Functional Overview
The PROFIBUS slave protocol driver may exist in a single port implementation. The
driver can be configured as a slave interface with other PROFIBUS devices. The
PROFIBUS slave port can be used to continuously interface with other PROFIBUS
devices over a PROFIBUS serial communication network.
5.2.1 About the PROFIBUS Protocol
PROFIBUS (Process Field Bus) is a widely-used, open-standards protocol created by a
consortium of European factory automation suppliers in 1989.
PROFIBUS is a master/slave protocol. The master establishes a connection to the
remote slave. When the connection is established, the master sends the PROFIBUS
commands to the slave. The MVI46-PDPS module works as a slave.
PROFIBUS supports a variety of network types. The network type supported by the
MVI46-PDPS module is PROFIBUS DP (Device Bus) version 0, which is designed for
remote I/O systems, motor control centers, and variable speed drives.
