Virtualflowcomputer table details

  • Last UpdatedApr 24, 2025
  • 3 minute read

The virtualflowcomputer table is used by the Virtual Flow Computer (VFC) application. The virtualflowcomputer table is used to contain configuration data and totalized runtime data for a set of meters operating in parallel. The virtualflowcomputer table contains the following internal fields:

Internal Field Name

Data Type

Description

accessFlag

displayname

Display that accesses this record.

autoInh

oas_boolean_t

Is the VFC inhibited due to an auto-inhibit operation?

autoInhPath

path

The path to the status or multistate point to auto-inhibit.

batchGuid

GUIDstring

When the Batch ID is changed for a given Virtual Flow Computer in ADE, a GUID is automatically generated. This field is not visible in ADE.

batchId

batchname

Optional value to use for Batch ID in batch tracking.

csw

double

Correction for sediment or water (0-100%).

DailyIntegrated

PeriodicIntegration

Daily integrated data.

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.
