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:
•
•
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.
Digital Input calibration
The IsDI1UsedForCal 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:
•
•
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
IsDI1ForCalStateGated.

For detailed digital proving configuration, refer to
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.
Operations manual
The following fields are used to configure the frequency outputs selected to output
a mass rate. The fields are only enabled if the associated output's Content is set to
Mass rate.
Full scale mass rate used with output: Enter the mass rate to be equivalent to the
maximum frequency of the frequency output.
Mass/pulse: A read-only value showing the calculated inverse of the K-factor. Each
frequency output has its own register.
FALSE - normal polarity (default setting), or
TRUE - inverted polarity
FALSE - general purpose (default setting), or
TRUE - for synchronizing calibration
FALSE = Cal Active High
TRUE = Cal State Gated
