Sample Rate This is the Totalizer sampling rate. The
Totalizer value will be updated at the
configured rate. The rate may be configured
in increments of 125 ms. The shorter the
sampling rate, the more frequently the
Totalizer Value will be updated.
Totalizer Base Val When the Totalizer is set to Run mode after
a Reset, it will start
incrementing/decrementing from this base
value.
Exceed count This value indicates the number of times the
Totalizer Value has reached the user-
configured Maximum Totalizer Value.
Totalizer Status Latency
Each time the Totalizer Value has reached
the Maximum Totalizer Value, the Max
Totalizer Status will be set. The user-
configurable Totalizer Status Latency
indicates the length of time this status will
be active before it is reset.
Totalizer Status This parameter indicates the current status
of the Totalizer Value. Possible values are:
-
Good
- Bad
- Totalizer OFF

limits will be rounded off to 7 digits (this includes the digits before and after the decimal
point) and rest will be filled with 0’s (digits 8 and above) to represent the values in IEEE
floating point format.
This will be the value that gets written to the device.
For example:
