5.2.3 Master/Slave Communication Phases
The communication between the Master and the slaves takes place in the
following phases:

Parameterization and configuration phase

Usable data transfer phase
Before a DP slave can be integrated into the usable data transfer phase, the
parameterization and configuration phase runs a device identification test that
verifies that the planned configuration matches the actual device configuration for
each slave in the PROFIBUS network. The test verifies that:

The device is actually there

It is the right type of device

The station address set on the device matches the station address in the bus
configuration

The formats, telegram length information, and bus parameters are correct
and

The number of configured inputs and outputs is correct
