Thanks for the pointer, but reading the docs raises other questions. They
say that the max value is 8192K, yet I have several totalizers wih .OUT
values that go to 9 digits. I checked out the faceplate, and it does
reference the .OUT parameter, but uses formatting to get 10 places plus a
decimal place. Does this mean that every digit after 7 is bogus?

Corey,
According to B0193AX, Rev. K, "... the block saves the running accumulator
in extended precision format to minimize truncation errors. However, the
block stores the output (OUT) as a single precision float of 7-digit
resolution with a maximum value of 8,192,000 (8192 K) and a
user-specifiable range."
I was just reviewing the specs of the ACCUM block for a small project I'm
involved with.
