Numeric Data
The numeric section of the data block transfer write defines the I/O
data - its location, format, and scaling.
The beginning of the numeric section is marked by the keyword
“numeric”, the number of values to be defined, and the data format.
AbRioCfg software checks the number of values to be defined against
the actual number of definitions and indicates an error if they do not
match.
The format can be one of the following.
All items must have the same format.
This line is followed by definitions for the I/O data values, each on a
row of the spreadsheet (or line of a text file). Each definition consists
of the following fields:
The BTW offset is the offset into the BTW data for the I/O data value.
Some modules have a separate polarity bit to indicate the sign of an
input. If the data being written is negative, the 1757-ABRIO module
sets the polarity bit.
Format Range of values
BCD 0 to 9999
Unsigned 0 to 65535
Integer -32768 to 32767
