (Temperature Value) to monitor
the current process values. The process values include the calibration corrections (objects
0x2207 to 0x220A), and the applicable scale-factor (object 0x6123 01).
Use object 0x1A00 (Transmit PDO Mapping) to put the applicable data in the ‘Transmit PDO’.
4.11.2 0x6150 – The Pressure and Temperature Status
Use object 0x6150 (Status) to monitor the current status of the pressure and temperature output.
The individual bits of the status byte are used as follows:
•
Data is not valid.
• Value more than the limit.
• Value less than the limit.
The status of the pressure is linked to the temperature. If the temperature is out of range, bit 0 of
the pressure status will be set.
Status Description
0 The value is in the limits of 0x6148 and 0x6149.
1 The value is more than the limit of 0x6149.
2 The value is less than the limit of 0x6148.
