So-called identification bytes are transferred in the configuration telegram
of the PROFIBUS-DP master. These bytes determine the type of PPO for
the useful-data telegram.
These bytes can be assigned different values for selecting a particular
type of PPO (except for PPO type 1). For PPO type 4, for example, either
identification byte 0 = 245 and identification byte 1 = 0 can be entered or
only identification byte 0 = 245. If an unknown combination of
identification bytes is received, the CBP sets the bit "parameterization
error" in the diagnostic telegram to the PROFIBUS-DP master.
