Conversion
In the example, the conversion is made at FB FEVAN1.
z Thedataformatofthetargetcodeisimportantfortheconversion(seeattributetable,
chapter 9.5.2).
z Adapt the input signal to the data format of the target code:
– C1093 (numerator).
– C1094 (denominator).
z C1094 also fixes the decimal positions of the target code:
– Set C1094 according to the existing decimal positions of the target code. The number of
decimal positions can be obtained from the code table.
– 0.0001 ≙ no decimal positions.
– 0.001 ≙ one decimal position.
–0.01≙ two decimal positions.
–0.1≙ three decimal positions.
–1≙ four decimal positions.
z For target codes with % scaling the formula for conversion must include a scaling factor (see
example 1).
