The PROFIBUS Master protocol driver exists as a single port implementation.
The driver can be configured as a Class 1 and Class 2 PROFIBUS Master to
interface with other PROFIBUS slave devices. The unit is also used for
configuration of the nodes on the PROFIBUS network. It provides access to
standard and extended diagnostic information, as well as freeze/sync capability,
Acyclic Communication (DPV1, Class 1 and 2), and Alarm Handling (DPV1). The
PROFIBUS Master port can be used to continuously interface with PROFIBUS
slave devices over a serial communication interface (RS-485).
