In addition to data from the master port, status and error information generated
by the module can also be mapped into the internal database.
2.6 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
2.7 Port Physical and Protocol Specifications
The ProLinx module supports the PROFIBUS Master protocol as a Master on
either a Mono-Master or Multi-Master network.
