For Modes 1 and 2 operation, the SM-PROFIBUS DP-V1 data format is specified as
NNCC, where NN is the non-cyclic data mode, and CC is the number of cyclic data
words.

The method used to map data to and from the PROFIBUS-DP network is similar to the
method used in the drive for mapping analog and digital I/O. The reference for the
source or target parameter is entered in the mapping parameter in the form MM.PP,
where:
MM = menu number of the target/source parameter
PP = parameter number of the target/source parameter.

A cyclic data channel does not use decimal points. For example, in Open Loop mode,
NOTE
digital speed reference 1 (Pr 1.21) has units of Hertz, accurate to 1 decimal place. To
write a value of 24.6Hz to Pr 1.21, the value must be transmitted as 246.
Block mapping can be used to map several words to consecutive drive parameters. Full
details about block mapping can be found in section 12.6 Block mapping .
When the data format is configured using Pr MM.05, the SM-PROFIBUS DP-V1 will
communicate using the same number of data words for IN and OUT data. It is, however,
possible to configure the SM-PROFIBUS DP-V1 to communicate with different numbers
of IN and OUT cyclic data words. Refer to section 12.8 Custom data formats for full
details.
If a mapping parameter is set to an invalid value (e.g. destination parameter is read
only, or parameter does not exist) the SM-PROFIBUS DP-V1 will indicate a
configuration error in the operating status parameter (Pr MM.06). The reason for the
configuration error will be indicated by the mapping status parameter (Pr MM.49). Refer
to section 10.7 Mapping status for more details.
The following sections show some example data formats that can be selected, and the
parameter mapping that will apply (by default) to each format.
