Data format

Table 5.5 PROFIBUS-DP
Pr MM.05
The default data format is four cyclic words, each cyclic data channel is mapped to a
drive parameter. The default mappings are shown in Table 5.6.
The maximum number of 16-bit data words that is possible is 32 with only cyclic data, 31
NOTE
with Mode 1 non-cyclic data and 28 with PPO4 word mode.

Other data formats are also supported. For further details see section 7.2 Data
formats on page 24. The directions specified in Table 5.6 relate to the data direction as
seen by the master.

Network operating status

Table 5.7
Pr MM.06
The PROFIBUS-DP network activity can be monitored in the SM-PROFIBUS DP-V1
operating status parameter, Pr MM.06. When the SM-PROFIBUS DP-V1 is
communicating successfully with the PROFIBUS-DP master controller, Pr MM.06 will
give an indication of the number of cyclic data messages that are being processed per
second. This parameter is also available in menu 0 on the Digidrive SK (Pr 00.54).

If a mapping configuration error (see section 10.7 Mapping status ) or network error
(see section 10.9 Module error code ) is detected, the drive may trip.
