Totalizer base
unit
conversion
factor 749 The user may select any of
the standard engineering
units, or custom units. For
custom units, the user must
provide a units tag name, a
base unit, and a conversion
factor for converting from the
base unit to the custom unit.
(value in Custom unit =value
in base unit * conversion
factor) R/W float N/A
Totalizer Base
Value 751 When the Totalizer is set to
Run mode after a Reset, it
will start incrementing /
decrementing from this base
value. R/W float N/A
Negative
totalizer Value 753 This is the Totalized Flow for
Reverse flow only. The
Negative Totalizer will
decrement when the Flow
Rate is a reverse flow
(negative flow value).
Note that the Reverse Flow
configuration setting must be
enabled to calculate negative
flow.
RO float N/A
Positive
Totalizer value 755 This is the Totalized Flow for
Forward flow only. The
Positive Totalizer will
increment when the Flow
Rate is a forward flow
(positive flow value). RO float N/A
