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).
