SM-PROFIBUS-DP configuration using non-cyclic data
The SM-PROFIBUS-DP can be configured using CG Single Word or PPO 4 Word noncyclic data. This is useful when using a master controller to configure the drive; when a
drive is initialised only the node address MM.03 and the data mode MM.05, needs to be
set manually. The master can now use PPO 4 Word mode to setup the remainder of
the parameters.
Advanced
Features
The configuration parameters for the slot in which the SM-PROFIBUS-DP is located can
be accessed as Pr 60.PP. Any changes made to the configuration parameters will not
take effect until the SM-PROFIBUS-DP has been reset. The SM-PROFIBUS-DP can be
reset by writing a value of 1 to Pr 60.32. A brief interruption in PROFIBUS-DP
communications may be seen while the reset sequence is in progress.

data
status words
If the PPO 4 command is left in the data words, the write will be executed on every poll
of the network, effectively providing a continuous write. Care should be taken to ensure
the parameters for the write are setup before the TASK ID is changed from 0 to prevent
incorrect data being written.
