Read/Write (R41,025 – R41,026) Total Decimal Places
Sets the number of decimal places (0-3) being read for Total 1, (words 41,016 and 41,017)
and Total 2, (words 41,018 and 41,019).
With 3 decimal places, the largest value that can be read is 2,147,483.648.
With 2 decimal places, the largest value that can be read is 21,474,836.48.
With 1 or 0 decimal places, the largest value that can be read is 100,000,000.
Although the word registers are limited to reading a maximum value as indicated above
for the defined number of decimal places, the overflow bits of Instrument_Status2 (Word
31) will only reflect an overflow condition (Bits 1 and 2 set to 1) when the decimal place is
set to 2 or 3.
When set to 2 or 3, the word registers will stop accumulating at the indicated values
however, the LUI will continue to totalize to a value of 100,000,000. Should this condition
exist, prior to resetting the totalizer registers, be sure to observe and record the totalized
value as displayed on the LUI. Not doing this could cause a reporting discrepancy in
expected material totals within the process.
Once the internal totalizer registers realize a value of 100,000,000, the internal registers
will perform a rollover, causing the display of the LUI to start from a value of 0. This will
also cause the Instrument_Status2 word bits to reset to 0.
Example: R41,025
Bits 0 and 1 are used to indicate the number of decimal places being read in Total 1:
words 7 and 8.
Bit 15 is used to indicate if the decimal place is too large to read the total value correctly.
If three decimal places are being read in Total 1:
Bits 15 14
0 0
If three decimal places are being read in Total 1, and the value is too large to be read with
three decimal places:
Bits 15 14
1 0
