1.5 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
