Format Word (R43,997)
Format word is an unsigned integer that contains a value that represents a certain
decimal offset.
The decimal offset indicates how the remote system must interpret the integer value
that is stored in the parameter access register. The following table shows how different
parameter values can be shown based on a register value (integer) of 1234.
Decimal Offset Example
0 0 1,234
1 -1 12,340
2 -2 123,400
3 -3 1,234,000
4 -4 12,340,000
5 -5 123,400,000
6 +1 123.4
7 +2 12.34
8 +3 1.234
9 Percent 12.34%
Examples of using the format word for both the index values and the decimal offset
value are shown below:
