The Pressure/Flow Monitoring (Pressmon) application uses the pressmon table to record information about the volumetric variance within each region where pressure is being monitored. The pressmon table contains the following internal fields:
|
Internal Field Name |
Data Type |
Description |
|---|---|---|
|
allowflw |
oas_boolean_t |
Allow a flow rate alarm to exist without the pressure point being in alarm? |
|
autoreset |
oas_boolean_t |
Clear the pressure and flow rate sample arrays after a communication outage? |
|
dataset |
doas_dset_slot |
This field indicates the dataset to which the record is assigned. Datasets are used to associate the record with the privileges assigned for each system mode. Once a record is assigned to a dataset value, the dataset can only be changed to a value for which the system has a privilege record. |
|

Description of the pressmon record, up to 47 characters in length. |

flags |
For information on the flag structure, see Flag structure details. |
|
flwtimeconf |
unsigned int |
The maximum amount of time (in minutes) Pressmon should check for flow rate deadband violations after the associated pressures exceed the second deadband. |
|
group |
groupslot |
This field shows the group that this point is associated with for alarming. |
|
method |
enum_pressmonMethod |
Indicates how the pressure readings are to be used and accounted for. |
|
name |
pntname |
The unique name of this pressmon record. |
|
pressure.presslt1 |
analogslot |
The first analog point for which you would like to track pressure information. |
|
pressure.presslt2 |
analogslot |
The second analog point for which you would like to track pressure information. |
|
pressure.presslt3 |
analogslot |
The third analog point for which you would like to track pressure information. |
|
pressure.pdown_db1 |
float |
The negative deadband value for pressure.presslt1. In cases where the actual pressure is less than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
pressure.pdown_db2 |
float |
The negative deadband value for pressure.presslt2. In cases where the actual pressure is less than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
pressure.pdown_db3 |
float |
The negative deadband value for pressure.presslt3. In cases where the actual pressure is less than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
pressure.pup_db1 |
float |
The positive deadband value for pressure.presslt1. In cases where the actual pressure is greater than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
pressure.pup_db2 |
float |
The positive deadband value for pressure.presslt2. In cases where the actual pressure is greater than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
pressure.pup_db3 |
float |
The positive deadband value for pressure.presslt3. In cases where the actual pressure is greater than the estimated pressure, Pressmon uses this deadband when comparing the estimated and actual pressures. |
|
read2_conf |
unsigned int |
The number of iterations AVEVA Pipeline Operations for Liquids performs when checking for violations of the second deadband after the pressure or flow rate point has violated the first deadband. |
|
rtu |
remoteslot |
This field is used for sorting and filtering purposes only. It has no effect on data processing. |
|
samplesize |
unsigned int |
The number of previous samples (between 2 and 15, inclusive) Pressmon uses when calculating the slope in order to estimate the next value. |
