Master/Slave Communication Phases; Port Physical And Protocol Specifications - ProSoft Technology ProLinx PDPM Protocol Manual

PDPM ♦ ProLinx Gateway
PROFIBUS DP Master
In addition to data from the master port, status and error information generated
by the module can also be mapped into the internal database.

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
