Conversion
In the example, the conversion is made at FB FEVAN1.
l The data format of the target code is important for the conversion (see attribute table).
l Adapt the input signal to the data format of the target code:
– C1093 (numerator).
– C1094 (denominator).
l 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.
l For target codes with % scaling the formula for conversion must include a scaling factor (see
example 1).
