Conversion at the example of 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 with:
– C1093 (numerator).
– C1094 (denominator).
l
C1094 also determines 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
