3410 Series Gas Ultrasonic Meters Operations Manual Section 5: Calibrate and configure the meter

Configure digital input/outputs 63
5.6 Configure digital input/outputs
Digital input
The Daniel 3410 Gas Ultrasonic Flow Meters provides one digital input (referred to as DI1). The
polarity of the input is configured via the
DI1IsInvPolarity data point as follows:
FALSE - normal polarity (default setting), or
TRUE - inverted polarity
The digital input is not configurable via the Daniel MeterLink
Field Setup Wizard. It must be
configured via the Daniel MeterLink
Tools|Edit/Compare Configuration.
The value of the input is accessible via the
DI1 data point.
Digital Input calibration
The IsDI1 UsedForCal specifies whether digital input 1 (DI1) is used for general purpose (when set
to FALSE) or for synchronizing calibration (when set to TRUE). If used for calibration, the polarity
is determined by the
IsDI1ForCalActiveLow data point select one of the following:
FALSE - general purpose (default setting), or
TRUE - for synchronizing calibration
The
IsDI1ForCalActiveLow data point specifies the polarity for digital input 1 (DI1) when it is
configured (via
IsDI1UsedForCal) for use in synchronizing a calibration. See also IsDI1ForCalState-
Gated
.
FALSE = Cal Active High
TRUE = Cal Active Low (default)
The
IsDI1ForCalStateGated data point specifies the calibration gating for digital input 1 (DI1)
when it is configured (via
IsDI1UsedForCal) for use in synchronizing a calibration. When FALSE,
the calibration is started/stopped via an inactive->active edge; when TRUE, the calibration is
started via an inactive->active state change and stopped via an active->inactive state change.
The active edge/state is specified via the
IsDI1ForCalActiveLow data point.
FALSE = Cal Edge Gated (default)
TRUE = Cal State Gated
For detailed digital proving configuration, refer to Section 5.4.1.
Digital output
Select the function for which the digital output should be configured. Available options are
validity and direction.
The inverted operation option is useful if the output of the ultrasonic meter is reversed from
what a flow computer is expecting.This means that if the output normally outputs a HIGH for a
TRUE condition, selecting this checkbox will change the output to output a LOW for a TRUE
condition.
